摘　　要：将有限元软件OpenSees Navigator应用于子结构混合仿真试验,介绍了基于OpenSees Navigator的子结构混合仿真试验方法的试验原理、试验系统组成和误差控制方法,并通过八层实腹式SRC异形柱框架子结构混合仿真试验结果和有限元软件OpenSees Navigator的数值模拟结果来验证该试验系统及方法的有效性和准确性。研究结果表明,试验预加载得到的命令位移和反馈位移时程曲线吻合程度较好,验证了该试验系统的有效性;模型结构的加速度反应、位移反应和层间剪力试验结果和模拟结果较为接近,表明该子结构混合仿真试验系统和试验方法能够较好地反映SRC异形柱框架结构在地震作用下的动力反应,将该试验系统应用于工程结构的抗震性能研究能够取得良好的效果。The finite element software OpenSees Navigator was applied to the substructure hybrid simulation test.The test principle,test system composition and error control method of the substructure hybrid simulation test method based on OpenSees Navigator were introduced.Through the substructure hybrid simulation test results and the numerical simulation results of the finite element software OpenSees Navigator of the eight-layer solid-web SRC special-shaped column frame,the effectiveness and accuracy of the test system were verified.The research results show that the command displacement and feedback displacement time-history curves obtained by the test preloading are in good agreement,which verifies the effectiveness of the test system;test and simulation results of the acceleration response,displacement response,and interlayer shear of the model structure are more closer,which indicates that the substructure hybrid simulation test system and test method of the substructure can better reflect the dynamic response of the SRC special-shaped column frame structure under earthquake action,and the test system can be used to study the seismic performance of engineering structures to obtain good results.
