Question

A W21 x 50 spans 11.0 m on a simple span. The compression flange is laterally supported at the third points. A36 Steel is used.

Properties of W21 x 50 section

A = 9,484 mm2                bf = 165.9 mm                 d = 529.1 mm                    tf = 13.6 mm

tw = 9.7 mm                      Ix = 409.57 x 106mm4    Iy = 10.36 x 106mm4        w = 0.73 kN/m

Sx = 1548.58 x 103mm3 Sy = 125.20 x 103mm3

 

a. Determine the allowable bending stress of this beam.

b. Determine the allowable superimposed uniformly distributed load be place on this beam.
