摘要:
建立了透榫节点的ABAQUS有限元分析模型，并将模拟分析结果与透榫节点在低周反复荷载作用下的试验结果进行了比较.在此基础上，研究了榫头高度、滑动摩擦系数、横纹弹性模量、顺纹弹性模量、顺纹抗拉强度以及轴压比等参数对古建筑木结构透榫节点受力性能的影响.分析结果表明：随着节点榫头的高度和摩擦系数的增大，透榫节点的刚度不断增大；木材的顺纹和横纹弹性模量仅对节点在弹性阶段的刚度有一定影响；顺纹抗拉强度对节点刚度几乎无影响；随着榫头高度、摩擦系数、弹性模量以及顺纹抗拉强度的增大，透榫节点的抵抗弯矩值均有不同程度的提高；一定范围内，轴压比对受力性能几乎无影响.
Abstract:
An ABAQUS finite element analysis model of throughtenon joint was proposed, and the results of the analysis were compared with the experimental results under low cyclic loading. The influences of several parameters such as the height of the tenon, coefficient of friction, compressive modulus of elasticity, tensile modulus of elasticity, tensile strength, and axial compression ratio on mechanical behavior of through-tenon joints in ancient timber buildings were studied. The results show that the stiffness reduce gradually when the height of the mortise and the coefficient of friction increases, and the modulus of elasticity only has a certain degree of influence on the stiffness of the elastic stage, the tensile strength has almost no effect on the stiffness. The moment of resistance has been improved in different degrees when the height of the mortise, the coefficient of friction, the modulus of elasticity, the tensile strength increases. Within a certain range, the axial compression ratio has almost no effect on mechanical behavior.
