FRACTURE MECHANICS ANALYSIS OF BOND BEHAVIOR UNDER DYNAMIC LOADING

The bond between reinforcing bars and concrete under impact loading was studied both experimentally and by the finite element method. The experiments consisted of pull-out tests and push-in tests, under three different types of loading: static, medium rate, and impact. Different concrete strengths (normal and high), types of fibers (polypropylene and steel), and fiber contents were considered. This study focused on the bond-slip relationships, and the fracture energy in bond failure. It was found that higher loading rates, higher concrete compressive strengths, and the addition of steel fibers had significant effects on the bond resistance, the fracture energy and the bond stress-slip relationship, especially for the push-in case.
