Abstract
This paper deals with probabilistic strength analysis of steel beams and columns. Analytical method is presented, using basics trength formulate of beam and column which are derived semi-theoretically and adopted as performance functions of beam and column strength. Yield stress of material, residual stress and initial out-of-straightness of steel member are treated as stochastic variables. Analytical expressions of probability density function of beam and column strength are represented. Analytical results are compared with ECCS and SSRC multiple column curves and experimental data of beams.
