Score 4. A W12x53 column of A36 steel supports a vertical load of 40kips at an eccentricity of 12 in. with respect to each axis. The length is 12 ft, and K=1.0 with respect to both axes. Determine whether the member is adequate. For the W12×53: A: = 15.6 in.² Sx = 70.6 in.³ Sy = 19.2 in.³ = 5.23 in. ry = 2.48 in. F"= 54.1ksi Lc = 10.6 ft Lu = 22.0 ft P fa = ²₁₂ fbx = Mx fby = Myy 2 > A Sx Fbx=0.60Fy, Fby = 0.75Fy when <0.15 fa Fa fa+ fbx+ Fa Fbx fby <1.0 F by
