Abstract

Concentrically braced frames are commonly employed as lateral load resisting structures. Their response largely depends on the behaviour of the braces, which are the key energy dissipative zones. Although steel braces under cyclic axial loading have been studied experimentally, there is a need for further assessment focusing on quantifying failure. This paper describes the development of sophisticated finite element models of hollow sections subjected to cyclic axial loading. Also, an accurate, though simple method to predict fracture life was adopted. The effects of initial imperfections and strain hardening were taken into consideration and the models were validated against data from several test programmes. A parametric study was carried out to study the effect of member and cross-section slendernesses on the performance of the braces. The results were compared with the results from other experimental programmes and design specifications.
