| 摘 要： | 在详细分析各国现有试验资料的基础上,提出了用于平面桁架设计的等效长细比计算公式,其主要特点是可以直接计算不同强度等级角钢压杆的长细比,提出了连接肢宽厚比限值的计算公式。分析结果表明：设计单边连接的单角钢压杆,除正确计算外,还应考虑构造措施的影响,并且腹杆应该配置在弦杆同一侧;节点连接板的厚度、连接肢的宽厚比等也需要有所考虑。

| Abstract: | Based on analyzing the available test data in detail, the calculation formulae of equivalent slenderness ratio which were used in planar truss design were put forward. The feature of these formulae lied in giving directly reduced slenderness ratio for angle steel of various strength grades. Beside correct calculation, the analytical results show that the effects of constructional measures have to be considered in designing single-angle steel struts connected by one leg except for correct calculation. Web members can be laid on a same side of the chord, the thickness of gusset plate and the width-thickness ratio have to be concerned. These issues are discussed and calculation formulae of width-thickness ratio limiting values of connecting leg are proposed. |
