Abstract: To analyze the influence of concrete damage on FRP confined concrete, 264 test data was collected from published literature, and a large database was established, which contains cross-sectional shapes, damage types, and damage levels of specimens, and FRP confined stiffness. Based on the database, the existing lateral strain-axial strain relationship models were evaluated, and a new lateral strain-axial strain relationship model of FRP confined pre-damage concrete columns was established by modi... More
