The bond-slip relationship between concrete and steel is very important in evaluating the non-linear behaviour of reinforced concrete structures. In this paper, the problem is analysed for reinforced concrete elements in tension. Two different analytical approaches are applied in order to estimate their performances. This research underlines the importance of bond-slip modeling in a steel post-yielding field by comparison among three well-known, different bond-slip relationships.

Abstract

The bond-slip relationship between concrete and steel is very important in evaluating the non-linear behaviour of reinforced concrete structures. In this paper, the problem is analysed for reinforced concrete elements in tension. Two different analytical approaches are applied in order to estimate their performances. This research underlines the importance of bond-slip modeling in a steel post-yielding field by comparison among three well-known, different bond-slip relationships. Moreover, the results of simple experimental tests on reinforced concrete tensile elements are shown to assess the reliability of previously proposed models in the elastic range and to confirm that an appropriate model for the post-yielding range of behaviour is necessary.
