Analysis of Concrete Beams with Partially Bonded Composite Reinforcement

摘要

Beams prestressed with partially bonded fiber - reinforced plastic (FRP) tendons have high strength and rotation capacity but cannot be modeled by conventional techniques. Herein, it is assumed that all deformation takes place at cracks between rigid bodies. By setting up appropriate compatibility and equilibrium equations, the behavior at a single crack can be modeled, which then allows predictions to be made as to which of four possible event will occur next.
