Question

Situation 6: A W18x97 simply supported beam carries a uniformly distributed load. The properties of the section relevant to the problem are as follow: Use A50 steel and Cb = 1.14
d = 472 mm
bf = 282 mm
tf = 22.1 mm
tw = 13.6 mm
kdes=32.3 mm
ry = 67.3 mm
lx = 728 x 10^6 mm^4
ly = 83.7 x 10^6 mm^4
Sx= 3080 x 10^3 mm^3
Zx =3460 x 10^3 mm^3 
J = 2440 x 10^3 mm^3
Cw= 4240 x 10^9 mm^6 
Which of the following nearly gives the Design Strength Moment (LRFD) if the span of the beam is 9 m?
a) 666 kN-m
b) 367 kN-m
c) 781 kN-m
d) 381 kN-m
