Lateral Load Path in Steel Building 

Thank you

Very thoughtful videos sir... kindly continue this

Very helpfull explaination.. thank you so much.. 🙏🏻🙏🏻🙏🏻

well explained.. thank you sir.

Very Informative... Thank You....

very nicely explained..thanks

Thank You for the informative videos. Do you also make detailed construction drawings for companies who wants to build/weld the steel constructions?

Hi Sir, you said if the major axis is designed as moment connection, when we consider the longitudinal force, we can only design it as pin connection at the minor axis side, I.e. only axial force will be transferred to the bracing. Could we also design it as moment connection in the minor axis side or we don't do it just because it is not effective for taking the moment in minor axis？ Thank you！

Can you have a braced frame system in both directions (transverse and longitudinal)?

Sir when we assign a rod section for bracing members so then why we are assign only as a compression not a tension members ??

Tonmoy - the lateral action would go along the strut (which is purposely designed for the comp force) to the very last column then the force would engage the vertical diagonal bracing as a tensile component (which is good in tension). Don't think it would be as efficient to have the vertical bracing in compression as you explained .... and technically it's not a right of doing things. Same deal with the struts in the roof plane, where the lateral force would travel along the struts in comp and then engage the bracing in tension until it gets to the corner of the building then again travels along the vertical bracing in the form of tensile force then resolved at the footing level.

How the lateral loads will be transferred if there is no plan bracing?

Sir i have asked for Ly, unt, unb etc., Parameters long back ago... kindly do a video on that please

Why plan bracing is provided at ends.

but, not all SB intersect a bracing, not in your last sketch at least

Please use different color pen.can not see the cursor where it's moving

Your description of lateral load transfer around timestamp (5:48) is not correct. If you consider a cross bracing (X-brace), the predominant force transfer would be the tensile behavior. Please do correct it. And once again, please do make videos only on your area of expertise. Kindly check the structural behavior with a proper analysis model, before you teach someone else.
