ABSTRACT
During the past three decades, an increasing amount of experimental and theoretical studies on the performance of H-section beam-columns has been available. Starting with the early work of Nakashima, the research team examined the monotonic behavior of H-section steel members composed of compact elements thoroughly by test, numerical and statistical analysis. Based on this, approaches to assess the key measures of member performance, strength and ductility, have been developed [2-5]. Some previous studies of Chen [6-7] focused on the hysteretic behavior of H-section members, including both SC-S members and compact members. The research team has sought out the effects of the width-to-thickness ratio of elements as well as the axial compression ratio on hysteretic behavior of SC-S members and put forward design approaches.
