开发了一种新的结合子结构技术的在线混合测试系统。在该系统中，通用有限元软件被用来精确地获得数值子结构的恢复力。重复使用重启选项以适应具有在线测试的交替加载和分析特性的软件，但不接触源代码。对一个8层隔震结构进行了试验，以评估所提出的试验系统的可行性和有效性。整个结构分为两个子结构，即上部结构和基础隔震层，上部结构将通过软件进行分析，基础隔震层将进行物理测试。试验中考虑了基础隔震层与周围墙体之间的碰撞。整个结构响应合理，运行平稳，无故障。版权所有© 2006约翰威利父子有限公司.
A new on‐line hybrid test system incorporated with the substructuring technique is developed. In this system, a general‐purpose finite element software is employed to obtain the restoring forces of the numerical substructure accurately. The restart option is repeatedly used to accommodate the software with alternating loading and analysis characteristic of the on‐line test but without touching the source code. An eight‐storey base‐isolated structure is tested to evaluate the feasibility and effectiveness of the proposed test system. The overall structure is divided into two substructures, i.e. a superstructure to be analysed by the software and a base‐isolation layer to be tested physically. Collisions between the base‐isolation layer and the surrounding walls are considered in the test. The responses of the overall structure are reasonable, and smooth operation is achieved without any malfunction. Copyright © 2006 John Wiley & Sons, Ltd.
