Question
Transcribed Image Text:A W24x76, A992 steel is to be used as simply
supported beam to resist a concentrated load at
midspan. The beam will be laterally braced at the
supports and at midspan.
Section Properties (W24x76):
Ag = 14500 mm2
bf = 228 mm
tf = 17.3 mm
tw = 11.2 mm
Sx = 2880 x 103 mm3
Zx = 3280 x 103 mm3
J=1120 x 103 mm4
k = 30 mm
rx = 246 mm
d = 607 mm
Use strength-reduction factor, ø= 0.90
Assuming that the self-weight of the beam may
be neglected, determine the flexural capacity
(kN-m) of the beam for the following cases:
a. Length of beam, L = 3 m.
b. Length of beam, L = 10 m.
c. Length of beam, L = 15 m.
