A short column made of structural steel ASTM A36 standard wide-flange section is used to support the floor beam of a building as shown in the figure. Each floor beam (A and B) transmits a force F of 50 kips to the column through standard steel angle L 4x4x1/2. The angles have lengths equal to the flange width of the W-shape column, and they are welded to it. a. Use the AISC standards, select the lightest wide-flange shape that will support the loads. b. Calculate the shear stress in the welds between the angles and the column. C. Calculate the bearing stress on the angles. d. Instead of welding, the angles are bolted to the column flanges using two bolts per flange, each is 1 "diameter and made from SAE 1040 CD. i. Calculate the bearing stress in the bolts. Is it acceptable? 4 ii. Calculate the shear stress in the bolts. Is it acceptable if the load is static. If not determine the minimum acceptable bolt diameter. T B
