Composite Beams with Web Openings Employing Alternative Layout of Shear Connectors

It is generally accepted that bearing systems consisting of composite elements, combining steel and concrete, are highly efficient. Nevertheless, the current economic situation generates continuous demand for more effective solutions. Hence, by the finite element model, this paper investigates an impact of alternative layout of shear connectors adopting a combination of continuous and discontinuous distribution. On the basis of numerical investigation, the study seeks an optimal layout of shear studs for simply supported composite beams under uniform static loading utilizing the same number of connectors for each span. The paper is divided into three parts. At first, investigated specimens are designed against European Standards and limitations according to the literature. This is followed by a parametric study using finite element models examining shear flow magnitudes at the steel-concrete interface and plastic strain evolution at the level of the bottom flange. Afterwards, the study reveals relations regarding the modified parameters and overall structural performance of composite girders. Despite that, the paper is unable to encompass the entire matter of issue but serves as a preliminary attempt to define a novel structural connection arrangement presenting more unit utilization of composite beams' resistance.
