Built-up column 10 m long consists of W350x90 with two 12 mm thick plates welded to form a box section 250 mm as shown. The colhumm is fixed at both ends and braced (assume hinged) at the midheight about the weak axis. Assume F-248MPA. Use the theoretical values for the effective length factors. Compute: a. Effective slenderness ratio with respect to x-axis. b. Effective slenderness ratio with respect to y-axis. c. Compute the axial load capacity. 350 mm X Properties of W350x90 be = 250 mm tr= 16.40 mm d = 350 mm tw=9.50 mm I = 266 x 10° mnm Iy = 44.54 x 10° mmt A = 11.550 mm

Question
Built-up column 10 m long consists of W350x90 with two 12 mm thick plates welded to form a box section 250 mm as shown. The columm is fixed at both ends and braced (assume hinged) at the midheight about the weak axis. Assume Fy-248MPA. Use the theoretical values for the effective length factors. Compute: a. Effective slenderness ratio with respect to x-axis. b. Effective slenderness ratio with respect to y-axis. c. Compute the axial load capacity. 350 mm X Properties of W350x90 be = 250 mm tr= 16.40 mm d= 350 mm tw=9.50 mm I = 266 x 10° mm Iy = 44.54 x 10° mm* A = 11.550 mm
