某重檐歇山式仿古建筑反应谱分析

A Response Spectrum Analysis of the Multiple Eave Hipped Roof

本文以某重檐歇山式仿古建筑大雄宝殿为例,通过理论分析与数值模拟,对其独特的结构形式特点进行了研究,着重分析了其反应谱.通过软件建立此结构的有限元模型与相应的对比模型,进行了有限元分析,并对结果进行了对比研究,得出仿古建筑的结构反应谱分析,以及柱脚结构的变形、结构主应力、结构剪应力的分析.同时,根据结构特点提出了相应的加固措施.通过对仿古建筑结构谱分析的研究,可为现存古建筑保护、维修、加固提供相应的理论依据与技术参考.

The study is based on the research of the multiple eave hipped roof style Mahavira Hall.By using theoretical analysis and numerical modeling,the study focuses on the unique characteristics of the building＇s structure and its response spectrum.The study also makes an finite analysis by building the finite model and its relating contrast model with certain software.Thereafter a comparative study is made of the results,which provides the response analysis of ancient building structure,analysis of transformation of column structure,the analysis of principal stress and the shearing stress of the building structure.Furthermore,the study puts forward the correlating reinforcing measures in accordance with the feature of the structure.In conclusion,the study of the structural spectrum analysis of the ancient building provides a theoretical basis and technical reference for the protection,maintenance and reinforcement of ancient buildings.
