摘要

摘要: 《钢结构设计规范》(GB50017-2003)对钢管桁架中受压腹杆的计算长度没有明确说明，结合国内外的研究成果，利用有限元分析程序，对相贯节点连接的平面钢管桁架中受压腹杆的计算长度进行了计算分析。结果表明:相贯节点平面钢管桁架中受压腹杆的计算长度主要和腹杆与弦杆外部宽度之比、壁厚之比有关。最后给出了受压腹杆计算长度设计建议值。

Abstract: In The Code for Design of Steel Structure ( GB 50017- 2003) , there are no specifications about effective lengths of compressive web members for tubular truss with simple joints. This paper used the program of finite element method, analyzed the effective lengths of compressive web members for the tubular truss. The results indicated that the effective lengths of compressive web members mainly depend on the parameters: and , then gave the relative suggested values.
