Experimental Studies on Novel Shear Rib Connectors with Powder-Actuated Fasteners
Novel shear connectors are presented as an alternative to welded headed stud connectors for composite beams. They are attached to the beam by means of powder-actuated fasteners. The design of the connectors allows the use of automatic tools to improve installation efficiency. The aim of the development is to achieve high shear capacity per fastener with sufficient ductility to allow plastic design. Various design solutions were tested with pushout tests according to Eurocode 4 (1). The objective of the pushout tests was to investigate the resistance and the ductility of nailed rib shear connectors. One of the designs, the rib connector, consists of two folded angles made from a thin steel sheet. One leg is perforated and embedded in the concrete; the other leg is fastened to the beam by means of powder-actuated fasteners. Based on the test results rib connectors can now be designed to achieve plastic shear behavior and develop characteristic loads of more than 18 kN per nail with a shank diameter of only 4.5 mm.
