摘　　要：GB/T 50329-2002《木结构试验方法标准》,对木结构梁的抗弯试验及剪切模量测试用U型挠度架装置,仅提出刚度要求,未涉及材料、构造等内容。笔者针对胶合木梁的抗弯性能测试,设计两种尺寸的U型挠度架,并将其应用于木梁抗弯性能测试。根据试验结果,阐述挠度架的材料选择、结构设计以及应用要点。In the Chinese national standard for Timber Structures Testing Methods,GB/T 50329-2002,U-type supports are specifically required to measure wood deflection during bending tests.However,the standard did not present details for how to choose the materials or how to design a U-type deflection support.The authors of this article developed two U-type deflection supports with different configurations.The design details and user instructions for the supports are described.

关 键 词：木结构梁 抗弯试验 挠度架
