Elastic column stability in multi-storey frames

Column design methods for multi-storey frames commonly used in North America are based upon two nomograms prepared by Julian and Lawrence. The various assumptions behind the equations of these nomograms necessitate a realistic review of the effective column length factor which defines the load carrying capacity of the column. For multi-storey frames subjected to gravity and lateral loads, a theoretical solution based on matrix formulations has been developed. Experiments were done on an aluminum framework designed to verify the behaviour of the multi-storey frame and the columns as a part of the frame. The behaviour observed for different loading patterns is compared with the theoretical solution using a proportional multiplier of load as parameter. The Southwell plotting technique, is applied to find the critical loads of column members in the loaded frame. Comparisons with the present code are given for interior, exterior and tier columns.
