The effective column length and buckling strength of tubular truss members are disscussed based on the experimental results reported in the previous paper (Part 1). Significant conclusions drawn from this study may be summarized as follows : (1) Axial forces of members can be calculated assuming that joints are hinged until one of the web members buckles. (2) Buckling loads evaluated from the test agree well with results of a theoretical analysis, which is based on the tangent modulus theory ignoring secondary bending moments. (3) The, buckling strength can be predicted with sufficient accuracy by using effective length factors determined by the elastic analysis unless the stiffness of joints deteriorates due to extensive yielding.
