交叉管桁结构设计研究

A Study of Intersected Tube-truss Structure

目前,钢结构建筑特别是钢结构屋盖得到了飞速发展。基于平面桁架受力清晰、传力路线明确和空间网架的刚度大、整体稳定性好、传力路线短等优点,结合管桁架的特点,提出交叉管桁结构。通过交叉管桁结构算例与其他屋盖结构体系算例的比较,得出这种结构形式受力合理,单位面积用钢量少,具有一定优势。

Steel structure buildings, especially steel roof, are developing rapidly. Based on the advantages oI ptane truss features of clear force, clear force-line, and the large space gird of the tube truss structure, three-dimensional Intersected Tubetruss Structure is proposed. Through the comparative analysis different structures, the author holds that the proposed structure is superior in its strength, economical use of steel per unit, etc.
