heal.abstract	The objective of this paper is to propose improved expressions for the effective buckling length coefficient of columns in multi-story sway, non-sway and partially-sway frames. To that effect, a complete set of rotational stiffness coefficients is presented, which are then used for the replacement of members converging at the bottom and top end of the column in question by equivalent springs. All possible rotational and translational boundary conditions at the far end of these members, as well as the eventual presence of axial force, are considered. Analytical expressions are then proposed for the calculation of the effective buckling length coefficient, covering sway, nonsway as well as partially sway multi-story frames. Examples of multi-story frames with sway, nonsway and partially sway behaviour are presented, where the proposed approach is found to be in excellent agreement with finite element results, while application of Eurocode 3 and LRFD lead to significant inaccuracies. © 2004 Taylor & Francis Group, London.	en
