A NOTE ON THE EVALUATION OF THE EFFECTIVE LENGTH FACTOR FOR ATRIUM COLUMNS

Abstract

This note examines the evaluation method of the effective length factor of an atrium long column by comparing the formula given in reference [6] with the correct value obtained by performing the buckling eigenvalue analysis given by Takada and Ono in reference [5]. As a result, it is shown that the effective length factor evaluation formula presented in this note can be used to evaluate the effective length factor with an error of about 2.5%.
