Description

This paper presents the design and push-out test results of T-Perfobond connectors. The shear connectors were made with two different geometries by varying the connector flange thickness. The TPerfobond connectors presented two web holes and were immersed into 120mm thick concrete slabs. Reinforcing steel bars were used inside the web holes to increase its structural performance. A numerical study was also made to aid the shear connector design aiming to increase its associated deformation capacity. The results indicate that the developed T-Perfobond connector possessed an appropriate structural behaviour and was also able to achieve the Eurocode 4 [1] ductility requirements.
