Popis: The rationale for determining the effect of factored loads and member resistances in the beam-column interaction equations of the Canadian standard ‘Limit states design of steel structures’ is presented. These rules are then compared with the design rules used in American, Australian and European codes and the differences and similarities are discussed. In the development of the Canadian standard every attempt was made to embody the actual behaviour of the members in the formulations and to maintain simplicity. Second-order effects are required to be included in the design of frames, although amplified first-order moments may be used under certain restrictions. Column resistances are based on the actual lengths. Notional horizontal loads are applied to the gravity loaded structure to deal with the problem of sidesway stability. The beam-columns are checked against a set of interaction equations related to cross-sectional strength, in-plane behaviour and lateral-torsional buckling.
