Abstract
Appropriate evaluation of effective length is important in the buckling design of steel structures. Recently, eigenvalue analyses of overall structures have frequently been used as a method for the calculation of effective length. However, depending on the type of structure, the effective length obtained by this method does not produce rational values, and this sometimes presents a problem. Some methods have been proposed for the modification of this analysis. In this study, the effectiveness of this modified procedure is evaluated by means of numerical evaluations. Discussion on the application of eigenvalue analyses to an overall structure is presented, and a rational method for the calculation of effective length in practical designing is proposed.
