The rigid frame shown is unbraced. The members are oriented so that bending is about the
strong axis. Support conditions in the direction perpendicular to the plane of the frame are such
that Ky= 1.0. The beams are W16 x 57, and the columns are W10 x 100. A992 steel (E= 350
MPa and Fy= 450 MPa) is used. The axial compressive service DL= 400 KN, and the axial
compressive service LL= 490 KN. Determine the allowable axial compressive design strength of
column AB. Use the stiffness reduction factor if applicable. Use ASD.
