| 摘 要： | 随着钢结构跃层加层技术的应用,其抗震和隔震技术越来越受到重视。本文结合具体的工程实例,根据现行的抗震规范,通过建立空间三维有限元模型分析了采用隔震技术的跃层加层框架的动力特性,并用时程分析法对隔震结构及其相应的非隔震结构进行了地震反应分析,比较了两种结构的抗震性能,计算结果可为该类结构的隔震设计提供参考。

| Abstract: | According to the code for seismic design of building and combining with the study cases, The dynamic characteristics of adding extra-floors spanning existing building with the base-isolation technology are analyzed by establishing three-dimensional models, and the seismic responses of the structure with base-isolation technology compared with normal structure are obtained by using time history analysis method. The results of compared and studied can be served as the basic of such structure design. |
