A concrete damage–plasticity model for FRP confined columns
Abstract Proper design of fibre reinforced polymer (FRP) retrofitted concrete columns requires an appropriate concrete model that describes both confinement sensitivity (i.e increase of the strength and ductility) and dilation characteristic of concrete under the triaxial stress state. In this paper, a confinement-sensitive damage plasticity model for concrete material is developed. The dilation behaviour is predicted using a non associated Cam-Clay type potential function. The application of the model is demonstrated in the case of actively and FRP confined (passive) concrete. It is found that essential mechanical features of the confined concrete can be reproduced for both actively and passively confined concrete in practical engineering uses.
