Limit analysis on FRP-strengthened RC members
Journal Title: Frattura ed Integrità Strutturale - Year 2014, Vol 8, Issue 29
Abstract
Reinforced concrete (RC) members strengthened with externally bonded fiber-reinforced-polymer(FRP) plates are numerically investigated by a plasticity-based limit analysis approach. The key-concept of thepresent approach is to adopt proper constitutive models for concrete, steel reinforcement bars (re-bars) andFRP strengthening plates according to a multi-yield-criteria formulation. This allows the prediction of concretecrushing, steel bars yielding and FRP rupture that may occur at the ultimate limit state. To simulate such limitstateof the analysed elements, two iterative methods performing linear elastic analyses with adaptive elasticparameters and finite elements (FEs) description are employed. The peak loads and collapse mechanismspredicted for FRP-plated RC beams are validated by comparison with the corresponding experimental findings.
