This research builds on the results of a previous ARC Linkage project in which the research team developed a range of connections between steel beams (or composite steel/concrete beams) and both tubular steel columns and concrete-filled steel tubular columns. All of these connections rely on an innovative "blind bolt" developed by Ajax Fasteners that provides a major economic benefit by requiring installation from one side only.

The aim of the new ARC Linkage project is to develop structural systems that have sufficient stiffness, strength, and ductility to withstand code-specified loads and that will be competitive in the marketplace. The development of demonstrable cost-effective structural systems is essential if these types of systems are to be widely adopted in practice.
