| 摘 要： | 研究木结构古建筑的结构特性对保护和维修古建筑遗产具有重大意义.文中以西安清真寺木牌楼为研究对象,用弹簧单元模拟榫卯连接的半刚接特性,对其进行有限元数值分析.通过对榫卯连接的非线性接触分析得到了其各方向刚度值；在竖向荷载作用下结构的实际内力远小于其强度设计值,其安全裕度在60％以上；给出了结构的运动微分方程,结构模态分析...

| Abstract: | The study on the mechanic performance of ancient Chinese timber structures is of great significance.Taking the pai-lou gateways of Xi'an Great Mosque as a research object,and using the spring elements to simulate the semi-rigid mortise-tenon joints,the authors performed a finite element numerical analysis.The stiffness values of mortise-tenon joints were got by nonlinear contact analysis.Under the vertical load,the internal forces of structure are far less than its design value,and the safety margin of the ... |
