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。
The quasi-dynamic experimental method and substructure technology are applied to the structural response study under multi-dimensional and multi-point seismic input, and the experimental problems of the structure under multi-dimensional and multi-point seismic input are solved, which provides a new structure for research under multi-dimensional and multi-point seismic input. The method also broadens the scope of application of the pseudo-dynamic test method. For the two-point seismic wave input of the frame structure, the corresponding numerical method of numerical simulation of the pseudo-dynamic experiment is given in the paper, and the proposed method is verified experimentally.
