Question
T-Beams are used to support a floor in an industrial building. The floor is used for product storage so it must be designed for a heavy 600 psf. The floor must also support a superimposed dead load of 20 psf (in addition to the self-weight of the beams and slab. The layout of the beams and slabs is shown below. The beams span 30’-0” and are spaced at 4’-0” center to center. The slab is 3” thick. The concrete compressive strength is f’c = 3000 psi and the steel yield strength is fy = 60 ksi. The concrete is an interior exposure (not exposed to weather) and the reinforcing steel will be enclosed in #3 stirrups.
What is the uniform live load per foot along the length of the beam?
2400 lb/ft
1800 lb/ft
2000 lb/ft
1200 lb/ft
2400 lb/ft
1800 lb/ft
2000 lb/ft
1200 lb/ft

Question : What is What is the uniform live load per foot along the length of the beam?
Given
Live Load=600psf
The tributary width of central T beam=4 ft
Therefore Uniform Live load per foot along the length of beam is=600x4=2400 lb/ft
