AW14×142 is used as a column having a length of 9m 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 5.4m above the bottom support. It is assumed to be pinned connected at the bracing point. Using A36 steel F, = 248MPA and the NSCP Specifications.
