【摘要】 介绍了在结构动力反应模拟试验系统的研制过程中遇到的结构技术难题以及相应的解决办法。其中包括结构自反力体系的概念设计、结构设计与计算、台体稳定分析、动力反应分析等。这一大型抗震试验系统由美国加州通局ＣＡＬＴＲＡＮＳ）、圣迭戈加利福尼亚大学（ＵＣＳＤ）和ＭＴＳ公司联合研制，将用于土木工程中阻尼器、隔震支座装置的足尺和实时动力试验。更多还原

【Abstract】 Some technical difficulties involved in the "SRMD Testing System", developed by CALTRANS, UCSD and MTS Company , and the methods to handle them are introduced in this paper. The conception design of the self-reacting frame, supporting structure design , stability of platen and dynamic analysis for the structure are the important contents for the establishment of the system and its future usage. This testing system will be used in real-time dynamic or seismic tests of full-scale dampers, isolation bearings, and displacement limiting devices in bridges or buildings. It can also be used as a shaking table. The whole developing process and experience will be a treasure to any other similar projects in the future.更多还原
