Title:	Analytical modelling of bond stress at steel-concrete interface due to corrosion
Abstract:	An analytical model is proposed for bond stresses at the corroded steel-concrete interface in reinforced concrete. The concrete around the corroded bar is modelled as a thick-walled cylinder - consisting of an inner cylinder of an anisotropic material and an outer cylinder made of an isotropic material - subjected to internal pressure exerted by the growth of corrosion products on the concrete wall at the interface. A frictional model is used to combine the action of confining pressure due to radial pressure produced by principal bar ribs and the pressure resulting from expansion of corrosion products. The analysis results using the proposed model show good agreement with the experimental results of several researchers.
