Abstract
Different types of shear connectors, which are used for achievement of steel-concrete composite action, have been developed during decades. Their suitability for various range of structures and loadings is determined by shear resistance, ductility of shear connectors, obtained failure mechanisms and fatigue resistance. Headed studs are widely used for composite construction of buildings and bridges. Perforated shear connectors, mechanically fastened shear connectors or bolted shear connectors with mechanical couplers are alternative solution for achievement of composite action between steel and concrete. Results of experimental and numerical analysis of these types of shear connectors are used for comparative analysis and presented in this paper. Presented analysis included comparison of stiffness and different failure mechanisms for these types of shear connections, with focus on the ductility at different load levels. Besides, results are compared with recommendation given in E...N 1994-1-1 for ductile shear connectors.
