Roof Bracings in PEB (How they Work!)

This video explains in detail regarding the force transfer behavior on the roof bracings and how they provide stability along the longitudinal direction.
Bracing force calculation is an essential skill for all steel design engineers and I hope this video add value to your personal learnings.

Ohh man 😮 i found gold on UA-cam. V.informative video

[@parishithjayan]

Thanks..

[@suhailshaikh4706]

Good explanation of concept.
Very few videos are available on youTube with such high quality knowledge.
Thanks for sharing

How bracing behaves at expansion joint location?

[@nageshghadge664]

Superb 🙌

[@parishithjayan]

Thank you

[@ganeshpaudel2972]

Thanks for this amazing video. I had a question - What happens if we do not provide the connecting member at the ridge line in this case, how does the bracings behave? What if we do not provide gable end column, Are roof bracings needed for no gable column case?

[@aakashmistry4222]

Very good explanation about bracing system and it's important but if bracing have reversal stress like sometime compression or tension so what is it slenderness limit we need to consider ?

[@parishithjayan]

Just follow code. As per IS 800, for the strut or bracing member subjected to wind or seismic loads where there is a possibility for the reversal of stresses, need to check the tensile slenderness ratio for 350

@@parishithjayan thank you !!

[@Sarathk460]

For earth quake load. How bracing will behave ??? Bcoz of load reversal

[@parishithjayan]

When the load reversal occurs, the other pair of bracing would become active.

[@ashishsojrani1496]

What will happen if I provide bracing in second last bay

[@parishithjayan]

Nothing will happen.. You need to pass the force through strut tube until it reaches the braced bay properly..

Dear Sir your explanation was awesome. But I have one doubt, how do the first 2 rods will inactive, why don't they take the bracing force and gets buckle (fail's in buckling). And also what about wall bracing, which rods will take the force and which are inactive. Please clarify my doubts..... Thank U Sir.....

[@parishithjayan]

Basically, the rods are slender members which are not intended to take any compression force.
Once the bracing force reaches those points, they try to push the rod and since they are slender, they can't withstand this force or they can't transfer this force, so they buckle away means losing its capacity to transfer the bracing force through compression.
Then the force tries to find the new path to reach bottom. So it travels along the line of action, and once it reaches the second rafter, the alternate pair of brace rods gets activated and resist the load through tension.
The same for wall bracings as well.. go through the video once again and try to make a simple bracing model in STAAD and study the behaviour to understand the concept.
