고강도강 기둥을 적용한 WUF-W 접합부의 반복하중 실험

Abstract

The purpose of this study is to evaluate the seismic performance of Welded Unreinforced Flange-Welded Web connections with the column composed of high-performance steel. The study involved the inelastic cyclic testing of 4 full-scale connection specimens to evaluate the effect of column strength and beam depth. The specimens were designed to strong column-weak beam and balanced panel zone. 3 of 4 specimens including 2 specimens consisted of high-performance steel column are achieved total story drift of 0.04 rad or more prior to failure. The test results showed that ductility capacity of connections with high-performance steel column is sufficient in light of current AISC seismic design. Energy dissipation in specimens consisting of high-performance steel column is less than those of normal strength steel column.
