live load reduction
live load reduction
(OP)
What I meant is hypothetically if I have 10 floors. On global design I use 100 psf on all 10 floors which
I find excessive as there cant be full of live load on 10 floors at the same time.
Is there anywhere in the code that says on Global design I only need 2 floors or whatever full of
Live load at a time.

Therefore, the code is making some of the same assumptions you are that not all areas will be loaded to the max at the same time.

I never apply live load reduction for floor design but the foundations and lower columns in a 10-story building would receive the 50% reduction. This reduction would gradually reduce (less than 50% live load reduction) for the columns on the higher levels.
There can be the design live load on the 10 floors all at the same time, it is just statisically unlikely.
