Progress in research on shear resistance of demountable shear connectors
In the composite beam structure,the demountable shear connectors play a role in the shear transfer between the steel beam and the concrete slab.The composite beam structure can achieve rapid replacement and restore the normal use function of the structure after damage or service period by replacing the demountable shear connectors.Demountable shear connectors are considered to be an effective solution for the sustainable development of composite bridges and buildings in the future.The types,failure modes,shear bearing capacity,stiffness and ductility of demountable shear connectors were reviewed,and the existing problems of demountable shear connectors and the prospect of future research on demountable shear connectors were proposed.
