Abstract

The failure characteristic and load-slip performance of corrugated rib connectors under static load were investigated using the push-out test combined with Finite Element Analysis (FEA). The results obtained from experiment and FEA indicate that the shear bearing capacity of the corrugated rib connectors are closely relate with the key factors including cubic strength of concrete (fcu), the open area of the steel plate (Ac1), perforated rebar tensile yield strength (fy) and Cross-sectional area (Ay), horizontal projection area of corrugated rib (= dwhw). In elastic stage, the overall shear stiffness of the corrugated rib connector are mainly affected by the shear stiffness of the concrete bars. And in elastic-plastic stage, the shear stiffness of the concrete bars and perforated rebar pronouncedly influence the overall shear stiffness of the corrugated rib connector. Finally, a linear model and a power law model for the load-slip behavior at elastic stage and elastic-plastic stage are provided based on the regression statistical analysis, respectively.
