✦ Synopsis

The design of thin-walled beam-columns must take into account the overall instability and the instability of component plates in the form of local buckling. This investigation is concerned with interactive buckling of thinwalled beam-columns with central intermediate stieners or/and variable thickness under axial compression and a constant bending moment. The columns are assumed to be simply supported at the ends. The asymptotic expansion established by Byskov andHutchinson (1977: Byskov, E. and Hutchinson, J. W. (1977). Mode interaction in axially stiened cylindrical shells. AIAA J., 15(7), 941±948) is employed in the numerical calculations performed using the transition matrix method. The present paper is a continuation of the papers by Kolakowski and Teter (1995a,b: Kolakowski, Z. and Teter, A. (1995a). Interactive buckling of thin-walled closed elastic column-beams with intermediate stieners. Int. J. Solids Structures, 32(11), 1501±1516; Kolakowski, Z. and Teter, A. (1995b). In¯uence of local post-buckling behaviour on bending of thin-walled elastic beams with central intermediate stieners.
