Abstract

Composite structures have been successfully used in the construction of bridges and buildings as they present notable structural and constructive advantages over traditional reinforced concrete and steel systems. In steel-concrete composite beams, the joint action of the beam with the slab – which aims to exploit the main virtues of the two materials – is guaranteed by shear connectors. The stud-bolt is currently the most used connector in the world. However, the need to use specific equipment for welding makes its use difficult, especially on remote construction sites. To offer an alternative with good structural performance, low cost and easy execution, the Truss-Type shear connector was developed. In this study, a methodology was developed to numerically simulate the mechanical behavior of the Right-angle Truss-Type shear connector. Therefore, a parametric study was carried out in order to evaluate the influence of varying the connector height on its resistance. The results indicated that the use of linear finite elements in connector modeling provides good results and a significant reduction in computational cost.
