Finite Element Modelling of Reinforced Concrete Structures Strengthened
with FRP Laminates
Final Report, SPR 316. Oregon Department of Transportation, (May 2001)Abstract
Linear and non-linear finite element method models were developed
for a reinforced concrete bridge that had been strengthened with
fiber reinforced polymer composites. ANSYS and SAP2000 modeling software
were used; however, most of the development effort used ANSYS. The
model results agreed well with measurements from full-size laboratory
beams and the actual bridge. As expected, a comparison using model
results showed that the structural behavior of the bridge before
and after strengthening was nearly the same for legal loads. Guidelines
for developing finite element models for reinforced concrete bridges
were discussed.
