| 摘 要： | 钢结构交错桁架体系中,桁架上、下弦均需搁置楼板,其腹杆与下弦连接节点板的强度与稳定性验算需分施工和使用两个阶段分别按照不同的条件计算。比较了中国钢结构规范和美国钢结构交错桁架设计指南中关于节点板计算的办法,推荐了交错桁架结构中桁架节点板的计算方法,比较了中、美规范所得结果的差异。算例计算表明,推荐的计算方法简洁实用。

| Abstract: | The strength and stability checking computations of the gusset plate which combines the web member and the truss bottom chord include two part: constructing phase when the precast plank hasn't emplaced on the chord and using phase when the precast plank has emplaced on the bottom chord.It's different from common steel truss system.This paper analyzes the design expressions about the gusset plate in the Code for design of steel structures of China and the Steel design Guide Series Staggered Truss(Framing) systems of America.It indicated that the calculate method by stages be the most practical and handy one for the calculation of some actual gusset plates. |
