Question

Q3 (8marks) The frame shown in the figure is un- braced (Sideway Uninhibited) and bending about the x-axis of all columns are W12x58. And we found that Gg-G-1.22 ing the assumptions of alignment charts are met. All girders are W16x40, and 15f Using the alignment charts, determine the effective length factor K, for the columns AB and BC. Determine the design axial load for the column BC. . . a. Use AISC Equation E3-2 or E3-3. b. Use Table 4-1 from the Manual (F 50ksi. E- 29000ksi ) . Check the section for local buckling Width-thickness ratio for web and flange)
