- Abstract
- This study's purpose 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 loading test of 4 full-scale exterior connection specimens to evaluate the effect of column strength and beam depth. All specimens are designed as strong column-weak beam and strong panel zone. They are observed at the peak deformation of each cycles with the unaided eye. 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. Also, K120TG, which is the developed weld metal for 800MPa grade steel, is estimated as good material in case of welding between normal strength steel and high-performance steel through this study.
