Experimental Investigation on Ultimate Load-Bearing Capacity of PBL Shear Connectors

    Abstract
  • A test was carried out to investigate the characters of perfobond rib(PBL) shear connectors subjected to combined tension and shear background stresses.Twelve specimens of PBL shear connectors,sorted into 4 groups,were designed,and their ultimate load-bearing capacities and slipping behaviors were investigated experimentally.The experimental result shows that the ultimate load-bearing capacities of PBL shear connectors are influenced by the strength of steel,the tension strength of concrete,the diameter of holes in the steel slabs,the diameter of rebars and the type of background stress.The above-mentioned factors can be combined as the dimensionless load and dimensionless resistance of PBL shear connectors,and the relationship between the dimensionless load and the dimensionless resistance can be denoted by a linear equation.Such an equation can be fulfilled to determine the ultimate bearing capacity of PBL shear connectors.Furthermore,compared with a tension background stress,a compressive background stress can increase the load-bearing capacity of PBL shear connectors.
