摘　　要：法门寺合十舍利塔,建筑高度147 m,呈双手合十造型,为竖向特别不规则结构。鉴于其结构体系及结构布置的复杂及体型超限,为确保该建筑结构的抗震安全性和适用性,本文利用SAP2000程序对该结构进行了动力特性和弹性时程分析。为了检验结构弹性时程分析的可靠性,将理论分析结果与其振动台试验结果进行了对比,并在此基础上,对该结构进行了抗震性能评价。Dagoba in Famen Temple, an anjali shape structure with 147 m high above the ground, is a typical example of the vertically irregular structures. Because of the complex structural system, the arrangement and out-of-code structural type of this structure, dynamic characteristic analysis and elastic time history analysis were carried out to ensure the seismic safety and serviceability. Moreover, a comparison between numerical analysis and shaking table results was made in order to verify the dependability of the elastic time history analysis. Furthermore, the evaluation of the structural seismic performance was also included in this paper.
