Abstract:
An analytical computerized method is presented which is capable of directly and easily determining the distribution of steel stress, concrete stress, bond stress, and steel-to-concrete slip along a steel bar inserted in a mass of concrete. The method can deal with generalized cyclic loading, assuming appropriate constitutive curves for steel and concrete and focal-bond to local-slip relationships. A series of analytical applications is given regarding pullout tests under monotonic loading, and axially loaded elements under both monotonic and cyclic loading. Finally, flexural members are also analyzed employing suitable simple models, and their moment-curvature curves are obtained under reversed bending.
