摘　　要：开元寺-天王殿是我国传统建筑中典型的单檐歇山唐式建筑,通过屋架体系设托梁-立柱的传统结构模型1与横向折梁受力的结构模型2,分析两个模型的周期比、最大层间位移角、配筋值等指标,结果表明按照模型2来设计能满足现行规范要求,给今后类似设计提供了新的可能性;考虑到屋面弦梁、枋梁空间交错,处于不同标高,使用YJK软件对结构进行了弹性时程分析与动力弹塑性时程分析,结果表明结构满足抗震设计规范的要求,能够达到“三水准”抗震设防性能的能力,不需要采用地震力放大系数;通过在动力弹塑性下的损伤分析,提出结构易损伤的部位。对天王殿结构在实际中存在的抗震不利部位,如场地抗震不利、室内外大高差、屋面交错节点、收分柱等,提出了有效的加强措施。Tianwang Hall in Kaiyuan Temple is a typical one eaved building in traditional Chinese architecture.By comparing the traditional structural model 1 of joist-column with the structural model 2 of transverse bending beams,analysis the period ratio,the maximum inter story displacement angle and the reinforcement value of the two models shows that the design according to the model 2 can meet the requirements of the current code,which provides a new possibility for similar design in the future;considering that the roof beams are staggered in space and at different elevations,the elastic time history analysis and dynamic elastoplastic time history analysis of the structure are carried out by using the finite element software of YJK,the results show that the structure can meet the requirements of the seismic design code,and can achieve the"three levels"of seismic performance without the use of seismic force amplification factor;based on the damage analysis under dynamic elastoplasticity,the vulnerable parts of the structure are proposed.The effective strengthening measures are put forward for the disadvantageous seismic parts of the Tianwang Hall structure,such as site seismic disadvantage,large height difference between indoor and outdoor,roof staggered node,scoring column.
