TBeams are used to support a floor in an industrial building

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

Solution

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
