Description
Summary:Recent advances in modern construction have led to the frequent use of combined concrete slab and timber beams as a horizontal load-bearing structural component as a result of the development of appropriate connecting devices. Several of such devices are now available, some allow for limited interlayer slip, while others prevent separation of the partial girders. Installation speed and working conditions on site are the two major criteria that dictate their market prospects. The connector described here was developed with the paramount objective of breaking the speed barrier by using modern fixing techniques such as the multi-purpose Hilti cartridge-operated gun. Results from tests show that the new shear connector possesses higher rigidity, ductility and ultimate strength than a limited range of Hilti shear connectors used in both composite wood–concrete and concrete–steel construction.
