引言本文试图对实验技术作一简要回顾。利用此实验技术可以获得结构动力特性以及循环加载下整个结构、部件及结构构件的荷载—变形性状方面的资料。文章着重叙述实验技术的物理方面,包括激振装置和控制以及实验数据的采集与处理。本文分为三个部分:第一部分叙述结构现场试验研究,第二部分为实验室试验研究,第三部分是关于用微型计算机作为试验控制和数据处理的实验系统的简短讨论。 Introduction This article attempts to make a brief review of experimental techniques. Using this experimental technique, structural dynamic characteristics and load-deformation properties of the entire structure, components, and structural members under cyclic loading can be obtained. The article focuses on the physical aspects of experimental techniques, including the excitation device and control and the acquisition and processing of experimental data. This article is divided into three parts: the first part describes the field test study of the structure, the second part is the laboratory test study, and the third part is a brief discussion about the use of microcomputer as experimental system for experimental control and data processing.
