Shuhei HARA, Masae KIDO, Keigo TSUDA
The purpose of this paper is to propose a formula for evaluating an effective length factor of a column subjected to lineally varying axial force. The boundary condition of the column is simply support or fixed end at both ends. Analysis is performed by using the energy method and the assumed buckling mode is obtained by the trial and error method. Moreover, the effective length factors prescribed before are compared with proposed one. It is shown that the evaluation accuracy for the effective length factor is high.
