Abstract

Abstract

In order to study the influence of new shear connectors on the mechanical properties of steel reinforced concrete columns under axial compression, six short steel reinforced concrete columns with new shear connectors were tested under axial compression with the form and spacing of shear connectors as variable parameters. The failure mode, load-displacement curve, load-strain curve, ductility coefficient and axial force distribution of the specimens were analyzed. The results showed that the setting of stud, π-type perforated panel and π-type CR shear connector had a great influence on the proportion of concrete bearing load in the strong restraint area, and the ductility of the specimens was improved. The ductility of SRCDC-1 with π-type crestbond shear connector was the best and its ductility coefficient was increased by 8.4% compared with the specimens without shear connector. Finally, the bearing capacity of Steel reinforced concrete columns with new shear connectors under axial compression was calculated on the basis of considering the restraint effect of stirrups and section steel on concrete, and relevant calculation suggestions were given.
