考虑损伤效应的型钢高强高性能混凝土框架柱恢复力模型研究
|
摘要
为研究型钢高强高性能混凝土框架柱的抗震特性,基于已进行的9榀型钢高强高性能混凝土框架柱低周反复加载试验结果,进一步分析了其滞回特性,并将其骨架曲线简化为带下降段的理想三折线型骨架曲线模型,给出了骨架曲线的确定方法,同时简化了滞回环。通过引入基于损伤的循环退化指数对构件在反复荷载作用下的屈服荷载、硬化刚度、卸载刚度、再加载刚度以及承载力等各项力学性能指标的退化规律进行了描述,建立了基于损伤的型钢高强高性能混凝土框架柱的恢复力模型,给出了具体的滞回规则。结合试验结果,对恢复力模型的有效性进行了验证。研究结果表明:该模型能够较好地描述型钢高强高性能混凝土框架柱在反复荷载作用下的滞回特性,研究结果可为该类结构的弹塑性时程分析提供理论参考。
To research the seismic behavior of steel reinforced high strength high performance concrete(SRHSHPC) frame columns,the hysteretic behavior of 9 SRHSHPC frame column specimens under low cycle reversed loading were investigated by test.Based on the test results,the ideal trilinear skeleton curve model of frame columns considering descent segment was established.The determination method of the skeleton curve model was given and the hysteretic loops simplified.The cycle degradation indices based on damage was proposed,which was used to describe the degradation law of specimen mechanical properties such as yielding load,hardening stiffness,unloading stiffness,reloading stiffness and bearing capacity.And then,the restoring force model of SRHSHPC frame columns based on damage was established.The specific hysteretic rule was given.Finally,the validity of damage model was verified by comparison with the test results.The result shows that the proposed restoring force model can well reflect the hysteretic characteristics of SRHSHPC frame columns under reversed loading.The study results will provide theoretical reference for the elasto-plastic dynamic analysis of SRHSHPC structures.
