My dear SEFIans,

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.
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.

With warm regards,
Alpa Sheth

Hello Sefians,

Hope all is going well and other than the heat, things are good with you!!

We have all been hearing the emphasis on "Ease of Doing Business" in our country for a while now. We thought that it would be a good idea, following the same principle, to initiate a conversation regarding "Ease of Use of Important BIS Codes in the Practice of Structural Design in India"

We request you to kindly participate in huge numbers in this one minute anonymous poll on ease of using BIS codes at this link (Google form) . 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.

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about difficulties in implementing the code, but it may then be a bit late by then or the code is unceremoniously withdrawn which is not a good precedent.

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.

SEFI General Discussion :: Crane Beam Design Web thk increase is failing the section

Hi all,
  I have been using Prabhakar sirs Crane Beam Design XLS sheet,

I found a typical case which I request seniors to clarify

I have a Girder section which was passing with 12 mm thk web
but the moment i made it 16 mm thk the design fails (in Prabhakar sirs xls),

unfortunately as Prabhakar sir is no more I cannot ask him to clarify or correct the BUG.

find attached my detailed explination how and why the design fails
I have made some assumptions, please correct me
in brief i have used
Clause  Cl. 8.4.2.1   d/tw > 67�ε  hence make the section semi compact
or
Table 2
Web is Plastic (d/tw ≤ 84�ε )  which makes it plastic

for tw = 16:
Zp usedβ_bMdz formulaMdz (kNm)

(Cl. 8.4.2.1)	Zp_fl = 6 994	Ze/Zp = 1.63	Ze � fbd	2 055
(Table 2 only)	Zp_full = 12 037	1.0	Zp_full � fbd	2 170
XLS ( the bug)	Zp_fl = 6 994	1.0 ← wrong	1.0 � Zp_fl � fbd	1 261

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 has to be taken (Full Zp or Only Zp of Flanges)

can anyone help me out
