石柱木梁架古建筑抗震性能临界状态理论分析

Critical state theoretical analysis of seismic performance of ancient buildings with stone columns and wooden beams

石柱承托木梁架结构体系作为山西古建筑典型的结构体系之一,其在地震作用下易形成摇摆构架,摇摆构架不同运动状态直接关系到古建筑结构安全状态的判定。基于摇摆构架理论分析模型的基础,以高平嘉祥寺毗卢殿作为研究对象,重点探讨了在地震荷载作用下摇摆构架四种运动临界状态(相对静止、相对滑移、摇摆和滑移摇摆)的控制条件,为后续研究类似石柱承托木梁架古建筑结构体系非线性动力分析提供理论依据。

As one of the typical structural systems of ancient buildings in Shanxi,ancient building with stone columns and wooden beam frames are prone to form a rocking structure under the action of earthquakes.The different motion states of the rocking structure are directly related to the safety state of the ancient building.Based on the theoretical analysis model of the rocking frame,this paper takes the Pilu Hall of Gaoping Jiaxiang Temple as the research object,discusses the control conditions of the four motion states of the rocking frame,namely relative stationary,relative slip,swing and slip swing,are given under seismic loads.The conclusion provides a theoretical basis for the subsequent study of nonlinear dynamic analysis of ancient building with stone columns and wooden beam frames.
