Abstract

The unprecedented damage to steel structures during the Hyogo-ken Nanbu Earthquake not only prompted the revision of the Japanese seismic code but also emphasized the need for a comprehensive understanding of seismic response, which in reality is complex and multi-directional, as opposed to the conventionally assumed uni-directional approach. Thus, this experimental study investigated the effects of multi-directional load histories on the response of tubular columns widely used in the construction of elevated highways and building structures. Test results indicate that, in comparison with uniaxial displacement paths, multi-directional displacement patterns lead to significant degradation of stiffness, strength and ductility of tubular columns.
