Over the past few years, several studies have been made on mechanical characteristic of perforated-rib shear connector (PBL) and burring shear connector (BURRING) by push-out test for building structures. The purpose of this study is to examine the effect of BURRING and PBL on bending behavior of steel-concrete composite beams. Full-scale bending tests are performed on four composite beam specimens using BURRING, PBL and headed stud shear connector. The composite beam specimens were designed to be partial composite. It was found from the result that the rigid shear connectors showed a good performance.The results of this experiment will change design of shear connector on steel-reinforced concrete joints.
