圆管柱-H型钢梁3种不同形式节点的抗震性能研究

Seismic Performance Research in Three Different Forms of Round The String-H Steel Beam Node

通过运用ABAQUS有限元软件对中柱、边柱、角柱3种不同形式的圆管柱-H型钢梁连接点,进行低周往复荷载的加载,研究3种不同节点抗震性能的优劣。采用应力云图、滞回曲线、骨架曲线、延性系数、耗能能力、刚度退化以及强度退化等抗震性能指标分析其抗震性能。

The different seismic performance of three different nodes is studied by using the finite element software ABAQUS in three different forms（middle column, side column and corner column） of round pipe string-H type steel beam connection point, for loading of low cycle loading. The seismic performance is analyzed through several seismic performance index such as the stress nephogram, hysteresis curves, skeleton curves, ductility, energy dissipation, stiffness degradation and strength degradation.
