Mechanical Behavior Analysis Of Steel-concrete Composite Beams With PBL Shear Connectors

Steel concrete composite beams through the concrete slab and steel grider componented by the shear connectors as a whole to withstand the applied forces of artifacts.Shear connectors connect the concrete slab and steel grider,which makes the two work together to improve the mechanical performance,it can give full play to the advantages of the compressive properties of the concrete and the tensile performance of the steel.In this paper,analyzed the mechanical properties of steel concrete composite beams which used the Perforated plate(PBL)as the shear connectors,and mainly studied the mechanical properties of PBL shear connectors.The major work content:Based on the former research,a numerical analysis model of PBL shear connector launched three-dimensional nonlinear test,and test results are compared to verify the correctness of the finite element model,using the model,analyzes the stress and failure mechanism of PBL shear connectors.Based on the finite element model has been verified on the discussed in non perforated rebar case,perforated plate holes on the distribution of holes,hole diameter,hole plate thickness,concrete strength,reinforcement diameter and strength of steel and other factors on the mechanical properties of two kinds of component and the ultimate bearing capacity,provide reference for engineering design.
