1. Compute the load on column B3 contributed by this floor if the floor live load is 150 psf. (Consider floor live-load reductions following provisions ASCE 7-16 as appropriate) Assume this is the uppermost floor in a multistory office building. Assume it has a one-way slab behavior. (2 points) 40ft

Solution

Since the live load exceeds 100 psf, it is not permitted to do live load reduction per ASCE 7-16.

Tributary width of column B3=(40/2)+(40/2)=40\'

Tributary length of column B3=(35/2)+(35/2)=35\'

Therefore, tributary area of column = 40*35=1400 sq ft

Load on column B3= 150*1400/1000=210 kips
