Abstract

The moment-curvature relationships for steel box sections subjected to compression combined with uniaxial bending moment are presented in this paper. An analytical model for computing the M-P-Φcurves was proposed. In the analysis, residual stress, initial plate deflection and strain hardening were considered. As a result, an interaction strength formula was proposed for locally buckled steel box columns. The moment-thrust-curvature relationship can be accurately predicted by a set of proposed formulas. Moreover, a set of approximate formulas were proposed to predict the moment-thrust-curvature relationship of steel box column segments without local buckling.
