This paper describes an experimental study that assesses the influences of infill and member slenderness on the performance of earthquake resistant hollow steel brace members. Two series of tests are described. In the first series, hollow and filled specimens were subjected to cyclic axial loading, and their hysteretic responses observed. Eventual failure of the stockier specimens occurred due to tensile rupture after initial fracture caused by local buckling in the post-buckled state. The effect of the infill on this mechanism is described. In the second experimental series, shaking table tests were carried out to determine the influence of the brace parameters on dynamic inelastic response. By normalising the hysteresis loops of the braces obtained from the shake table tests to the yield strength of the steel sections from quasi-static tests, the influence of the infill on the strength of brace is quantified, together with dynamic effects.
