Abstract

Abstract

A total of 10 high-strength concrete columns confined by high-strength stirrups were tested under eccentric loading.The test parameters included the arrangement,spacing of confinement reinforcement and the eccentricities.Test results indicate that,columns confined by stirrups with small spacing and high strength show extremely ductile behavior.Also the experimental column capacities are well above the analytical capacities indicated by the interaction diagrams based on the code.The analytical moment-curvature curves obtained using confined concrete model are in good agreement with the experimental ones.
