Refined Finite Element Simulation Analysis of Different Types of Mortise and Tenon Joints
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.
