摘要

在过去的二十年里，木材在建筑中的应用越来越受到研究人员和可持续建筑设计师的关注。因此，人们开始研究气候对木材结构的影响，其中许多研究侧重于含水率引起的木材变化。本研究对三个测试组进行了四点弯曲测试，每个测试组包含 30 个样本。第一组在自然条件下进行测试，第二组和第三组则完全浸水。第三组用保护材料上釉。结果表明，含水量增加会导致弹性模量和断裂模量发生变化。同时，一些样品的材料行为也从脆性变为半韧性或韧性。

The effect of moisture content on the mechanical properties of wood structure

In the last two decades, the utilization of timber in construction has gained increasing attention among researchers and sustainable building designers. Therefore, studies of climate impact on timber structures have been conducted, many of them focusing on the moisture content caused changes in timber. In the present study, four-point bending tests have been performed on three testing groups, containing 30 samples each. The first group has been tested under its natural conditions, while the second and the third groups were fully saturated with water. The third group was glazed with a protection material. The results show the changes in the modulus of elasticity and the modulus of rupture caused by the moisture content increase. In the same time the material behavior changed from brittle to semi-ductile or ductile for some samples.
