The finite element analysis of high-strength concrete columns confined by high-strength spiral lateral ties under concentric compression is introduced in this paper. The variables of tie strength, tie spacing and tie configuration influencing the characteristics of confined concrete are discussed; and the stress distributions of lateral ties and concrete at cross-section are analyzed. Compared with the test results, this finite element analysis can predict well the behavior of axially loaded concrete confined by lateral ties. It’s indicated that after peak load, normal stirrups loss the effective constraint on concrete due to yielding early, while the high-strength stirrups can continue to provide larger constraint which can improve significantly the ductility of confined concrete.
