钢管混凝土延性柱耗能器抗震性能试验研究

An Experimental Study on Seismic Performances of Concrete-filled Steel Tubular Ductility Column Damper

通过钢管混凝土延性柱耗能器在低周反复水平荷载作用下的试验,研究了圆形截面和矩形截面钢管混凝土延性柱耗能器的抗震性能,得到了钢管混凝土延性柱耗能器的破坏形态、滞回特性、延性系数、等效粘滞阻尼系数等参数。结果表明,钢管混凝土延性柱耗能器具有良好的消耗地震能量的能力。

Based on experiments of two groups of CFT ductility dampers under lateral cyclic loads with vertical stable loads,seismic behavior of concrete filled quadrate tubes columns,as well as circular ones,are proceeded.Behaviors include failure pattern,hysteresis characteristic,coefficient of ductility and equivalent damper.The study results indicate that damper made of concrete filled steel tube has good performances of dissipating energy in case of earthquake.
