Abstract

The slipping of a steel bar inserted in a mass of concrete is known to affect the behaviour of reinforced concrete members. A tension-stiffening effect and crack evolution occur from the beginning of slipping; thus, estimating them requires the introduction of a bond-slip interaction model. This work presents a beam-layered model, including the constitutive relationships of materials and their interaction, according to the CEB-FIP Model Code 1990. To eliminate the finite element sub-division procedure, a continuous slip function is imposed into the element domain. The results are continuous descriptions of bond stress in the steel-concrete interface, as well as concrete and steel stresses along the element.
