木桁架

为了了解木桁架结构的承载能力，对四榀跨度6m的轻型木桁架进行了静力加载试验，通过试验了解了该种木桁架的荷载-变形关系以及可能的破坏形式。

For the purpose of understanding the bearing capacity of light wood truss , the load carrying tests for four light wood trusses with 6 meters span were carried out so as to know the load - deformation relationship and probable failure modes of wood truss .

木桁架有很好的强度-重量比，与传统建筑屋顶或楼面系统安装相比，木桁架更省时，使其为经济的选择。

The wood truss offers a great strength-to-weight ratio , and they take a lot less time to install compared to building conventional roof or floor systems , making them an economical choice .

将这种特殊的考虑角度因素的齿板连接的滑移关系带入模型，通过程序计算，得出模型的杆件内力、木桁架变形以及齿板滑移。

Considering the slip relationship of the special angle factor of metal plate connector in the model , internal force of bar , deformation of wood truss and slip volume of metal plate had been obtained by program calculation .

由于我国缺乏齿板连接的研究与工程积累，规范中齿板连接内容主要参照加拿大规范提出，有的地方还不够完善，因此对齿板连接木桁架的研究有着重要的意义。

As lacking of metal plate joints ' research and engineering accumulation , metal plate joint of our norms is mainly referring to the Canadian norms , it is not consummate , so it is of great significant to study the metal plate truss of the light wood frame construction .
