Abstract: Nailed strip shear connectors are presented as an alternative to welded headed stud connectors for composite beams. The strip shear connector has a trapezoidal shape to fit the geometry of metal decks. The strips are fixed by means of powder-actuated fasteners.
The legs and the crests of the strip connector are equipped with openings to improve anchorage of the strip in the concrete plate by activating concrete dowels. By means of these openings the overall ductility of the system is improved. The connectors are designed to be used with automatic installation systems to improve installation efficiency.

The objectives of the push-out tests were to derive design parameters and to optimise the geometry of the strip shear connector. The test results indicate that optimised strip shear connectors will achieve high ultimate resistance in the range of 20 kN per fastener and sufficient ductility to allow plastic beam design. Further series of push-out tests are necessary to verify this behaviour statistically and to derive the characteristic resistance.
