附属结构地震反应的隔震方法

An Isolation Method for the Earthquake Responses of Secondary Structures

本文提出了附属结构地震反应的隔震设计思想,这是一种具有明显实用价值的减震方法.文中分析了影响附属结构隔震效果的主要因素,研究了其隔震机理.理论和应用分析结果表明:采用隔震方法,不但可以有效地降低顶部附属结构的鞭梢效应,而且对于下部主体结构也有一定程度的减震作用.

The isolation design strategy about the earthquake responses of secondary structures is brought forward in this paper, which is a kind of useful shock—absorbing method. The main factors which affect the isolation effectiveness of the secondary structures are analysed, and its isolation principles are studied. The theory and application results show that the isolation method can remarkablly reduce the whipping effects of top secondary structures, therefore produce shock—absorbing effects on the lower main structures.
