INELASTIC BUCKLING OF BEAM-COLUMNS WITH UNEQUAL END MOMENTS

A semi-empirical model is developed for specifying the pattern of residual stresses in hot-rolled universal i-sections manufactured in Europe and Australia. This model is used to study the inelastic flexural-torsional buckling of beams and beam-columns of differing cross-section with unequal end moments. The study uses a finite element method of analysis whose accuracy has been established elsewhere. The numerical solutions are used to develop a simple method of predicting the inelastic flexural-torsional buckling loads of beams and beam-columns. (Author/TRRL)
