Abstract

This paper investigates the seismic performance of steel hollow box sections. The test results obtained from the combined load tests were used to define the relationship among member performance, sectional aspect ratios and the load combinations. It was found from the comparisons that the flexural strength of members decreased when the torsion magnitude was increased. It was also observed that the reduction in flexural strength increased when the sectional aspect ratio was increased. An empirical expression for estimating member performance under three-dimensional loads is proposed for design references.
