摘要

本文的目的是在假设木梁胶结接缝是可变形的情况下，建立木梁胶结接缝的近似数值模型。这个近似模型是建立在平面线性弹性理论通解的观测基础上的。假定木材是正交异性的。该节点可承受包括轴力、剪力和弯矩在内的复杂载荷组合。在这个框架内，胶粘剂应力的分析关系，以及胶粘剂的应力和位移，以一种对工程实践有用的形式推导出来。数值算例表明，与基于平面线性弹性理论的一般模型相比，该近似模型具有较高的精度。

APPROXIMATE NUMERICAL MODEL FOR ADHESIVE SCARF JOINTS IN WOODEN BEAMS

The purpose of this paper is to formulate an approximate numerical model for adhesive scarf joints in wooden beams under the assumption that the joint is deformable. This approximate model is founded on observations resulting from the general solution of the plane linear theory of elasticity. It is assumed that wood is orthotropic. The joint can be subjected to a complex load combination including an axial force, a shear force and a bending moment. Within this framework, analytical relations for stresses in the adhesive, as well as stresses and displacements of the adherends, were derived in a form useful for engineering practice. A numerical example proves the high accuracy of the approximate model when compared to the general model based on the plane linear theory of elasticity.
