Implementation of IS800:2007 code in STAAD - Part 1: Stability Analysis & Tension Member Design

[@simpslayer7664]

I suggest these videos to all the GET'S who have joined us.... Thanks for these.....We could never do it better ourselves....

[@surojit_ghosh]

Thanks for your feedback, nice to hear this. I tried my best to discuss the concept from the basics, rather than just discussing about the clauses and steps. I hope you and your colleagues will enjoy the upcoming series on steel connection design and PEB structure.

Hello is there any book which explained the complete step by step design in staad pro using IS 800 codal provision

Thanks

Hello sir, Thank you for sharing knowledge, how to solve this , at 21.17 min Note: 122. if any floor diapharam present in the modal ........ ???

[@surojit_ghosh]

It's just a note to inform the user about the command sequence. If any floor diaphragm is present in the model, then wind load must be defined after the diaphragm command. Else wind load generation is not successful during analysis. If a floor diaphragm is defined in the model along with wind load, you need to check the command sequence from the input editor. There is no way (except SET command) to eliminate this note.

What is the slenderness limit considered for member truss elements? Should it be 250 or 300

[@surojit_ghosh]

That depends. In Table 3 of IS800:2007, nothing specific to truss member is mentioned. For tie or bracing members of a truss ineffective due to stress reversal, you can consider the limit as 350. For top or bottom chord members which are subjected to compressive force due to gravity load, it is better to consider the slenderness limit as 180 for compression and 400 in tension. Just one additional information. You can consider slenderness ratio as 250 or even bypass the slenderness check, but higher actual slenderness ratio will always affect the compression capacity as well as the overall capacity of the section under combined load.
