The theme of this issue of PCI Journal is Connections, so it seems appropriate to discuss a PCI research and development project that pertains to the precast concrete workhorse: the headed-stud connection. In the precast concrete industry, welding headed studs to steel plates and embedding the assembly into the formwork provides an economical means of making connections. After stripping and component erection, other connecting hardware is attached to complete the structural connection in the field. The geometric design of the headed stud closely follows the characteristics of a structural bolt with its hex head or a heavy hex-headed nut embedded in concrete. Headed-stud anchorages can be found in column corbels, spandrel beams, dapped-end members, wall panels, tee beams, and a host of other precast concrete structural components. |
