摘要
榫卯节点是传统木结构建筑中的关键部位,其力学性能对结构整体性能有着重要的影响.文章采用有限元软件ABAQUS对传统木结构中典型的透榫和半榫节点开展精细化有限元模拟,得出不同类型榫卯节点的滞回性能,并对比分析了不同类型榫卯节点的力学性能.结果表明,透榫和半榫节点的滞回曲线均具有滑移特征,透榫的变形和耗能能力优于半榫,承载能力大于半榫,屈服弯矩和极限弯矩分别为半榫的6.12倍和7.69倍,弹性转动刚度是半榫的6.13倍.
Abstract
In the traditional timber structure,the mechanical behavior of mortise-tenon joint is a critical part and has a significant influence on the behavior of the whole structure.In this paper,the finite element software ABAQUS is used to carry out a fine finite element simulation of typical mortise and tenon joints in the project.The hysteretic performance of different types of mortise-tenon joints is obtained,and the mechanical properties of different types of mortise-tenon joints are compared and analyzed.The results show that the hysteresis curves of the through-tenon and half-tenon joints have slip characteristics.The deformation and energy dissipation capacity of the through-tenon are better than that of the half-tenon,and the bearing capacity is greater than that of the half-tenon.The yield moment and ultimate moment are 6.12 times and 7.69 times that of the half-tenon,respectively,and the elastic rotational stiffness is 6.13 times that of the half-tenon.
