引言众所周知,保护大楼免受地震是通过在结构和地面之间引入挠性而起到基础隔离的。在过去10年中已发展了一系列基础隔离体系,大部分采用层迭橡胶为主要部件。但是,极大多数体系在联接支座之间需要附加装置以满足一个实用隔离体系的不同需要,例如风力影响控制高阻尼性及耐燃性。在本文中介绍一种基础隔离体系,在这个体系中,上述要求均应作为橡胶支座的固有特性来达到,这样可以简化设计并降低成
Introduction It is well-known that protecting buildings from earthquakes is based on isolation by introducing flexibility between the structure and the ground. In the past 10 years, a series of basic insulation systems have been developed, mostly using laminated rubber as the main component. However, most systems require additional devices between the coupling supports to meet the different needs of a practical isolation system, such as the wind impact control for high damping and flame resistance. In this paper, a basic insulation system is introduced. In this system, the above requirements should be achieved as the inherent characteristics of rubber bearings, which can simplify the design and reduce the
