• Abstract: In construction with structural hollow sections the members are generally welded directly to each other and, as a result, member sizing has a direct effect on both the joint capacity and the cost of fabrication. In order to obtain a technically secure, economic and architecturally pleasing structure, both the architect and design engineer must, from the very beginning, be aware of the effects that their design decisions will have on the joint capacity, the fabrication, assembly and the erection of the structure.
  Structural hollow sections have a higher strength to weight ratio than open section profiles such as I-, H- and L- sections. They also require a much smaller weight of protection material, whether this is a fire protection or corrosion coating, because of their lower external area.
  A properly designed steel construction using structural hollow sections will nearly always be lighter in terms of material weight than a similar construction made with open section profiles and, although structural hollow sections are more expensive than open section profiles on a per tonne basis, the overall weight saving of steel and protective coatings will very often result in a much more cost effective construction.
  This publication has been produced to show how the joint capacity of staticaly loaded joints can be calculated and how it can be affected by both the geometric layout and the sizing of the members.
