Effect of dowel shear connector on performance of slim-floor composite shear beams
Abstract This paper presents the numerical modelling and analysis of slim-floor composite beam systems using different shear connector arrangements. A finite element model was developed and validated through comparing the prediction with the results obtained from the experimental study. A parametric study was conducted to examine the effect of typical parameters of shear connectors, including the diameter of the concrete dowel cylinder, incorporating dowel reinforcement and concrete strength, etc. The comparison and analysis further clarified the concrete dowel, mechanism and development of shear resistance and overall load-bearing capacity. The findings based on the numerical simulation provide a deeper insight into the behaviour of this type of slim-floor composite beam system. Through both experimental and numerical studies, the structural merits of this composite beam system were highlighted.
Graphical abstract Display Omitted
Highlights The FE model captures the structural behaviour of slim-floor composite beams. For slim-floor beams using HEB200, the optimum dowel diameter is 80 to 120 mm. Composite beam increases by 2-3% in load capacity if rebar diameter increases by 4 mm.
