Abstract : A bond model is developed to describe the inelastic behavior of the bond between reinforcing bars and concrete. The bond model is applicable to both monotonic and cyclic loading conditions. It is based on classical non-associative, elasticity-plasticity theory. The model is calibrated by considering available experimental bond studies for short embedment length bond tests. There is good quantitative agreement between the predictions of the bond model and the results of several published bond pull-out tests with steel bars. The tests vary significantly in specimen configuration, concrete strength, and bar rib geometry. (MM)
