Abstract: Present methods for approximating the elastic lateral buckling load of a continuous beam are unnecessarily conservative when the beam is loaded by concentrated moments. This is because the significant warping restraints ...

Abstract: A finite‐element method of analysis is presented for the elastic flexural‐torsional buckling of non‐prismatic I‐section beam‐columns. The formulation presents a general approach to the problem, in which the coupling of ...

Abstract: An accurate line model based on the finite‐element method is developed for analyzing the inelastic lateral buckling of I‐section beams and beam‐columns. The prebuckling in‐plane bending is analyzed using a geometrically ...
