| 摘 要： | 为探讨土-结构相互作用对西安钟楼地震反应的影响,建立了钟楼上部木结构-台基-地基三维有限元模型,基于粘-弹性人工边界条件,利用振型分解反应谱法进行了地震反应分析。结果表明,考虑相互作用木结构2层相对位移反应增大了2.12倍,台基相对于地面间的相对位移增大了44%。因此,在对钟楼结构进行地震反应分析时必须考虑土-结构相互作用。

| Abstract: | In order to study the influence of soil-structure interaction on seismic responses of the Xi'an bell tower,3-D finite element model of the Xi'an Bell Tower is established in this paper,which includes timber structure,tower base and foundation.Based on viscous-spring artifical boundaries,seismic response analysis of the Bell Tower are conducted using mode decomposition response spectrum method.The results indicate that relative displacement of the second floor of timber structure is increased by 2.12 times and displacement of tower base relative to ground is increaced by 44% when soil-structure interaction is considered.Therefore,soil-structure interaction should be considered in the seismic response analysis of the Bell Tower. |
