Another thing that is often missed with perforated shear walls is the requirement of 4.3.6.1.3 where it says, "each end of each perforated shear wall SEGMENT shall be designed for a compression force, C, in each segment." So you aren't only designing for a compression chord at the end of the wall, but at the end of each segment.
Just a heads up everyone - when the diaphragm/shear wall capacity tables for wind and seismic were unified in SDPWS 2021, they actually changed the stress reduction factors to get you to ASD level capacities. the stress reduction factor of 2.0 is only applicable for wind, and it's now 2.8 for seismic. Kestava, thanks so much for these vids, they're such a great resource and are so expansive and offer a great window into the actual industry side of consulting structural engineering. I'm working not far from you in Washington and these sorts of videos are so good to throw at new grad engineers to send them in the right direction
Great video - I think I suggested this as a video and you definitely delivered! This will be very useful for people studying for the SE since it is listed as a topic. As a bridge guy, I had to skip over this topic during my studies.
they dont get a lot of capacity but are great for smaller structures for sure! everyone just seems to do solid walls and run with that for ease and time. a lil spreadsheet for these walls would be nice to have in the back pocket!
Does the Li value apply only to walls with doors or also walls with windows? I try my best not to include doors in shear walls due to the discontinuity of the bottom plate

Maybe one day ill have the courage to do a bridge example Pavan hahaha
hey kestava, weeee neeed concrete stuff for your followers elsewhere in the world.
great stuff as always.
I hear you! ive got some concrete lined up that I think youll enjoy!
Great video, as always! Thank you.
These are often overlooked! Great video.

If you're new - consider subbing and join the Kestava Engineering Team 😎
or dont 😭
@@Kestava_Engineering And miss out on all this? Defintiely not! XD
lets go Quantum!
Another great video! Thank you Rich!
Glad you enjoyed it! happy to be back providing these videos!
Very good video Engineer thank you

Great video ! Thank you very much ! Could you make a video example of composite beam with concrete slab on steel deck?
Great video! Can you provide a wood FTAO design example in another video?
god those take a bit of time to calc out. let me look into it and see if i can get a problem together!
That would be much appreciated! Keep up the great work!!
Sir how much do you earn now? Plz reply. Thanks a lot.
Im doing an updated video and short on this soon! keep a lookout for it
