摘　　要：通过有限元软件ABAQUS对广府木结构祠堂的典型节点箍头榫和直榫进行参数分析,充分考虑节点承载力和刚度的影响因素和木材正交各项异性的材性特点,两类节点各选取一定数量建立三维实体有限元模型,分析并获得各种参数变化下节点弯矩承载力和节点转动刚度的变化规律。本文还对节点的M-q曲线进行了双线性拟合,给出了考虑节点各尺寸参数的拟合公式,研究结果将为广府木祠堂修缮和结构加固提供节点承载力和节点转动刚度计算依据和取值参考。The FEA software ABAQUS is used to perform the parametric analysis on two typical types of joints of the timber ancestral hall in Canton region,the hood-head tenon and straight-tenon joints. The variables included the influencing factors of bearing capacity and stiffness,and the orthogonal anisotropy of timber. A certain number of these two types of joint models were chosen to build 3D FEM analysis model with solid element. The influence law of each variable on the bending capacity and rotational stiffness was obtained. The bilinear M-q curves fitting and formulas were also preceded,considering parameters of the given joint sizes. The research work is for reference of the bearing capacity and rational stiffness parameter selection and calculation during the repairing and strengthening of timber ancestral hall in Canton region.
