Hybrid connection technologies for hollow sections in steel construction

Circular hollow sections (CHS) offer a variety of constructional and architectural advantages. Up to now, section structures have usually been connected by welding, more rarely bolting. However, these established connection methods disadvantages. Despite its great success in the mobility sector, adhesive bonding is not yet used for joining steel construction. Adhesive bonding, however, has significant advantages, especially if combined with classical processes. To highlight this article presents excerpts from results obtained two recently completed research projects. First, hybrid brace framework presented which combines bolting methods. In addition, loadbearing behaviour novel grouted connection, advantageously grout materials, analysed discussed paper.
