地震工程中的伪动力试验方法

在总结文献的基础上，对伪动力试验的几个问题进行了介绍和讨论，包括伪动力试验在地震工程研究中的作用，伪动力试验的基本原理和方法，伪动力试验的发展过程，伪动力试验的可靠性以及进一步的发展趋势等．文中指出伪动力试验是研究结构和构件在强地震作用下非线性性态和破坏机理的有效手段，它可用于传统结构，也可用于隔震结构和隔震装置．鉴于21世纪世界地震工程发展的新动向和我国目前的情况，作者认为我国在发展地震工程实验设备和技术的计划中，应把伪动力试验硬件和软件的研究与开发放在重要地位，建议有关研究机构给予更多的关注．

Pseudo-dynamic test method for earthquake engineering

Based on literature review, several issues of Pseudo-Dynamic Test (PDT) are introduced and discussed in this paper briefly, including the role of PDT in research of earthquake engineering, its basic principle and process,the development history, the reliability and further advance of PDT, etc. It is shown that PDT is an effective method for research of non-liner behavior and rupture mechanism of structures and elements under strong earthquakes. PDT not only can be used for traditional structures but also for isolated structures and isolation devices. In view of the trend of earthquake engineering in the 21 century and the present situation both at home and abroad, the authors suggest that research and development of the hardware and software of PDT should be put into an important status in facility and technique development plan, so that more and deep concern may be awarded by the relative institutes and researchers.
