A W14 x 233 A992 beamcolumn supports the required strength f

A W14 x 233, A992 beam-column supports the required strength forces Pu and Mu as shown. Check the adequacy of this W-shape to carry these forces. Use Table 4-1 for the design strength . The moments shown are about the weak axis, and bracing is provided only at the supports. 480 kips --) 625 k-ft L=24 ft 625 k-ft 480 kips

Solution

effective length of column=24 ft

section is w14x233

per table 4-1, compressive strength of section for effective length of 24 ft=2150 kips

moment capacity of beam about minor axis = 828 kip-ft

from interaction equation, (480/2150)+(8/9)(625/828) = 0.89<1
