  • In order to deal with several weaknesses of metal shear connectors such as original crack, welding residual stress and transfering shear capacity intermittently, the performance of organic polymer shear connectors was introduced to study. Eight sets specimens (total 24 specimens) with different adhesive thickness, Young's modulus and interface roughness of organic polymer shear connectors were investigated by push-out test, the ultimate shear capacity and the failure modes were also observed. Considering the main influence factors such as the adhesive thickness, Young's modulus and interface roughness of organic polymer shear connectors, an computational formula on the ultimate shear capacity was proposed. The results show that: organic polymer and concrete sheared together is the main damage form; ultimate shear capacity of organic polymer shear connectors is between 1.10 and 2.47 Mpa,the analysis and test results both show that the shear capacity of metal and organic polymer shear connectors is the same.
