Abstract

Mortise connection is a unique way of connection in the wood structure of ancient buildings in China. This paper takes the mortise and mortise joints of wood window frame as the object. Eight models of wooden window frames are built in ANSYS software with the parameters of tenon diameter and tenon length. The static performance of them is studied. Through simulation loading, the ultimate bearing capacity of the model under vertical and horizontal loads is obtained, and it is concluded that the Mohr strength of the dangerous point and the maximum displacement value at the contact of the mullion and mullion are linearly related to the applied load. Through the parameter analysis, such as the diameter and length of mortise and tenon joint, the optimal design of this kind of mortise and tenon joint component are carried out so as to provide the theoretical basis for its application in the actual project.

Highlights

Mortise and tenon structure is a kind of component which combines the concave and convex parts to connect the two components[1]
The protruding part is tenon, the concave part is mortise. This unique connection mode endows the wood structure with good elasticity, and each node is rigid and flexible, which makes the wood structure have good energy consumption capacity. This kind of connection structure is widely used in ancient wood structure buildings in China, and it is still used in the design and manufacture of modern wood furniture and prefabricated wooden villa[2]
In the vertical load, compared with five models with tenon length of 60mm, it is found that the ultimate bearing capacity is larger when the diameter is 10 mm

Summary

1.Introduction

Mortise and tenon structure is a kind of component which combines the concave and convex parts to connect the two components[1]. The protruding part is tenon, the concave part is mortise This unique connection mode endows the wood structure with good elasticity, and each node is rigid and flexible, which makes the wood structure have good energy consumption capacity. This kind of connection structure is widely used in ancient wood structure buildings in China, and it is still used in the design and manufacture of modern wood furniture and prefabricated wooden villa[2]. There are more than 100 kinds of mortise and mortise structures, which can be roughly divided into face to face structure, point structure, and joint mortise and mortise structures. It is studied that the static performance analysis of face to face mortise and tenon structure under vertical and horizontal loads
