How do structures carry wind and seismic loads? An Intro to Lateral Force Resisting Systems

Buildings carry lateral (i.e., horizontal) loads through lateral force resisting systems. This video introduces the three most common systems:
(1) Braced frames
(2) Moment frames
(3) Shear walls
The lateral force resisting system does not need to cover the entire structural system, but lateral loads do need to be able to transfer from their point of application to the LFRS.

Amazing video professor, thank you for preparing it.

[@coralplanet9025]

Very simple and clear. Excellent presentation

[@StructuresProfH]

Thank you!

[@bunnuakhil2920]

well demonstrated. Enjoyed it.

[@srinivasan632]

Simple narration about significant structural concept.....

[@civilengineeringwitharas4776]

I can say I had never seen like your explanation before.
Thanks in advance.

[@StructuresProfH]

Happy to help!

[@clingclingwawaw]

will you please explain about steel structure for house roof?

[@samueltunji7120]

Hi. Thanks for the teaching. I will like to ask how many braced bay can be introduce in a structure. Also, what is the governing factors in determining the no of braced bays

[@StructuresProfH]

Hi Samuel,
Great question. I don't have any governing rules for finding the number of braces. You can put as many braced bays into your structure as you can fit, but that doesn't mean it's a good idea. On the plus side, more braces means less load per brace. On the minus side, more braces equals more cost (especially in their connections!) and generally less efficiency. You have to find a balance here. Furthermore, you may have architectural constraints that limit you from bracing certain bays.
So as with most things in engineering and life, it depends on the particular costs, benefits, and constraints for your project.

[@sashajohnson9041]

This is a great explanation. I should buy some K'Nex. Do you have a kit you recommend?

[@StructuresProfH]

Hey Sasha,
I recommend the K’nex 100 model set. It’s usually about $50 on Amazon, and has probably the best mixture of different sized rods for free building.

[@edgarprotsko1558]

Can we pin cross cections in the center to each other or they must be separeted like in this example ?

[@StructuresProfH]

Either way will work. Often the cross braces will be pinned in the center.

[@edgarprotsko1558]

Thanx sir @@StructuresProfH
