EXPERIMENTAL RESEARCH ON THE MECHANICAL PROPERTIES OF SHEAR CONNECTORS FOR COMPOSITE BEAM BRIDGE

Full Article:

Two 1:2 reduced-scale model tests with different types of shear connectors are conducted to study the mechanical properties of shear connectors for a composite beam under complex stress conditions. The strain of the shear connector and relative slipping on the steel-concrete interface of the rigid shear connector model and flexible shear connector model under the same boundary conditions is measured. Responses of two types of shear connectors under three different load cases are compared. The test results show that the ultimate bearing capacity of concrete is the key factor of relative slipping on the steel–concrete interface, and differences between rigid and flexible shear connectors are large.
