四川通济镇幼儿园基础隔震设计与分析

基础隔震是工程结构抗震的新技术,它是在上部结构与基础之间设置隔震层,籍以阻隔地震能量的传递,减少结构的地震反应,减轻地震破坏。本文介绍了位于抗震设防烈度为8度区的四川通济镇幼儿园基础隔震结构的设计与分析方法,分析计算表明:基础隔震可延长结构自振周期,减小上部结构的地震作用力,减少结构的变形。

Design and Analysis on Base-Isolation structure of Kindergarten in Sichuan Tongji Town

Base-isolation technology is a new anti-seismic technology,which is set up the isolation layer between the upper and foundation of the buildings in order to block transmission of seismic energy and reduce the seismic response of engineering structures and reduce earthquake damage.This paper describes the base-isolation design of kindergarten in Sichuan Tongji Town in an 8-degree earthquake intensity zones.Time-history analysis method shows: base-isolated may extend natural vibration period,and reduce the se...
