The Use of Fully Threaded Bolts for Connections in Structural Steelwork in Buildings

This paper considers the adoption of standard length, fully threaded fasteners as ordinary (bearing) bolts for general building construction. The potential advantages of such a rationalised choice of bolt are demonstrated, and its behaviour in tension, shear and bearing is considered. It is concluded that such bolts may safely be adopted for beam/column and beam/beam connections and general latticed and framed steelwork, including compression splices with their ends prepared for bearing. It is recommended that further consideration should be given to the additional joint flexibility, as the threads dig into the connected plies, for tension splices and compression splices with the bolts in bearing.
