Question

A beam is built-up from the following A36 plates: 420x20 plates as flanges and 500x20 plate as web. The beam is simply-supported and subjected to concentrated load at midspan. The member is laterally supported at the ends only.

Limiting L Values:
L_p = 4.762 m
L_r = 11.810 m

Section Properties:
A = 27200 mm²
I_x = 1 370 026 667 mm⁴
S_x = 5 269 333.333 mm³
r_x = 224.430 mm
I_y = 246 960 000 mm⁴
S_y = 1 176 000 mm³
r_y = 95.286 mm
J = 3 626 666.667 mm⁴
c = 1.0 (doubly symmetric I-shaped member)
r_ts = 110.753 mm
h_o = 520 mm

Compute for the ultimate moment capacity (in kN-m) of the beam if it spans 4m.
