摘要
方、矩形管桁架弦杆和腹杆大都采用方、矩形管的形式,但当桁架跨度和其上作用的荷载较大时,弦杆受力将较大,当没有合适的方(矩)形管时,在设计中可以采用宽翼缘弦杆和方(矩)形管腹杆组合的桁架形式。通过工程实例介绍了此类桁架节点设计方法,可供设计人员参考。
Although chords and bracings of HSS trusses mostly adopt square or rec t angular hollow sections, when span of truss is large and loads are great, the fo rce of a chord will be accordingly heavy. So trusses composed of wide flang e c hords and square (rectangular) tubular bracings can be adopted in design. Based on projects, joint design methods for this kind of truss have been introduced i n the paper.
