Question
The rectangular steel frame shown is to support a footbridge in a chemical plant. The ends
of the bridge are supported on rollers, so the bridge is permitted to sway (unbraced frame).
All members are oriented with their webs in the plane of the frame (or such that bending
will occur about the strong axis). All columns are assumed to be adequately braced in the
weak direction. All beams are W16x50. Assume t = 1.0 (elastic behavior). Determine the
design compressive strength of column FB (W8x48). Use the LRFD Method.
