Limit analysis on FRP-strengthened RC members
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 the present approach is to adopt proper constitutive models for concrete, steel reinforcement ba...

| description | 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 the
present approach is to adopt proper constitutive models for concrete, steel reinforcement bars (re-bars) and
FRP strengthening plates according to a multi-yield-criteria formulation. This allows the prediction of concrete
crushing, steel bars yielding and FRP rupture that may occur at the ultimate limit state. To simulate such limitstate
of the analysed elements, two iterative methods performing linear elastic analyses with adaptive elastic
parameters and finite elements (FEs) description are employed. The peak loads and collapse mechanisms
predicted for FRP-plated RC beams are validated by comparison with the corresponding experimental findings. |
