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,并介绍了建研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。 The method of using the computer-tester on-line system to carry out the structure pseudo dynamic test is a new test method that emerged in the late 1970s. It can truly reflect the performance of the structure in the earthquake process, and can also be applied to large-scale models and even full-scale construction. Things are therefore valued. Because this kind of test requires more complicated test system and test control procedure, so now only a few research units abroad have applied. This article describes the basic principles and test methods of the pseudo-dynamic test, and introduces the on-line system of the Institute of Industrial Science and Technology and the dynamic analysis part of the relevant test control program.
