A substructured on - line computer - actuator hybrid method for inelastic earthquake response of structures is presented. A complete structural system is divided into analytical substructures and experimental substructures. Restoring forces for the experimental substructures modeling only the critical regions are directly measured from a specimen loaded based on its current deformation state. The remaining portions are taken as analytical substructures in which presently available analytical models are used to describe their restoring-force characteristics. Using this substructured hybrid loading system, critical members with proper boundary conditions can be tested under realistic earthquake loads. Thus, inelastic earthquake response of the total structure can be accurately and reliably predicted. To extend the applicability of substructured hybrid method, a three degree-of -freedom loading system capable of testing seismic isolators and columns under combined axial, shear, and bending loads has been developed and implemented. Finally, high-damping rubber seismic isolators and steel box-section and RC colurrms were tested using this loading system.

提出了一种结构非弹性地震反应的子结构在线计算机-执行器混合方法.一个完整的结构系统分为分析子结构和实验子结构。恢复力的实验子结构建模的关键区域直接测量从加载的基础上，其当前的变形状态的试样。其余部分被视为分析子结构，其中目前可用的分析模型被用来描述其夹紧力特性。使用这种子结构混合加载系统，关键成员与适当的边界条件下，可以在现实的地震荷载下进行测试。因此，可以准确可靠地预测整个结构的非弹性地震反应。为了扩展子结构混合方法的适用性，已经开发并实施了能够在组合轴向、剪切和弯曲载荷下测试隔震器和柱的三自由度加载系统。最后，利用该加载系统进行了高阻尼橡胶隔震支座、钢箱形截面和钢筋混凝土柱的试验研究。
