摘要

为了研究型钢混凝土异形柱的抗震性能,进行了17根型钢混凝土异形柱模型的拟静力试验,得到了型钢混凝土异形柱模型在低周反复荷载作用下的滞回曲线和P-Δ骨架曲线。通过试验结果的分析,给出了各关键点的试验数据及刚度退化规律,建议型钢混凝土异形柱恢复力模型采用双线型模型和退化三线型模型,并给出了恢复力模型各阶段刚度参数的计算公式,为型钢混凝土异形柱的非线性地震反应分析提供了理论参考。
In order to investigate the seismic performance of SRC special-shaped columns,the tests were conducted on 17 SRC special-shaped columns under low cyclic reversed loading,and the loading-displacement hysteretic loops and the skeleton curves were obtained.Based on the test results,the main characteristic points and the law of stiffness degradation were presented;the bilinear restoring model and trilinear restoring model were built and provided,and the calculation formulas of stiffness parameter in restoring force model at different stages of deformation were also presented.The provided models can be applied to the non-linear seismic analyses and design of SRC special-shaped columns.
