针对叠层橡胶支座基础隔震体系的性能、分析与设计等,介绍了由笔者所在课题组完成的寒冷环境下叠层橡胶隔震支座力学性能试验研究的成果、实振型分解法分析非比例阻尼隔震结构动力响应、隔震结构动力分析软件、橡胶隔震器与地下室悬臂柱串联后所组成的结构系统动力稳定性、高烈度区使用智能隔震体系的控制算法及甘肃省隔震构造图集等研究成果。同时介绍了本课题组负责设计的甘肃省叠层橡胶支座隔震体系的若干工程简况。

The result of a series of studies on base isolated structures carried out by the writer＇s research group from the view-point of performance, analysis and design of LRB isolated structures is presented. The studies include a cyclic test of rubber isolator in cold environment, real mode superposition method for dynamic analysis of non-proportionally damped isolated structures, a computer software for analysis and design of isolated structures, dynamic stability analysis of basement column serially connected with rubber isolator, control algorithms for smart isolation in regions with high earthquake intensity, and the standard drawing for the detailing design of base isolated buildings. A brief introduction is also made to some isolated buildings, designed by the writerg research group, with application of LRB isolators.
