摘　　要：以宁波保国寺大殿为例 ,应用有限元理论对榫卯结构和大殿整体进行分析 ,得到典型榫卯连接刚度以及大殿的固有频率、振型以及Elcentro地震波作用下的位移响应曲线 .文中提供的方法和结论 ,可供古建筑保护工作者在进行类似结构分析中借鉴 .A dynamic analysis on ancient wooden structure of Baoguo Temple located in Ningbo was performed with FEM. Mortise and tenon connection is supposed to be semi-rigid connection. Its stiffness value can be calculated by applying the finite element contact theory. Then the inherent property of Baoguo Temple structure and the displacement response under the action of seismic load are obtained by using finite element method. Based on the results, the scientific foundation for structure of the Hall of Baoguo Temple’s safety and reliability can be provided. The analysis mentioned above could also be applied on other ancient wooden structures.
