Analysis of Pull-out of Shear Connectors in Steel-Concrete Composite Structures Considering Discontinuous Deformation

Abstract The widely used steel-concrete composite structures can fully utilize the high strength of steel and relatively compressive concrete. In service stage structures, shear connectors not only subjected to forces, but also pull-out loading. process is accompanied by crack initiation propagation order accurately analyze discontinuous capacities connectors, a zero-thickness cohesive zone element based on enhanced finite method was simulate concrete in connectors. Then, numerical model connector established, investigated. load displacement curve process, capacity patterns were obtained. deformation during successfully simulated
