Abstract
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.
