前言木结构设计规范根据《建筑结构设计统一标准》进行了修订。在设计数据、单位、承载力表达式、基本设计规定等方面都有某些更改。因而螺栓连接亦应该与之密切适应。结合规范修订工作的需要,近年来又进行了东北产红松、四川产冷杉圆钢销连接的试验,对销连接的工作特点及变异性的认 Foreword The wood structure design specification has been revised in accordance with the “Unified Standard for the Design of Building Structures”. There are some changes in design data, units, bearing capacity expressions, basic design rules, and so on. Therefore, the bolt connection should also be closely adapted to it. In order to meet the requirements of the normative revision work, in recent years, experiments have been conducted on the connection of Pinus koraiensis and Sichuan-made fir round steel pins in the northeast, and the working characteristics and variability of pin connections have been recognized.
