钢-混凝土组合框架结构恢复力模型研究
|
摘要
对8榀由钢-混凝土组合梁和钢管混凝土柱构成的组合框架结构进行水平低周反复荷载试验。试件考虑柱轴压比、梁柱线刚度比和长细比3个设计参数的变化,分析组合框架骨架曲线以及荷载-位移滞回关系曲线特征,研究各参数对组合框架结构骨架曲线和滞回曲线的影响规律。研究结果表明:各参数对骨架曲线和滞回曲线的形状及其特征参数都有不同程度的影响,基于系统的参数分析结果,建议综合考虑各参数影响的组合框架结构骨架曲线和荷载-位移滞回曲线恢复力模型;模型计算结果与试验结果较符合,为组合结构体系的非线性抗震分析提供了理论依据。
Considering the variation of three design parameters such as axial compression ratio,linear rigidity ratio and slenderness ratio,low cyclic repeated horizontal loading test of eight composite frames composed of steel-concrete composite beam and concrete filled steel tube column were conducted.The typical character of skeleton curves and hysteretic curves of load displacements was analyzed.The influence rules of the parameters on skeleton curves and hysteretic curves were studied.The results show that the parameters affect the skeleton curves and hysteretic curves by different levels.Based on the systematic parameter analysis results,the skeleton curve model and load displacement hysteretic model of composite frame are proposed.The calculated results agree well with test results.The research results provide theoretical foundation for nonlinear seismic analysis of steel-concrete composite structure systems.
