&lt;br /&gt;&lt;span class="postbody"&gt;
VERY THOUGHT PROVOKING POST FROM MADAM ALPA SHETH&amp;nbsp;&amp;nbsp;,,&amp;nbsp;&amp;nbsp;ADMIRE&amp;nbsp;&amp;nbsp;HER FORESIGHTED VIEWPOINT FOR THIS TOUGH, BUT CHALLENGING PROFESSION OF STRUCTURAL ENGG VIS A VIS AI TOOL. 
&lt;br&gt;
&lt;br&gt;I THINK ALL TOOLS / AIDS FOR&amp;nbsp;&amp;nbsp;STRUCTURAL DESIGN WORK - WHICH PROVIDE RELIEF TO DESIGNER ARE WELCOMED, BUT HUMAN TOUCH IS MUST, WITHOUT WHICH, ANY LAPSE COULD COST IRREPARABLE LOSS. 
&lt;br&gt;
&lt;br&gt;EVEN SOFTWARES FOR ST DESIGN ARE USED WITH CAUTION&amp;nbsp;&amp;nbsp;SO THAT GIGO IS NOT FED,, 
&lt;br&gt;NOT FAMILIAR WITH AI, BUT FEEL THAT IT COULD ACT AS VALIDATION TOOL ONLY AS A THIRD OPTION BY DESIGNERS, - CAN NOT SAY AS MYSELF TOTALLY ALOOF ON THIS SUBJECT,, 
&lt;br&gt;
&lt;br&gt;THANKING MADAM FOR BRINGING THIS AI ASPECT TO DISCUSSION,&amp;nbsp;&amp;nbsp;
&lt;br&gt;HOPE OTHER MEMBERS CAN SAY MORE ON THIS. 
&lt;br&gt;
&lt;br&gt;THANKS AND BEST REGARDS 
&lt;br&gt;
&lt;br&gt;
&lt;br&gt;
&lt;br&gt;Quote=&amp;quot;alpa_sheth&amp;quot;]Dear SEFIans, 
&lt;br&gt;
&lt;br&gt;You may have noticed that the discussions on SEFI and other international platforms for structural engineers&amp;nbsp;&amp;nbsp;have quietened down a bit, even though the number of subscribers to SEFI are growing. This is because there is a belief (I think mistaken) that AI will be able to give us quicker responses than our fellow engineers on SEFI&amp;nbsp;&amp;nbsp;in case of a str. engg. query one may have. 
&lt;br&gt;
&lt;br&gt;I know I typically go to an AI platform&amp;nbsp;&amp;nbsp;for medical issues. And I must admit that the responses I get on ChatGPT or Perplexity or Claude seem very informed and are almost always aligned with the Doctor's diagnosis or medicine protocol. But&amp;nbsp;&amp;nbsp;since AI is based on LLMs, it is hardly any surprise that it performs well in&amp;nbsp;&amp;nbsp;in medicine; Many tasks in medicine&amp;nbsp;&amp;nbsp;are pattern-recognition problems which AI can do very well. AI can read scans, flag anomalies, summarize records and much other stuff. Medical work often involves processing large amounts of text or lab data, which too are areas where AI performs well. That is why fields like radiology, pathology, etc. have been early beneficiaries of AI.
&lt;br&gt;
&lt;br&gt;But it is erroneous for us to think that AI can perform just as well in Structural Engineering. Structural Engg does not necessarily lend itself as well to LLMs as Medicine does. Structural engineering is more constrained by physics, safety, and real-world validation. Structural engineering&amp;nbsp;&amp;nbsp;needs exact compliance with codes, materials behavior, load paths, and so on. It is&amp;nbsp;&amp;nbsp;much harder to automate in the AI straitjacket because Structural engineering decisions must hold up in the physical world and involve a lot of computation. While AI can assist with analysis and&amp;nbsp;&amp;nbsp;design optimization,&amp;nbsp;&amp;nbsp;the final responsibility still depends on engineering judgment, codes, and verification.
&lt;br&gt;
&lt;br&gt;
&lt;br&gt;We have a curious situation&amp;nbsp;&amp;nbsp;where as my colleague Sanjeev says, &amp;quot;Humans come less on SEFI while hundreds of AI bots attack us every day and want to eat up each byte&amp;nbsp;&amp;nbsp;of data&amp;nbsp;&amp;nbsp;humans created over decades to train their models. SEFI and likes are in great demand by AI models as food for one-time training.&amp;quot; AI platforms know what&amp;nbsp;&amp;nbsp;young engineers don't- it is a platform like SEFI that is&amp;nbsp;&amp;nbsp;the true goldmine of structural engineering knowledge, fed as it has been by hundreds&amp;nbsp;&amp;nbsp;of informed engineers&amp;nbsp;&amp;nbsp;over thousands of hours across&amp;nbsp;&amp;nbsp;than two decades. 
&lt;br&gt;
&lt;br&gt;The human- generated wealth of knowledge such as at SEFI has been consumed without permission- just simply stolen if I may, from across domains of knowledge by AI models. Anthropic AI admitted to consuming millions of paperbooks and once consumed,&amp;nbsp;&amp;nbsp;destroyed physical copies and when copyright lawsuits happened,&amp;nbsp;&amp;nbsp;they offered a measly $3000 per title. Imagine someone buying a book authored by you, and destroying its relevance and its need altogether by offering free knowledge learnt from that book which was your&amp;nbsp;&amp;nbsp;lifetime's work.&amp;nbsp;&amp;nbsp;An&amp;nbsp;&amp;nbsp;AI&amp;nbsp;&amp;nbsp;bot can scrape entire SEFI site within minutes and train it's neural networks while SEFI spent decades to create it. 
&lt;br&gt;
&lt;br&gt;Sites such as SEFI are being overtaken today by&amp;nbsp;&amp;nbsp;AI sites in terms of traffic&amp;nbsp;&amp;nbsp;because users get instant answers from AI rather than engaging with the community. But there is a catch. There will be, in all likelihood, a Kodak moment as they say.&amp;nbsp;&amp;nbsp; The &amp;quot;Knowledge Cannibalization&amp;quot; Argument : A very real phenomenon sometimes called &amp;quot;Model Collapse&amp;quot; or the &amp;quot; *Data Exhaustion&amp;quot; problem is lurking around the corner. 
&lt;br&gt;
&lt;br&gt;There is a BIG RISK: If the community dies, the &amp;quot;training data&amp;quot; for future AI,&amp;nbsp;&amp;nbsp;also dies. AI cannot easily learn new, unpatched software bugs or novel human theories if the forums where those are discussed become ghost towns. AI in structural engineering is dependent on its survival to sites like SEFI. But by&amp;nbsp;&amp;nbsp;trying to making these forums redundant,&amp;nbsp;&amp;nbsp;AI is essentially &amp;quot;eating its own tail.&amp;quot; Without new human interaction, AI models will eventually start training on AI-generated content, which leads to a degradation in quality. New version of these models show no significant improvements over previous one due to data exhaustion... No new human generated knowledge.
&lt;br&gt;
&lt;br&gt;I think it is time that all of us wake up to what's happening and reignite the creative, thinking engineer in us who survived without AI and will now survive, despite it and hand-in-hand with it. 
&lt;br&gt;
&lt;br&gt;warmly,
&lt;br&gt;Alpa&amp;nbsp;&amp;nbsp;Sheth[/quote]&lt;/span&gt;&lt;br /&gt;

Posted: Thu Jul 02, 2026 9:42 am (GMT 0)&lt;br /&gt;
&lt;br /&gt;&lt;span class="postbody"&gt;
I defer from your views,
&lt;br&gt;
&lt;br&gt;1. AI is a tool like a KNIFE, you can use it to save lives and Take lives, it is not the Mistake of the KNIFE, it is the users responsiblity 
&lt;br&gt;
&lt;br&gt;2. AI does a fantastic JOB in strctural engineering also, what you take days it does in seconds, you should know how to use it and understand it and apply the correct interpetation (most of the time it is correct)
&lt;br&gt;For example , you give a existing .XLS file and ask it to write a generic program based on that XLS file , it does a fantastic JOB, you should be aware of what you want and validate some cases then you have a much easier tool than excel at your finger tips.
&lt;br&gt;(say you have a footing design program, and you have a STAAD output file, you can make it write a program that will replicate your footing design exactly, and apply for all the support reactions of the STAAD output file thus avoiding juggling between your XLS file and .ANL file)
&lt;br&gt;
&lt;br&gt;3. If your anology of Buying the book and giving the knowledge free is WRONG,&amp;nbsp;&amp;nbsp;then what about our entire learing system from our childhood ?? in what way are we diffrent from what the AI companies are doing ?? we buy any book and have paid the value of the BOOK , the knowldedge gained from that is OUR PROPERTY and we are allowed to do what we want if you do not want your knowledge to be shared then DO NOT WRITE THE BOOK. (that is what exactly happended with our AyurVedic medicines , they died because that doctor did not want it to be shared and thousands of wonderful medicens died with them)
&lt;br&gt;
&lt;br&gt;4. And regarding comunity knowldege sharing , if you observe&amp;nbsp;&amp;nbsp;99% of the people here are only to view and only 1 % contribute , the 99% is NOT intrested in Sharing OR NOT capable of sharing. (see anyone puting an EXCEL sheet , most of them protect it with a PW , i see those as a Instagram or a Facebook post only for the adrenaline of likes and views)
&lt;br&gt;for those who think their EXCEL sheets posted here with password are safe, it takes 2 mts for AI to crack it)
&lt;br&gt;
&lt;br&gt;5. to survive the AI world , a real time experince is a MUST , as i have seen it was able to replace my 35 years of coding in 3.5 months, but my domain knowledge can and will never be replaced.
&lt;br&gt;
&lt;br&gt;so all the young engineers who want to survive the AI onslaught, go back to your BASICS , learn to design using the CALCULATOR&amp;nbsp;&amp;nbsp;, understand reading the drawings , how to give various Loads, etc those things AI cannot or atleast as of now REPLACE the FEEL of a Engineer, it has already REPLACED the computitational aspect of the engineer, if you are a programmer understand how to break up your project into smaller parts through classes etc&lt;/span&gt;&lt;br /&gt;

STRUCTURAL ENGINEER AS QUANTITY SURVEYOR 
&lt;br&gt;
&lt;br&gt;
&lt;br&gt;OFTEN STRUCTURAL ENGINEERS ARE, APART FROM DESIGN WORK, ASKED TO GIVE QUANTITIES OF&amp;nbsp;&amp;nbsp;CONCRETE INGREDIENTS LIKE CEMENT, COARSE SAND AND STONE AGGREGATE,, 
&lt;br&gt;
&lt;br&gt;MOSTLY THESE ITEMS IN DESIGN OFFICE ARE COMPUTED BY QUANTITY SURVEYOR
&lt;br&gt;
&lt;br&gt;AND STRUCTURAL ER FEELS HANDICAP.,, 
&lt;br&gt;
&lt;br&gt;BEING A PRIMARY MEMBER OF DESIGN FAMILY,&amp;nbsp;&amp;nbsp;I THINK IT IS ALWAYS BETTER THAT AN ENGINEER OF STRUCTURAL DESIGN, MUST BE AWARE AND ABLE TO CALCULATE. 
&lt;br&gt;
&lt;br&gt;FOLLOWING PRESENTATION CAN HELP :-
&lt;br&gt;A) CONCRETE INGREDIENTS 
&lt;br&gt;FOR EXAMPLE MIX 1:1.5:3&amp;nbsp;&amp;nbsp;=&amp;nbsp;&amp;nbsp;1+1.5 + 3 = 5.5 
&lt;br&gt;CONCRETE QUANTITY = 1.0 M3 
&lt;br&gt;
&lt;br&gt;
&lt;br&gt;DRY VOLUME OF INGREDIENTS NEEDED = 1.54 X 1.0 = 1.54 M3 
&lt;br&gt;CEMENT SP. GRAVITY = 1440 KG/ M3 
&lt;br&gt;1 BAG = 50 KG 
&lt;br&gt;HENCE CEMENT BAGS NEEDED = 1.54 X ( 1/ 5.5 ) X(1440 / 50 ) = 8.07 bags 
&lt;br&gt;
&lt;br&gt;COARSE SAND (CS) = 1.54 X ( 1.5/5.5 ) = 0.42 M3 = 0.42/(0.305^3) = 14.8 cft ~ 15 cft
&lt;br&gt;
&lt;br&gt;Stone Aggregate = 14.8x 2 = 29.6 cft ~ 30 cft 
&lt;br&gt;
&lt;br&gt;Some percentage of wastage is added for actual consumption 
&lt;br&gt;
&lt;br&gt;( B)&amp;nbsp;&amp;nbsp;INGREDIENTS OF CEMENT MORTAR 
&lt;br&gt;
&lt;br&gt;CEMENT MORTAR&amp;nbsp;&amp;nbsp;1: 3&amp;nbsp;&amp;nbsp;= 1 + 3 = 4 
&lt;br&gt;
&lt;br&gt;MORTAR&amp;nbsp;&amp;nbsp;= 1.0 M3 
&lt;br&gt;
&lt;br&gt;DRY VOLUME OF INGREDIENTS = 1.33 X 1.0 = 1.33 M3 
&lt;br&gt;
&lt;br&gt;CEMENT = 1.33 X ( 1/4 ) X ( 1440 / 50) = 9.6 bags 
&lt;br&gt;
&lt;br&gt;SAND = 1.33 X ( 3/4)&amp;nbsp;&amp;nbsp;= 1.0 M3 =&amp;nbsp;&amp;nbsp;1.0 / ( 0.305^3) = 35.3 CFT 
&lt;br&gt;
&lt;br&gt;( C)&amp;nbsp;&amp;nbsp;CEMENT REQUIRED FOR WALL TILING 
&lt;br&gt;
&lt;br&gt;TAKING 1.0 M3&amp;nbsp;&amp;nbsp;CEMENT 
&lt;br&gt;
&lt;br&gt;CEMENT NEEDED = 1.0&amp;nbsp;&amp;nbsp;X 1440/50 = 28.8 BAGS 
&lt;br&gt;
&lt;br&gt;APPENDIX 
&lt;br&gt;
&lt;br&gt;ESTIMATION OF VOLUME OF MORTAR REQUIRED 
&lt;br&gt;WALL AREA 3*4 = 12 SQM 
&lt;br&gt;
&lt;br&gt;TAKING MORTAR AS 20 MM 
&lt;br&gt;VOL OF MORTAR = 0.020 * 12 = 0.24 M3 
&lt;br&gt;APPLY DRY VOLUME FACTOR FOR MORTAR AS 1.33 
&lt;br&gt;
&lt;br&gt;ESTIMATE OF CEMENT FOR WALL TILING 
&lt;br&gt;TAKING 20 MM&amp;nbsp;&amp;nbsp;AND CALCULATE AS ABOVE 
&lt;br&gt;DRY VOLUME FACTOR 1.00 FOR CEMENT SLURRY 
&lt;br&gt;
&lt;br&gt;FOR CONCRETE DRY VOLUME FACTOR = 1.54 
&lt;br&gt;
&lt;br&gt;
&lt;br&gt;KINDLY CORRECT ABOVE PRESENTATION&amp;nbsp;&amp;nbsp; , WHEREVER&amp;nbsp;&amp;nbsp; FEEL AMENDS&lt;/span&gt;&lt;br /&gt;

Chlorides and Sulphates are not good for Rcc Work, especially foundations in contact with such soils 
&lt;br&gt;
&lt;br&gt;Better Use CRS ( Corrosion resistant Steel) Reinforcement and SRC ( Sulphate resistant concrete) in case foundation soil contains that . Generally in coastal areas this was used to as protection , some three decades earlier, but now more better brands are available snd can be checked. 
&lt;br&gt;
&lt;br&gt;But it would be wise enough to go deeper to surpass upper soil layers containing these&amp;nbsp;&amp;nbsp;chemicals. ,, 
&lt;br&gt;
&lt;br&gt;Also where columns concrete locations , good Soil be brought and filled up around
&lt;br&gt;
&lt;br&gt;Just a layman's viewpoint,, 
&lt;br&gt;
&lt;br&gt;Other sefi members, more experienced, Sri Suraj Singh saheb can deliberate better.&lt;/span&gt;&lt;br /&gt;

So True Madam. all our thoughts are very well explained. There is no substitute to&#65533;gain knowledge in the discussion and interaction&#65533; with experienced&#65533; engineers who have gone through numerous real world problems and solved them without any AI existence. Eventually&#65533; there will be saturation in the AI world and&#65533; if we don&amp;#39;t cultivate our logical engineering brain and fully&#65533;depend on AI, there will be degradation in the AI result

Hi,
&lt;br&gt;
&lt;br&gt;You seem to be comparing the requirements of IS 456-2000 with ACI 318. 
&lt;br&gt;The requirements of IS 13920 are quite different. Refer Clause 7.1.1 The minimum width of the column into which a special moment resisting frame beam is passing through or anchoring into has to be&amp;nbsp;&amp;nbsp;20 times&amp;nbsp;&amp;nbsp;dia of the max dia of beam bar and not less than 300 mm. So if you have 32 dia bar in beam, the min width of the column would have to be 640 mm. 
&lt;br&gt;Hope this clarifies. 
&lt;br&gt;
&lt;br&gt;
&lt;br&gt;best regards,
&lt;br&gt;Alpa Sheth 
&lt;br&gt;&lt;/span&gt;&lt;table width="90%" cellspacing="1" cellpadding="3" border="0" align="center"&gt;&lt;tr&gt; 	  &lt;td&gt;&lt;span class="genmed"&gt;&lt;b&gt;Jaya_kumar wrote:&lt;/b&gt;&lt;/span&gt;&lt;/td&gt;	&lt;/tr&gt;	&lt;tr&gt;	  &lt;td class="quote"&gt;Hello All,
&lt;br&gt;
&lt;br&gt;I have been comparing the developed length for rebars in interconnected members per ACI318&amp;nbsp;&amp;nbsp;section 25.4.3 vs Indian codes(SP34 or IS13920) that define the developed length for rebars. 
&lt;br&gt;
&lt;br&gt;ACI demands a certain distance of straight rebar from critical section. This is called Ldh. The hook (90&lt;SUP&gt;0&lt;/SUP&gt; or 180&lt;SUP&gt;0&lt;/SUP&gt;) follows and it is of standard design. The hook length post the 90&lt;SUP&gt;0&lt;/SUP&gt; or 180&lt;SUP&gt;0&lt;/SUP&gt; bend does not factor in total developed length calculation. 
&lt;br&gt;
&lt;br&gt;So, for a rebar of certain size to have fully developed on a beam joining with that column, there is a minimum depth of column that needs to be provided. For example, with M20 concrete and Fe415 rebar, the minimum straight length of rebar ranges from 7inch to 12 inch based on other factors. So Ldh decides the width or depth of column when interfacing with another member.
&lt;br&gt;
&lt;br&gt;However, in IS Code, the tension development length does not have a set straight length after critical section. All it requires is a certain length of rebar after critical section to meet the development length. That length can be before the 90&lt;SUP&gt;0&lt;/SUP&gt;
&lt;br&gt;
&lt;br&gt;For example, a FE550D grade 20mm rebar in M30 concrete we need about 50 times the dia of the rebar, which is 1000mm. If I'm able to provide 1000mm of rebar after critical section I can use this bar on any column depth from 9&amp;quot; to 1000mm. 
&lt;br&gt;
&lt;br&gt;For 9&amp;quot; column,the straight length after critical section may be about 6 inches, but the rest of 34 inches falls after the 90 degree bend. 
&lt;br&gt;
&lt;br&gt;Does this actually work in real life cases? Does the rebar after 90degree bend provide any meaningful resistance to the tension developed at critical section? Won't the concrete at the 90deg bend crush due to tension starting a brittle failure rather than a ductile failure?
&lt;br&gt;
&lt;br&gt;I see often 20 or 16mm rebars are bent about 6-8&amp;quot; after the 90&lt;SUP&gt;0&lt;/SUP&gt; bend with not even providing the required Ld per IS Code, that too inside the 9&amp;quot; columns. What is the opinion of the engineers on this topic?
&lt;br&gt;
&lt;br&gt;This is my first post, so kindly bear with me if I made any mistakes. Thank you all for your time.&lt;/td&gt;	&lt;/tr&gt;&lt;/table&gt;&lt;span class="postbody"&gt;&lt;/span&gt;&lt;br /&gt;

Subject: The Great AI Heist of Structural Engineering Treasures&lt;br /&gt;
Posted: Mon Jun 29, 2026 9:42 am (GMT 0)&lt;br /&gt;
&lt;br /&gt;&lt;span class="postbody"&gt;
Dear SEFIans, 
&lt;br&gt;
&lt;br&gt;You may have noticed that the discussions on SEFI and other international platforms for structural engineers&amp;nbsp;&amp;nbsp;have quietened down a bit, even though the number of subscribers to SEFI are growing. This is because there is a belief (I think mistaken) that AI will be able to give us quicker responses than our fellow engineers on SEFI&amp;nbsp;&amp;nbsp;in case of a str. engg. query one may have. 
&lt;br&gt;
&lt;br&gt;I know I typically go to an AI platform&amp;nbsp;&amp;nbsp;for medical issues. And I must admit that the responses I get on ChatGPT or Perplexity or Claude seem very informed and are almost always aligned with the Doctor's diagnosis or medicine protocol. But&amp;nbsp;&amp;nbsp;since AI is based on LLMs, it is hardly any surprise that it performs well in&amp;nbsp;&amp;nbsp;in medicine; Many tasks in medicine&amp;nbsp;&amp;nbsp;are pattern-recognition problems which AI can do very well. AI can read scans, flag anomalies, summarize records and much other stuff. Medical work often involves processing large amounts of text or lab data, which too are areas where AI performs well. That is why fields like radiology, pathology, etc. have been early beneficiaries of AI.
&lt;br&gt;
&lt;br&gt;But it is erroneous for us to think that AI can perform just as well in Structural Engineering. Structural Engg does not necessarily lend itself as well to LLMs as Medicine does. Structural engineering is more constrained by physics, safety, and real-world validation. Structural engineering&amp;nbsp;&amp;nbsp;needs exact compliance with codes, materials behavior, load paths, and so on. It is&amp;nbsp;&amp;nbsp;much harder to automate in the AI straitjacket because Structural engineering decisions must hold up in the physical world and involve a lot of computation. While AI can assist with analysis and&amp;nbsp;&amp;nbsp;design optimization,&amp;nbsp;&amp;nbsp;the final responsibility still depends on engineering judgment, codes, and verification.
&lt;br&gt;
&lt;br&gt;
&lt;br&gt;We have a curious situation&amp;nbsp;&amp;nbsp;where as my colleague Sanjeev says, &amp;quot;Humans come less on SEFI while hundreds of AI bots attack us every day and want to eat up each byte&amp;nbsp;&amp;nbsp;of data&amp;nbsp;&amp;nbsp;humans created over decades to train their models. SEFI and likes are in great demand by AI models as food for one-time training.&amp;quot; AI platforms know what&amp;nbsp;&amp;nbsp;young engineers don't- it is a platform like SEFI that is&amp;nbsp;&amp;nbsp;the true goldmine of structural engineering knowledge, fed as it has been by hundreds&amp;nbsp;&amp;nbsp;of informed engineers&amp;nbsp;&amp;nbsp;over thousands of hours across&amp;nbsp;&amp;nbsp;than two decades. 
&lt;br&gt;
&lt;br&gt;The human- generated wealth of knowledge such as at SEFI has been consumed without permission- just simply stolen if I may, from across domains of knowledge by AI models. Anthropic AI admitted to consuming millions of paperbooks and once consumed,&amp;nbsp;&amp;nbsp;destroyed physical copies and when copyright lawsuits happened,&amp;nbsp;&amp;nbsp;they offered a measly $3000 per title. Imagine someone buying a book authored by you, and destroying its relevance and its need altogether by offering free knowledge learnt from that book which was your&amp;nbsp;&amp;nbsp;lifetime's work.&amp;nbsp;&amp;nbsp;An&amp;nbsp;&amp;nbsp;AI&amp;nbsp;&amp;nbsp;bot can scrape entire SEFI site within minutes and train it's neural networks while SEFI spent decades to create it. 
&lt;br&gt;
&lt;br&gt;Sites such as SEFI are being overtaken today by&amp;nbsp;&amp;nbsp;AI sites in terms of traffic&amp;nbsp;&amp;nbsp;because users get instant answers from AI rather than engaging with the community. But there is a catch. There will be, in all likelihood, a Kodak moment as they say.&amp;nbsp;&amp;nbsp; The &amp;quot;Knowledge Cannibalization&amp;quot; Argument : A very real phenomenon sometimes called &amp;quot;Model Collapse&amp;quot; or the &amp;quot; *Data Exhaustion&amp;quot; problem is lurking around the corner. 
&lt;br&gt;
&lt;br&gt;There is a BIG RISK: If the community dies, the &amp;quot;training data&amp;quot; for future AI,&amp;nbsp;&amp;nbsp;also dies. AI cannot easily learn new, unpatched software bugs or novel human theories if the forums where those are discussed become ghost towns. AI in structural engineering is dependent on its survival to sites like SEFI. But by&amp;nbsp;&amp;nbsp;trying to making these forums redundant,&amp;nbsp;&amp;nbsp;AI is essentially &amp;quot;eating its own tail.&amp;quot; Without new human interaction, AI models will eventually start training on AI-generated content, which leads to a degradation in quality. New version of these models show no significant improvements over previous one due to data exhaustion... No new human generated knowledge.
&lt;br&gt;
&lt;br&gt;I think it is time that all of us wake up to what's happening and reignite the creative, thinking engineer in us who survived without AI and will now survive, despite it and hand-in-hand with it. 
&lt;br&gt;
&lt;br&gt;warmly,
&lt;br&gt;Alpa&amp;nbsp;&amp;nbsp;Sheth&lt;/span&gt;&lt;br /&gt;

Hello All,
&lt;br&gt;
&lt;br&gt;Do we have to conduct soil chloride and sulphate testing for foundation soil if the land is used for agriculture (coconut grove) for last 40 years using hard water up to 250 ppm? The water is generally low is chlorides (100ppm) and sulphates (50ppm) but I'm not if the soil accumulates chlorides and sulphates over time due to constant irrigation with hardwater, or the periodic monsoon rains wash them away into the soil. 
&lt;br&gt;
&lt;br&gt;I could not find any information on whether a soil chloride test is needed in this case or if this is a real concern at all.
&lt;br&gt;
&lt;br&gt;Your valuable guidance and past experiences is greatly appreciated. Thank you.&lt;/span&gt;&lt;br /&gt;

My dear SEFIans,
&lt;br&gt;
&lt;br&gt;C'mon have a cup of chai and take this 1 minute poll. I promise you, it won't take more than a minute. But let's show the SEFI Community in full strength by participating wholeheartedly. 
&lt;br&gt;The BIS Codes belong to all of us so together we need to participate in giving feedback. It goes a long way to the task of nation-building. 
&lt;br&gt;
&lt;br&gt;With warm regards, 
&lt;br&gt;Alpa Sheth 
&lt;br&gt;
&lt;br&gt;
&lt;br&gt;&lt;/span&gt;&lt;table width="90%" cellspacing="1" cellpadding="3" border="0" align="center"&gt;&lt;tr&gt; 	  &lt;td&gt;&lt;span class="genmed"&gt;&lt;b&gt;admin wrote:&lt;/b&gt;&lt;/span&gt;&lt;/td&gt;	&lt;/tr&gt;	&lt;tr&gt;	  &lt;td class="quote"&gt;&lt;div align="justify"&gt;Hello Sefians,&lt;/div&gt;
&lt;br&gt;&lt;div align="justify"&gt;Hope all is going well and other than the heat, things are good with you!!&lt;/div&gt;
&lt;br&gt;&lt;div align="justify"&gt;We have all been hearing the emphasis on &amp;quot;&lt;span style="font-weight: bold"&gt;Ease of Doing Business&lt;/span&gt;&amp;quot; in our country for a while now. We thought that it would be a good idea, following the same principle, to &lt;span style="font-style: italic"&gt;initiate a conversation&lt;/span&gt; regarding &amp;quot;&lt;span style="font-weight: bold"&gt;Ease of Use of Important BIS Codes in the Practice of Structural Design in India&lt;/span&gt;&amp;quot;&lt;/div&gt;
&lt;br&gt;&lt;div align="justify"&gt;We request you to kindly participate in huge numbers in this &lt;span style="font-weight: bold"&gt;one minute anonymous poll on ease of using BIS codes&lt;/span&gt; at this &lt;span style="font-weight: bold"&gt;&lt;a href="https://forms.gle/Up76mnNSPfmZGQDL7"&gt;link&lt;/a&gt; (Google form)&lt;/span&gt; . We believe that this information will be immensely useful to the code-writers and Bureau of Indian Standards in the formulation of Codes. More importantly, it may show a way forward to BIS for getting feedback from the community before final issue of new or revised Codes for implementation.&lt;/div&gt;
&lt;br&gt;&lt;div align="justify"&gt;Typically BIS issues codes for wide circulation before they are implemented. Potential users of the code are expected to give their feedback on the code. However the number of engineers who give feedback is miniscule. But when the code is implemented, there are loud concerns raised about difficulties in implementing the code, but it may then be a bit late by then or the code is unceremoniously withdrawn which is not a good precedent.&lt;/div&gt;
&lt;br&gt;&lt;div align="justify"&gt;A poll such as the one being conducted will allow engineers to convey their views quickly to the concerned agencies, and in the long run, allow India to have codes which are easy to use and ensure safety and stability of the built environment.&lt;/div&gt;
&lt;br&gt;
&lt;br&gt;&lt;a href="https://sefindia.org/poll"&gt;Participate in the Poll Now&lt;/a&gt;
&lt;br&gt;
&lt;br&gt;&lt;span style="font-weight: bold"&gt;Help Spread the Word&lt;/span&gt;

Hi all,
&lt;br&gt;&amp;nbsp;&amp;nbsp;I have been using Prabhakar sirs Crane Beam Design XLS sheet,
&lt;br&gt;
&lt;br&gt;I found a typical case which I request seniors to clarify
&lt;br&gt;
&lt;br&gt;I have a Girder section which was passing with 12 mm thk web
&lt;br&gt;but the moment i made it 16 mm thk the design fails (in Prabhakar sirs xls),
&lt;br&gt;
&lt;br&gt;unfortunately as Prabhakar sir is no more I cannot ask him to clarify or correct the BUG.
&lt;br&gt;
&lt;br&gt;find attached my detailed explination how and why the design fails
&lt;br&gt;I have made some assumptions, please correct me 
&lt;br&gt;in brief i have used

&lt;br&gt;
&lt;br&gt;i feel there is a Bug in prabhakar sirs program , I know many will not be having the program, but effectively it just calculating beta_b and which Zp&amp;nbsp;&amp;nbsp;has to be taken (Full Zp or Only Zp of Flanges)
&lt;br&gt;
&lt;br&gt;can anyone help me out&lt;/span&gt;&lt;br /&gt;

&lt;br /&gt;&lt;span class="postbody"&gt;
&lt;div align="justify"&gt;Hello Sefians,&lt;/div&gt;
&lt;br&gt;&lt;div align="justify"&gt;Hope all is going well and other than the heat, things are good with you!!&lt;/div&gt;
&lt;br&gt;&lt;div align="justify"&gt;We have all been hearing the emphasis on &amp;quot;&lt;span style="font-weight: bold"&gt;Ease of Doing Business&lt;/span&gt;&amp;quot; in our country for a while now. We thought that it would be a good idea, following the same principle, to &lt;span style="font-style: italic"&gt;initiate a conversation&lt;/span&gt; regarding &amp;quot;&lt;span style="font-weight: bold"&gt;Ease of Use of Important BIS Codes in the Practice of Structural Design in India&lt;/span&gt;&amp;quot;&lt;/div&gt;
&lt;br&gt;&lt;div align="justify"&gt;We request you to kindly participate in huge numbers in this &lt;span style="font-weight: bold"&gt;one minute anonymous poll on ease of using BIS codes&lt;/span&gt; at this &lt;span style="font-weight: bold"&gt;&lt;a href="https://forms.gle/Up76mnNSPfmZGQDL7"&gt;link&lt;/a&gt; (Google form)&lt;/span&gt; . We believe that this information will be immensely useful to the code-writers and Bureau of Indian Standards in the formulation of Codes. More importantly, it may show a way forward to BIS for getting feedback from the community before final issue of new or revised Codes for implementation.&lt;/div&gt;
&lt;br&gt;&lt;div align="justify"&gt;Typically BIS issues codes for wide circulation before they are implemented. Potential users of the code are expected to give their feedback on the code. However the number of engineers who give feedback is miniscule. But when the code is implemented, there are loud concerns raised about difficulties in implementing the code, but it may then be a bit late by then or the code is unceremoniously withdrawn which is not a good precedent.&lt;/div&gt;
&lt;br&gt;&lt;div align="justify"&gt;A poll such as the one being conducted will allow engineers to convey their views quickly to the concerned agencies, and in the long run, allow India to have codes which are easy to use and ensure safety and stability of the built environment.&lt;/div&gt;
&lt;br&gt;
&lt;br&gt;&lt;a href="https://sefindia.org/poll"&gt;Participate in the Poll Now&lt;/a&gt;
