| Abstract: | In order to accurately evaluate ultimate shear resistance of perfobond(PBL) shear connectors in steel-concrete composite structure,the mechanism and breakage mode of PBL shear connectors were investigated based on the existing push-out test results.According to the push-out test results,longitudinal shear resistance of perfobond shear connectors depends on diameter of holes,thickness of steel plate,compressive strength of concrete,diameter of transverse rebar,yield strength of steel plate,etc.Based on neura... |
