井干式木结构墙体转角节点力学性能研究
Study on Mechanical Performance of Joints in Log Structural Wall Corners
摘要
Abstract
In this study,laminates with mechanical elastic modulus grades of ME9 and ME10 were selected to make glulam of different strength grades.According to T/CECS 1400-2023"Technical specification for log house building",vertical compression joint specimens,three-point bending joint specimens,bending shear joint specimens,and bending joint specimens of log structure wall corner were designed and produced.The monotonous loading tests were carried out,the failure mode and load bearing performance of the joints were investigated under different mechanical modulus of elasticity and different loading conditions.The results showed that the load carrying capacity of the specimens made with ME9 laminates in the vertical compression,three-point bending,and bending shear condition were reduced by 20%～30%compared to the specimens made with ME10 laminates.In the tests of three-point bending,bending shear,and bending,the damaged specimen joints all showed brittle failure mode.The starting point of the damage cracks of the specimens mostly appeared in the slotted position of the joints.The position and depth of the joint slots had a certain effect on the bearing capacity of the joints.关键词
