CALIBRATION OF THE PROPOSED LIMIT STATES DESIGN RULES FOR STEEL BEAMS AND COLUMNS

The probabilistic models of steel beams and columns used in the calibration of the proposed limit states design (LSD) rules for these members are presented. Safety indices are computed for members designed to the existing and proposed LSD rules. The components considered are beam segments with and without lateral support including elastic and inelastic response, and axially loaded columns. Components of variability covered by the models include that due to the design process and the inherent variability of the material, fabrication and section properties. It is proposed that the current differential in safety indices between the two groups of beams be maintained in the proposed LSD code and this could be achieved by using only one phi-factor for all steel beams. Similarly, it is proposed that only one phi- factor be used for hot rolled columns for all slenderness ratios. (Author/TRRL)
