A cantilever beam having a 4m span carries a uniformly distributed load throughout its length. The beam is A36 steel with yield strength Fy = 248 MPa. The beam is not restrained against lateral buckling. The beam is W 21 by 62 steel shape, whose relevant properties are shown below: r = 0.053 m d = 0.533 m bf = 0.210 m tf = 0.016 m S = 0.002077 m3 Given this condition, solve for the allowable flexural stress in the compression flange. Use Cb = 1 as should be taken conservatively

Transcribed Image Text:A cantilever beam having a 4m span carries a uniformly distributed load throughout its length. The beam is A36 steel with yield strength Fy =
248 MPa. The beam is not restrained against lateral buckling. The beam is W 21 by 62 steel shape, whose relevant properties are shown
below:
r = 0.053 m
d = 0.533 m
bf = 0.210 m
tf = 0.016 m
S=0.002077 m³
Given this condition, solve for the allowable flexural stress in the compression flange. Use Cb = 1 as should be taken conservatively.
