Question
Arectangular concrete hollow section simply supported beam shown below
have the following dimensions: b= 10-inch, w = 2 inches and h = 18 inches
and spans 14 ft. The section should carry its own weight and imposed a
dead load of 150 Ib/ft and a live load of 50 lb/ft. If the young's modulus is
10.2 x 10° psi and the density of concrete is 150 Ib/ft³, calculate the:
1. Permissible bending stress if the concrete strain is 0.003
2. The moment resistance of the beam
3. The maximum bending moment
b
w
