摘要
为了研究SRC-RC转换柱的抗震性能,进行了5根转换柱模型的拟静力试验,得到了SRC-RC转换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SRC-RC转换柱恢复力模型采用双线性模型和退化三线型模型,并建立了恢复力模型,给出了恢复力模型各阶段刚度参数的计算公式,为SRC-RC转换柱的非线性地震反应分析提供了理论参考。
In order to investigate the seismic resistant performance of SRC-RC transfer column,the quasi-static tests are conducted on 5 transfer columns under low-cyclic and reversed loading,and the hysteretic loops and skeleton curves of load displacement are obtained.Based on the test results and analysis,the main characteristic points and the law of stiffness degradation are presented,the two-linear restoring model and three-linear restoring model are proposed and established,and the calculation formulas of stiffness parameter in restoring force model at different stages of deformation are also presented.The proposed models can be applied to the non-linear seismic analyses and the design of SRC-RC transfer column.
