Structural behaviour of perforated shear connectors with flange heads in composite girders: an experimental approach
Abstract Perforated shear connector with flange head (PSCFH) as a new type of connector behaves high bearing capacity and excellent ductility in steel-concrete composite girders. In this paper 15 groups, totally 45 push-out test specimens, were conducted to investigate the effects of plate thickness, connector height, flange length, flange number, hole diameter on the web, diameter of reinforcing bars and concrete strength on structural behaviour of PSCFH. In the push-out tests, failure mode, load versus slip curve and bearing capacity of all the specimens were obtained. Based on the results of push-out tests, bearing mechanism was analyzed and a calculation model of the shear bearing capacity was proposed with respect to the failure modes. Calculation results based on the proposed model agree well with the experimental values.
