Abstract

Abstract

In order to overcome the performance deficiencies of the traditional notched connection and dowel connection,a prefabricated composite connector with screw and reactive powder concrete (RPC) coating was proposed. The push-out test results showed that the slip stiffness and shear bearing capacity increased as increasing of the thickness of RPC cover. The main influence factor for the shear behavior of the connection was the outside diameter instead of the diameter of the screw. The proposed connection had the advantages of high stiffness,high ductility and easy assembly. The four-point bending test was carried out on 2 assembled glubam-concrete composite (BCC) beams with composite connectors.The results showed that the flexural behavior of the assembled BCC beams could be attributed to the partial composite action, corresponding that the connectors near the end of BCC beam exhibited relatively large shear deformation. The BCC beams also showed obvious signs before failure due to the excellent ductility of connection. Vertical anti-pull-out measurement of the composite connector was also reliable. Lightweight-concrete overlay could obviously improve the flexural stiffness and bearing capacity of BCC beams without significantly increasing self-weight of BCC beam. The γ-method, provided by Eurocode 5, was selected to evaluate the bearing capacity of the BCC beams, and the predicting results were significantly higher than the test data. Therefore, the γ-method is not suitable for BCC beams.
