Development of a Plasticity Bond Model for Reinforced Concrete - Theory and Validation for Monotonic Applications

Abstract

Reinforced concrete modeling requires models for the constituent materials, concrete and steel, and for their interaction which is called bond. This study's objective is to develop and validate a monotonic bond model that, at least qualitatively, reflects the micromechanics and yet has potential application in the numerical analysis of structures or their components. A plasticity bond model is derived from simplified analyses of selected experimental results. This model relates local slip and radial dilation to bond stress and radial confinement stress. It represents the response of a finite-thickness region around the bar called the bond zone. The resulting model only requires knowledge of two fundamental properties of the concrete and two geometric properties of the reinforcement, and yet is able to reproduce the results of six independent experimental studies with acceptable accuracy.
