用计算机—试验机联机系统进行结构拟动力试验的方法

用计算机-试验机联机系统进行结构拟动力试验的方法是七十年代末出现的新型试验方法,它能较真实地反映地震过程中结构的性能,又能适用于大尺寸模型以至足尺建筑物,因而受到重视。由于这种试验要求较复杂的试验系统和试验控制程序,所以目前国外也只有为数不多的研究单位应用过。本文叙述了拟动力试验的基本原理与试验方法,并介绍了中国建筑科学研究院结构所的联机系统和有关试验控制程序中的动力分析部分。

A Pseudo-Dynamic Method of Structural Experiment by Computer-Actuator On-Line System

The method of pseudo-dynamic test of structure by computer-actuator on-line system is a new experimental method. It can reflect the actual seismic behavior and dynamic response of structures under earthquake motion and can test large scale models as well as full size structures. With this method, complex test system and test control program are necessary. This complex test system has been used for the test of a 12-storyed structural model in the Institute of Building Structures, China Academy of Building Research.
