摘　　要：对具有传统文化的仿古建筑进行加固时,将隔震技术用于仿古建筑的抗震加固,可不改变建筑外立面和装修的建筑风貌。以高烈度区某大殿式仿古建筑防震减灾为研究对象,建立有限元模型进行非线性时程分析,探究了隔震层屈重比和水平等效刚度对大殿式仿古建筑隔震体系动力响应的影响规律,给出了此类建筑隔震层屈重比和水平等效刚度的合理取值范围:屈重比为0.015~0.035,水平等效刚度为实际隔震层刚度的0.7~1.2倍,可为既有大殿式仿古建筑隔震加固设计提供参考。When the antique building with traditional culture is reinforced, the seismic isolation technology is used for the seismic reinforcement of the antique building.The architectural style of the building facade and decoration can not be changed.Taking a hall-style antique building of earthquake disasters in high intensity area as the research object, it establishes finite element model for nonlinear time history analysis, and explores the influence law of the yield ratios and horizontal equivalent stiffness of the isolation layer on the dynamic response of the seismic isolation system of the hall-style antique building.The reasonable value range of the yield ratios and horizontal equivalent stiffness of the isolation layer of this kind of building is given.The flexor weight ratio is 0.015~0.035,and the horizontal equivalent stiffness is 0.7~1.2 times of the actual stiffness of the isolation layer.It can provide reference for the seismic isolation and reinforcement design of existing hall-style antique buildings.
