古建筑高台基对地震反应的影响
|
摘要
高台基是许多古建筑重要的组成部分,为了探讨高台基对结构地震反应的影响,本文以西安钟楼为研究对象,建立了台基与上部木结构共同作用的三维有限元模型,采用振型分解反应谱法进行了地震反应分析,得到了对结构进行地震反应分析时应取的振型数目,与不考虑高台基时的动力特性和地震反应做了对比,并对不同侧移刚度高台基的影响进行了分析.结果表明,古建筑高台基使其上部结构的地震反应放大,地震反应分析必须考虑高台基的影响.
High-station base is an important part of many ancient buildings.In order to study the influence of high-station base on the structure seismic responds,3-D finite element model of Xi'an Bell Tower which includes high-station base and timber structure is established in this paper,and mode decomposition response spectrum method is used.The comparison between the dynamic performance and the seismic response has been conducted where high-station base is neglected.And the influences of different lateral rigidity of high-station base also have been studied.The results indicate that seismic responses of timber structure are enlarged when high-station base is considered.
