Abstract

This article summarizes the results of 13 push-out specimens under the effect of different loading combinations including shear, torsion and negative bending moment. The objective of the project is to record the reductions in the capacity of the stud shear connector and the change in the behaviour of the composite section when torsion is applied. An equation is presented to calculate the produced axial force in the stud shear connector for sections subject to any loading combination. Modifications are performed to the well-known exponential formula representing the load-slip relation of the studs. Finite element application is conducted to simulate the behaviour of the composite section and the stud shear connector as well. The simulation shows a very good agreement with the experimental results.
