The sensitivity of thin-walled compression members to column axis imperfection

Abstract Imperfection sensitivity of thin-walled compression members to initial waviness of the composing walls and to imperfection of the column axis was demonstrated in Ref. [1]. The effect of the latter imperfection however was not adequately analyzed. The present report gives the correction and evaluates in the case of an idealized column the reduction of the failure load due to this kind of imperfection, which appears to be significant. Elastic behaviour has been assumed.
