ABSTRACT
This chapter covers the static design of members subjected to axial force either in tension (‘ties’) or in compression (‘struts’). The basic requirement is that the factored resistance should not be less than the tensile or compressive force (action-effect) arising in the member under factored loading. The factored resistance is found by dividing the calculated resistance by the factor gm (Section 5.1.3). There are four possible modes of failure to consider in checking such members:
1. localized failure of the cross-section (Section 9.3); 2. general yielding along the length (Section 9.4); 3. overall column buckling (Section 9.5); 4. overall torsional buckling (Section 9.6).
