少数民族地区木结构性能分析——弹簧代替木结构榫卯节点

Analysis on the Performance of Wood Structure in Minority Areas——Replacing Mortise and Tenon Joints of Wood Structure with Spring

分析少数民族建筑在地震作用下的安全性能,需要在有限元分析软件ADINA中,建立少数民族建筑木结构主要框架结构模型,但由于木结构的节点连接处多为榫卯节点,接触面众多,且各接触面的摩擦因数很难精确确定,本文采用弹簧单元来代替少数民族建筑木结构中的榫卯节点,从而简化力学模型,以进行接下来的研究。

In order to analyze the safety performance of the minority buildings under earthquake, it is necessary to establish the main frame structure model of the minority buildings in the finite element analysis software Adina. However, because the joints of wood structure are mostly mortise-tenon joints, there are many contact surfaces, and it is difficult to determine the friction coefficient of each contact surface accurately, the virtual spring element is used to replace mortise-tenon joints in wood structure, thus simplifying the mechanical model for the rest of the study.
