LATERAL-TORSIONAL BUCKLING OF NONPRISMATIC I-BEAMS
The authors of this technical paper develop a finite-element formulation for the lateral-torsional buckling analysis of nonprismatic I-beams. The formulation can be used to analyze continuous I-beams with a linear or quadratic taper within acceptable accuracy. The influence of warping deformations of the section and location of the member loads at different cross-section points are included in the formulation. Finite-element solution convergence is examined based on available experimental and numerical results. A parametric study on the lateral-torsional buckling strength is performed for different forms and degrees of taper, loading, and support conditions for single-span and two-span continuous beams. The buckling strength of beams with various degrees of taper and number of spans are also studied.
