Confinement Model for Axially Loaded Concrete Confined by Circular Fiber - Reinforced Polymer Tubes

摘要

An analytical model is introduced in this paper to predict the behavior of axially loaded circular concrete columns confined by fiber - reinforced polymer (FRP) tubes. The model is an extension to the confinement model introduced by Mander et al. For concrete confined by steel reinforcement. The model is based on equilib - rium, compatibility conditions, and the biaxial strength failure cri - teria of FRP tubes.
