ABSTRACT
The conceptual design of wood members was that an axial member was subjected to axial tensile stress or axial compression stress only, and a flexure member was subjected to normal bending stress only. However, the compression force acting on a member tends to buckle a member out of the plane of loading. This buckling occurs in the columns and in the compression flange of the beams unless the compression flange is adequately braced. The chapter presents the detailed designs of flexure members, axially loaded tensile and compression members, and the members subjected to the combined flexure and axial force made of sawn lumber, glued laminated timber, structural composite lumber, and cross-laminated timber. In a member subjected to flexure, compression develops on one side of the section; under compression, lateral stability is an important factor. It could induce a buckling effect that could undermine the moment capacity of the member.
