Abstrakt:

Load carrying capacity of perfobond shear connectors in steel-concrete hybrid structure are focused on in this paper. Mechanical behaviour of a perfobond shear connector is influenced by various parameters in steel-concrete structure. To evaluate the behaviour of perfobond shear connectors, push-out tests were carried out. In the experimental program, 24 push-out tests of connectors with 20 mm thickness and with 8 mm thickness, both in different opening and with different transverse reinforcement were accomplished. Based on the load-slip relation of connectors, connection behaviour was analysed and failure mechanism was identified and the load capacity, maximum slip and shear stiffness were quantified. The results of these tests have shown that failure mode of perfobond shear connector changes with different thickness of the perforate plate. Including shear failure of perforate plate, flexural and shear failure of transverse rebar and shear failure of the transverse rebar, three main failure modes of shear connector may occur.
