Research Abstract

This study is consideration of dynamic hysteretic characteristics based on the dynamic cyclic loading tests of structural steel and evaluation of strain-rate effect in seismic performance of steel buildings. First, I have conducted a series of dynamic cyclic loading test of steel which popularly used as hysteretic damper, column, and beam. Regardless of steel kinds, yield strength glowed up when strain-rate was increased. However, the glow of strength was stopped in large plastic deformation. Strain-rate was affected only several cycles after loading have started. Second, I made a database of steel performances affected strain-rate base on previous experimental studies.
