Experimental and Finite Element Analysis on Behavior of Angle Shear Connectors

Shear connector is a part of steel-concrete composite beam, and it is the key to ensure the whole performance of composite beam. This paper presents the effects of flange and web thickness, height and width of angle shear connectors by using experimental and FE Analysis. 6 push-out tests were carried out to verify the correctness of FE models. In this experiment, the failure mode was the concrete crushing splitting with the angle steels yielded at the junction of web and flange. Specimens had a plastic behavior before failure. As the angle shear connectors concentrate the applied load on the root of flange, the thickness and width of flange and web are the main factors that influence the ultimate strength of angle shear connectors. The height of flange and web could hardly affect the ultimate strength.
