Ultimate Strain Model for Confined Concrete with FRP
FRP (fiber reinforced polymer) is a new material to be used for repairing, retrofiring and strengtbening concrete columns in engineering structures. Many theoretical and experimental studies have been carried out on FRP-confined concrete specimens, leading to a variety of models for predicting their mechanics performance. But in these models, only few have been calculated the ductility of confined concrete. In this paper, numerical simulation is adopted to analyze the influence of the concrete compression strength and the confinement stiffness, the FRP tension strength on the FRP-confined concrete through the finite element software-ANSYS. A new ductility model is finally proposed by means of dimension analysis and regression of large text data assembled from existing study overseas.
