A W 14 x 142 is used as a column having a length of 9 m. long. It is hinged at the upper end and fixed at the lower end but there is a lateral bracing perpendicular to the minor axis of the W section at a point 5.4 m. above the bottom support. It is I assumed to be pinned connected at the bracing point. Using A 36 steel Fy = 248 MPa and the NSCP Specifications. Es = 200000 MPa. 0 Compute the slenderness ratio. Compute the allowable axial stress. * Compute the capacity of the column section. = = hinged у = W 14 x 142 Lateral support Properties of W 14 x 142 A = 26967.69 mm d = 374.65 mm by= 393.70 mm ty= 27.00 mm tw = 17.27 mm 3.6m 1x = 695.11 x 106 mm ly = 274.71 x 106 mm Sy = 3719.86 x 103 mm3 Sy = 1396.18 x 103 mm3 rx = 160.53 mm Py = 100.84 mm 5.4m Assume Ky = 0.80'for 9 m. length Ky = 1.9 for the 3.6 m. length Ky = 0.80 for the 5.4 m. length x Х = Х Lateral support (assume to be pinned connected) fixed
