Abstract

Abstract

By ANSYS program analysis,stability capacity was computed for circular tube beam-columns under axial compressive force and various biaxial end-moments with different distributions.The comparison of numerical results with the interaction formula in current design code GB 500172003 shows relative big errors.An improvement is presented,and the proposed interaction formula can be applicabe with high accuracy.
