Introduction

Timber sections are commonly used in construction as axially loaded members or as members subjected to combined axial and bending actions. Members of a truss, posts or columns, vertical wall studs and bracing elements are typical examples. Some examples are shown in Figure 5.1.

This chapter covers the design of straight solid timber or wood-based structural products of uniform cross-section in which the grain runs essentially parallel to the member lengths and the members are subjected to the effects of axial compression or tension or combined axial and flexural actions. The design of glued-laminated section columns and of built-up columns is covered in Chapters 6 and 8 respectively.

The general information in Section 4.3 is relevant to the content of this chapter.
