摘要
通过对中国古代木结构的结构特性分析，得出了合理的力学模型，采用变刚度单元模拟真实木结构梁柱的榫卯连接，用虚拟单元的不同刚度条件反映真实的半刚性连接，将变刚度单元加入有限元程序，对西安东门城楼进行了弹塑性有限元分析，得出了不同刚度系数下的力学性能。
The elasto plastic analysis with the superstructure located the East Gate of Xi’an city has been performed by FEM in this paper.The mechanical model and properties for the joints and all structure have been obtained.by applying the elements with variable rigid joints with mortise and tenon of beam column system to the real wooden structure,and different rigid conditions of the virture element with semi rigidity.The elements with variable rigid is included in the general matrix of rigidity.The results are of great value for the explorative studies of ancient Chinese wooden structure.
