摘要
Abstract
The nodes stiffness have a significant effect on the overall stability of the single-layer latticed shell structure.According to the Chinese National Standards (CNS),the nodes of the single-layer latticed shell should be rigid joints.While,due to the characteristic of timber itself,the nodes cannot achieve the rigid connections.This paper demonstrates the feasibility of the semi-rigid connections used in the single-layer latticed shell through analyzing the relationships between the different node stiffness and the safety factor K of the latticed shell overall stability.Furthermore,two glulam semi-rigid joints were tested.The mechanism of fracture and the failure mode were discussed through the experiments.The Moment-Rotation curves of the joints were obtained and therefore the rotational stiffness of the joints was calculated.Finally,the merit and demerit for different glulam semi-rigid joints were analyzed to give an effective use of guidance in the practical project.关键词
