A parametric analisys of composite beams with t-perfobond shear connectors

摘要

This paper presents the design and push-out test results of T-Perfobond connectors. The shearconnectors were made with two different geometries by varying the connector flange thickness. The TPerfobondconnectors 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 numericalstudy was also made to aid the shear connector design aiming to increase its associated deformationcapacity. The results indicate that the developed T-Perfobond connector possessed an appropriatestructural behaviour and was also able to achieve the Eurocode 4 [1] ductility requirements.
