摘要
通过对设置普通支撑和屈曲约束支撑两种钢框架结构的动力弹塑性分析,统计在不同地震波激励下的层间位移角峰值、底部剪力最大值、构件损伤等级及支撑构件的内力-位移关系滞回曲线等计算结果,分析两种支撑钢结构在罕遇地震作用时的承载能力和耗能作用。
By analysis of dynamic elastic-plastic on steel frame structure with general brace and buckling restrained brace, the maximum story drift ratio, the maximum value of bottom shear force, component damage level and hysteresis curve of two kinds of braces under different seismic wave excitation were calculated. Through the calculation results, two kinds of braced steel frame structure action bearing capacity and energy consumption under rarely occurred earthquake was analyzed.
