Great video! Thanks for sharing. I really like your format and style. I think you do a good job of explaining the technical stuff and also peppering in some lessons learned, so thanks for that!
Is there an error in the simplification? Being that Em and t located in the denominator when going over to the other side of the equation would have to multiply by Delta? Although that in the end since it’s unitary then it doesn’t end up making a difference I just wanted to clarify this just in case or am I missing something?
6:33 Hi Kestävä, Thank you for all of the videos that you have done so far. They are a great review for my job. I wanted to ask you though about right here. And why won't it not be just T/1 on the other side because of multiplying it on both ends by T/1 to cancel T out on the denominator on the right.
This is a really interesting topic that I have gotten mixed reviews on. I am digging into this exact topic for a future video. As a lot of engineering comes down to... it depends! you're asking the right questions!
Makes sense to use cantilever on top story since it is free. I’ve noticed for rigid diaphragm wall shear loads, it doesn’t really matter which boundary conditions you use since the stiffness ratios come out the same and hence shear load distribution the same. Like most engineering problems, reality is probably between both models.

I appreciate that!
Not that it affects the answer because it's 1, but just wanna make sure the Em moved over ends up with deflection x Em instead of divided by it?
I came here to say this also

How do choose between the cantilever and fixed-fixed rigidity equations? Does it depend on the material/stiffness of the diaphragm?
I would assume the fixed-fixed condition for all stories except the topmost story in a structure and assume cantilever for the topmost story.

bingo @arbaz28!
