| 摘 要： | 对并联组合基础隔震体系的周期和阻尼比进行了分析,并对其影响因素进行了讨论,同时提出了计算该种结构体系的简化计算方法.通过对某工程实例所采用的滑板支座及橡胶隔震支座进行了静力试验,获得其隔震性能参数,并应用SAP2000进行了该工程多遇与罕遇地震下的弹性时程分析计算,结果表明罕遇地震下上部结构仍处于弹性工作状态,且简化方法的计算结果与该结果比较接近,能够满足工程设计的要求.

| Abstract: | The period and damping ratio of parallel-composite base isolation system are analyzed,and the influence factors are also discussed.A simplified method for calculating this parallel- composite base isolation system is also offered.Taking an building moving project with this system designed by the author as an example, static tests have been respectively made on slider bearings and rubber bearings,and performance parameters were obtained.The example shows that the results which are calculated by the simplifie... |
