About
A CoSFB-Dowel is an innovative shear connector for steel-concrete composite slim-floor beams. It consists of circular openings drilled in the web of the steel secton with reinforcement bars passing through and filled with normal concrete in-situ. This research projects focused on the identification of parameters influencing the load-bearing behavior in general and on parameters contributing to the load-bearing capacity of CoSFB-Dowels in detail. Detailed analysis of Push-out test results along with finite element simulations led to an improved understanding of the overall load-bearing behaviour. Using the numerical model to identify and evaluate components contributing to stiffness and strength, a mechanical model with an analytical method was developed to evaluate the load-bearing capacity of CoSFB-Dowels.
