建筑物基础隔震体系设计

Design of base isolation system of building

简要介绍了几种隔震元件及限位消能元件的基本性能，探讨了影响其性能的主要因素。通过试验研究及计算机分析，就隔震体系的匹配关系及设计提出了简化计算方法。分析表明，只要合理地选用隔震元件及限位消能元件，体系的基底剪力完全可以由设计者控制在某一个水准。

In this paper, the basic behavior of some sliding devices and displacement restriction and energy absorption device are introduced briefly, the main factors that affect their behavior are studied. Through these and computer analysis, a simple method of computing the match relation and design of base isolation system are given. Analysis shows that as long as the sliding devices and displacement restriction and energy absorption devices are selected properly, the base shear of the system may be controlled not to exceed a certain level by the designer.
