Overview of Loading Rate Sensitivity of the Bond Stress-slip between Reinforcing Steel Bars and Concrete

This article provides a brief summary of a large number of research literature of domestic and foreign about the loading rate sensitivity of bond behavior, systematically introduces and analyzes the research achievements in the field of experimental investigations about dynamic bond behavior. On this basis, with respect to some essential problems in the field of the research of the rate sensitivi- ty of bofld behavior, the author puts forward some suggestions on further research and some critical problems that should be paid much more attention to in order to get a better understanding of the effect of loading rate on the bond stress-slip behavior. In addition, this article also introduces three test devices which are widely used in dynamic test to get relatively higher loading rates.
