- Abstract
This paper proposes a hysteresis model for the perfobond rib shear connector (known as a PBL shear connector) to decrease its mechanical behavior under cyclic loading. A total of 12 PBL shear connector specimens were designed with variable dimensions. The hysteresis curves of all specimens were obtained under cyclic displacement. On the basis of the results, a four-line skeleton curve is developed to reproduce the skeleton curve. Equations for calculating the featured shear resistances and slippages are then proposed, and energy-based cyclic deteriorations are adopted. Four types of deteriorations are specified: fundamental strength; post-peak strength; unloading stiffness; and accelerated reloading slip. Double friction-slip axes are developed to reproduce the pinching effect. According to a comparison of the calculated and tested results, the proposed model can reproduce the hysteresis model of PBL shear connectors under cyclic loading.
