Abstract:The bond strength of the plain round bar plays important role in the assessment of historical buildings and has been widely investigated. This paper presents an analytical approach to the bond strength of plain round bars embedded in concrete subjected to lateral tensile stresses. Based on the theory of elasticity, the contact condition of the bar/concrete interface is discussed, and an analytical solution for the ultimate bond strength is further derived. When the shrinkage of concrete, the geometric and mechanical parameters of bars and concrete are given, the analytical solution can be used to evaluate the ultimate bond strength of plain round bars subjected to uniaxial and biaxial lateral tensile stresses. 153 pull-out specimens are used to verify the analytical solution. The results show that, the analytical predictions are in good agreement with the experimental values. ? Avestia Publishing, 2016.
