Numerical and analytical assessment of the tubular perfobond shear connectors

Abstract

In composite structures, the shear connector is responsible for ensuring the interaction between the materials and their transfer of efforts. Many connectors have been studied, including conventional perfobond, which has excellent resistance but sometimes has limited ductility. Thus, this paper aims to study a tubular cross-section shear connector in order to achieve great resistance, such as a conventional perfobond connector, and suitable slip capacity. The results revealed good mechanical performance, especially in terms of ductility. Varying the strength parameters of the materials improved the resistance of the connectors. However, when the diameter of the holes was increased, the resistance and ductility of the connector decreased. An analytical formulation was proposed, and its result was satisfactorily aligned with the numerical result.
