Dear Er someshwar ganti

Copy paste from other applications such as word/excel will not work. Plain Text copy paste from Note Pad etc may work.

When reading content from clipboard and it is non plain text (html etc) , it has known issues of losing content in some cases.

Work around: Try putting post in notepad, paste in forum use preview button to see if its losing it as a test".

We will see if there be a resolution to this issue.

Regards

Admin

Hello everyone,

We are currently planning the development of an internal structural analysis and design software platform and are looking to connect with experienced application developers or firms with relevant expertise.
The intended software will cover the full engineering workflow, including:

2D/3D modelling
Load definition and combination generation
Structural analysis (integration with an established solver)
Code-based design verification (Eurocodes and other standards)
Product-based validation logic
Reporting, BOQ generation, and BIM interoperability

The application will be used internally by structural engineers and must support professional-grade engineering calculations and modular system architecture.
We are particularly interested in developers or teams who have experience in:

Structural analysis software development
Integration with third-party calculation engines
Parametric modelling environments
Engineering-grade desktop or hybrid (desktop/cloud) applications
BIM / IFC data exchange

If anyone can recommend experienced developers, firms, or share relevant contacts, we would greatly appreciate it.

I think LOAD COMBINATION OF DL + WL  SHALL BE

(0.75 DL  + WL)

IT SEEMS MIS PRINT / OR ERRATA

PLEASE SEE ANY CORRIGENDUM ISSUED TO THIS CODE FOR THIS CORRECTION

JUST MY VIEW

FULL WIND LOAD NEED TO BE TAKEN WITH 75% DL TO ACCOUNT FOR ERRORS/ ASSUMPTIONS IN DL COMPUTATIONS

ALSO WHEN LOAD COMBINATION S
(DL + LL) 1.0  IS OK

BUT

LOAD COMBINATION (  DL+LL+WL) MAY NOT OCCUR SINCE DURING HEAVY STORMS ON SLOPING ROOF - NO QUESTION OF LL PRESENCE,, KINDLY SEE Steel STRUCTURES BOOKS BY EMINENT AUTHORS

I FEEL IF SUCH COMBINE IS ASKED FOR IN CODE -
IT HAS TO BE  ( DL + LL  +WL) 0.75  AS POSSIBILITY OF THREE LOADS COMBINE IS RAREST OF RARE

PLESE CHECK

JUST MY OPINION BASED ON LOGIC PLUS OLD STEEL STRS DESIGN BOOKS

In continuation to the earlier post on this subject -

Along with Professor HS Rai saheb , Authour UH Varyani Sir , Er Akash Solanki s role in creating Digital version of these rare Books is very encouraging to the Structural and Civil Engg Fraternity.

Converting Varyani Sir's Treasures from Hard to Soft Version is not easy Task and requires great efforts in terms of DEDICATION TO THE SUBJECT, KNOWLEDGE , DISCIPLINE, AND ATTITUDE OF SERVICE TO SOCIETY. I think Prif HS Rai Saheb rightly pointed out the Er Akash Solanki 's contribution for great job done.

Salutation to all three great Stalwarts,, with best regards ,,

Great efforts from Professor HS Rai saheb, for putting three books out of Five/six. Rai saheb is doing very selfless service to the Structural Engineering Community, thus indirectly helping the Civil Society at large in creating Safe Structures . His digitalization these Rare Books of immense Technical Values is highly praiseworthy and rightly acknowledged by Respected Author himself.

My standing salutation to Sri H S Rai saheb for his commendable work. May please keep it up.

Also , many thanks to Varyani Sir for Free publication of on line Versions of his books, some of which are not available in Hard form.

Best regards to Rai saheb and UH Varyani Sir,

Thank you Er. Vikran Jeet Ji for your kind words. If you considered me like that then that is your greatness, I don't deserve that much. All credit goes to original author U H Varyani Sir and then efforts done by Er. Akash Solanki .

Thank you Er. Akash Solanki for posting these books as soft copy.

This relieved me from the great gilt of not able to preserve / keep links / files up (due to unfortunate harddisk crash, data from which could not retrieved).

You did a great job.

Thank you once again.

Posted: Tue Feb 17, 2026 8:00 pm (GMT 0)

Hello everyone,

With the new IS code in circulation and practice, there�s a lot to learn and adapt.

It�s a great opportunity for future discussions in this forum. To better understand the code and make practical, reasonable decisions for robust structures, I�d like to raise a few queries.

My question concerns the significant difference between horizontal and vertical base shear values obtained using the new codal guidelines. While there�s a noticeable increase in horizontal base shear forces, the vertical base shear values seem much higher than previously considered in design. I�ve tried to present my query concisely. Kindly go through the list and tables (attachment) provided below.

1. Base Shear in Vertical Direction
o     The code guides us to use a time period value Tv in calculating vertical base shear. As per code this Tv is to be obtained from modal analysis.
o     Using Tv value from the modal analysis (0.4-0.5 seconds) generates a vertical force of 234,123.76 kN which is approximately 50% of the seismic weight.(too high & unrealistic based on IS 1893:2025)
o     Further the code talks about the calculation of Delta V, Tv, on which more information is needed.
o     More clarity is desired about the formulation of Av & its base shear evaluation.
o     In contrast, the design horizontal base shear is only about 4% of the seismic weight.

2. Comparison Between Old and New Code Provisions

o     The old code (IS 1893:2016 Part I) specified vertical base shear estimation (Z-direction ) using the highest scale factor of earthquake forces in X and Y directions, rather than a direct formula. This approach typically resulted in vertical forces that were only a fraction of the seismic weight .
o     The new code (IS 1893:2025 Part I) now prescribes a direct formula of Av*W

3. Trial Using Old Code Practice

o     For case study purpose, we applied the old practice of vertical base shear calculation to the current ETABS model, while keeping horizontal base shear as per the new code. This yielded vertical base shear values of around 4,000 kN .
o     These values appear more reasonable compared to the calculated vertical base shear which is 2,34,123 kN

Clarification Requested: Seeking your guidance on the following:
�     How best to define and adopt vertical earthquake forces so that the results remain reasonable and physically consistent.
�     The correct interpretation of codal provisions in IS 1893:2025 for vertical base shear, particularly regarding the choice of Tv and seismic weight (W).
�     Recommended approach to ensure compliance with the new code while avoiding unrealistically high vertical forces.

Please let us know your inputs on the same & it would be appreciated if BIS and SEFI members can clear the ambiguity that exists in the code.

Hi All:
As you are aware the revised IS 1893-1 and new IS 1893-5 have been published in November. I think SEFI is a perfect platform to discuss these codes.

Let us share insightful and well thought out comments on these codes. What did you like in them and what has been a source of concern or frustration? What do you find illogical/impractical or difficult to implement? What are the changes you would like to see and why? I would especially like Senior SEFI members to jump in, and would also love to hear from our young fresh voices.

Our discussions will go a long way in helping to improve the codes. I am sure that an Amendment or a Revision will be in the offing in the near future, so now is the time to discuss. We can then send the comments to the Bureau of Indian Standards from SEFI in a consolidated document.

As a start, I would like to share the following youtube videos on the codes by Prof Manish Shrikhande, IIT Roorkee. I think you may find them particularly enlightening in their discussion of Probabilistic Seismic Hazard Assessment even though the videos may be generally critical of the revisions. I think constructive criticism goes a long way in improving things, but let us pl be polite in our discussions.
