轻型木桁架应用及设计

轻型木桁架体系具有施工方便、建筑表现力强、环境友好的特点，在欧美地区应用广泛，国内也逐渐开始有所应用。介绍几个轻型木桁架体系的应用实例，包括普通民用建筑工程、桥梁工程应用及大跨体育场馆。针对目前国内还没有相应的设计规范，介绍TPIC推荐的轻型木桁架设计方法，其内容涵盖：材料、结构形式、结构分析方法、构件及连接验算。

USE AND DESIGN OF LIGHT-FRAME WOODEN TRUSSES

Light-frame wooden trusses were widely used in North America and Europe, due to its environmen- tal friendly, easy for construction and good architectural appearance features. Now it is also accepted by Chinese market gradually. This paper presents an introduction about some classic applications of light-frame wooden truss- es, including conventional residential structure,bridge engineering and large-span sports facility. To date, there is no corresponding design code applicable for Chinese market, so this paper also introduces the TPIC proposed method for MPC truss design, as well as some useful information, including：, dimension lumbers, truss plate, structural configuration, analysis method of wood truss and design formulas for members and joints.
