木结构.托梁吊架.试验方法

[中文适用范围]： 本文件提供了用于确定预制三维托梁吊架的垂直载荷、轴向载荷和扭矩能力以及偏转特性的标准测试方法，这些预制三维托梁吊架主要用于将一个木构件固定到另一个木构件上（头部可以是混凝土或砖石） 。 托梁吊架主要将垂直载荷从被支撑构件传递至支撑构件，但也可能需要它们将轴向载荷从被支撑构件传递至支撑构件。 注 1：结构钢型材也可以代替头部，但不在本文件中涵盖。 注 2：要考虑的一种辅助机制是支撑构件绕其纵轴旋转对托梁吊架的影响。 [外文原描述]： This document provides standard test methods for determining the vertical load, axial load and torsional moment capacity as well as deflection characteristics of preformed three-dimensional joist hangers that are used primarily for securing one timber member to another (the header can be concrete or masonry). The joist hangers primarily transfer vertical loads from the supported member to the supporting member, but they can also be required to transfer axial loads from the supported member to the supporting member. NOTE 1 Structural steel sections can also be substituted as the header, but are not covered in this document. NOTE 2 One secondary mechanism to be considered is the effect of rotation of the supported member about its longitudinal axis on the joist hanger.
