ABSTRACT

Beam-columns are members with compressive axial forces and transverse loads or moments. Beam-columns which are bent in a plane of symmetry may fail by excessive bending in that plane, or may buckle out of the plane by deflecting laterally u and twisting (/>. This flexural-torsional buckling behaviour is an interaction between the buckling behaviour of columns discussed in Chapters 5 and 6 and that of beams discussed in Chapters 7 and 8 and extended to cantilevers in Chapter 9 and braced and continuous beams in Chapter 10.
