摘要
将新修订的《钢结构设计规范》GB 50017-2003中框架体系支撑条件的区分引入到错列桁架的稳定分析中,考虑初始缺陷的影响,提出了强、弱支撑错列桁架体系的划分标准,推导出了错列桁架体系柱子平面内计算长度公式。强支撑体系中柱子计算长度可以按照规范GB 50017-2003计算;对弱支撑体系,提出了柱子计算长度的实用计算公式。
The discussion of flame bracing condition that exists in the new vision （Code for Design of Steel Structures）GB 50017 -2003 has been lead into the stability analysis of staggered truss system. Considering the effect of initial deflection, the concrete dividing standard of strong and weak bracing staggered truss system are also given. The column effective length of strong bracing system can be calculated according to current design code. For weak bracing system, this paper provided the concrete formula of calculating the effective length coefficient of column.
