Analysis of reinforced concrete elements strengthened by prestressed FRP laminates through non-linear and evolutive models

Abstract

In this paper a non-linear and time dependent evolutive analysis model, previously developed by the authors, is applied to the prediction of the response of reinforced concrete structures strengthened in flexure by FRP prestressed laminates throughout the elastic, cracked and ultimate ranges. The model considers the structural effects of changes in geometry, structural scheme, material properties and applied loads that may occur along the structure service life, including those due to strengthening.
