摘要
In the finite element analysis of reinforced concrete structures for modeling of bond-slip between the reinforcement and concrete requires the use of special elements. In the past, various elements have been developed for this purpose. The behavior of the elements and the quality of the results are influenced mainly by the displacement function of the elements, the density of the element mesh, and the bond stress-slip relations. In this paper the effects of different approaches for the displacement function and the bond stress-slip relation are investigated.
