| 摘 要： | 将拟动力实验方法和子结构技术应用于多维多点地震输入下的结构响应研究，解决了结构在多维多点地震输入下的实验问题，为结构在多维多点地震输入下的研究提供了新的方法，也拓广了拟动力实验方法的应用范围。针对框架结构在两点地震波输入的情形，文中给出了相应的拟动力实验数值积分方法，并对所提出的方法进行了实验验证。

| Abstract: | The pseudodynamic test method with substructure technique is used in the structural response research under multidimensional and multipoint earthquake input. The central difference testing integration algorithm and unconditionally stable implicit testing integration algorithm were given according to the frame structure. A verification test was carried out for two points earthquake input. The test results show that the proposed methed is available for the structural nonlinear response wb when the structure is subjected to multidimensional and multipoint earthquake excitation. |
