Hysteretic performance of Y-type perfobond rib shear connectors

Abstract

The hysteresis performance of Y-type perfobond rib shear connectors has been investigated with various transverse rebars (D10, D13 and D16). Cyclic loading tests were conducted and energy dissipation and stiffness degradation characteristics were evaluated. Total amount of energy dissipation increases with the diameter of transverse rebars, and stiffness degradation ratio at early stage decreases with increasing diameter of transverse rebars. Y-type perfobond rib shear connectors can be adopted efficiently for seismic performance of composite structure to be improved.
