Study on Numerical Model for Metal Joint of Glulam Members

目的为了明确木结构的力学行为，有必要对木结构的嵌入行为进行研究。木结构的嵌入是木结构中最重要、最基本的因素之一。本文对木梁与木柱之间的承载进行了研究，并进行了平行于木纹的埋设试验。方法采用道格拉斯冷杉木材进行木梁与木柱之间的承载试验。实验分为均匀分布嵌入和三角分布嵌入两种类型。在这些试验中，梁的深度和宽度、到端部的距离、到边缘的距离和柱的深度是准确模拟这种性能的重要参数。集成材承载试验的力学模型使我们能够表示每个参数的影响。

PurposeIt is necessary to study the behavior of embedment in order to specify mechanical behavior of timber structures. The embedment of timber is one of the most important and basic factors of timber structures. In this paper, bearing between timber beam and timber column is investigated carrying out embedment tests parallel to grain.MethodBearing tests between timber beam and timber column were carried out using glulam timbers, made of Douglas Fir. The tests were classified as two types, using uniformly distributed embedment and triangular distributed embedment. In these tests, depth and width of beam, distance from end, distance from edges and depths of column are important parameters to accurately model the behaviors.ResultEffects of parameters for glulam timbers are revealed after bearing tests. Mechanical models for bearing test of glulam timbers enable us to represent the effects of each parameter.
