Question

Could you please use AISC steel manual for the parts needed? 15th edition

2. The frame shown in the figure below is unbraced, and bending is about the x-axis of all members. All beams are W16 x 40. Column BC is supported in the weak direction (i.e 2 direction perpendicular to the plane of the frame) at mid height and it is assumed pinned at both ends in this direction (i.e. Ky=1) Assuming that all columns are rectangular HSS 14x6x5/8, determine the effective a. length factor Ks for column BC. Do not consider the stiffness reduction factor b. Ignoring the shape assumed for columns in part a, select the lightest Rectangular HSS shape for column BC to sustain a factored compressive load of 500 kips. Assume K is equal to the value found in part a, F 50 ksi, and Ky 1. (You may use table 4-3) 20 20" C 13 13' A 77
