Abstract: A flexural‐torsional buckling theory for circular arches of doubly symmetric cross section is developed. Nonlinear expressions for the axial and shear strains are derived, and these are substituted into the second variation ...

Abstract: A finite element method for predicting the inelastic lateral buckling loads of continuous steel beam‐columns is described. A series of tests on three‐span continuous beam‐columns reported elsewhere is studied using the ...

Abstract: Directed loading may have significant effects on the buckling resistances of beams and columns. Rotations of directed loads during buckling induce transverse components that may stabilize or destabilize the member. Previous ...

Abstract: The effect of web distortion on the lateral buckling of I-beams whose top flanges are unrestrained at seat supports is studied by using a finite element method. The theoretical predictions are shown to agree well with ...

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 flexural‐torsional buckling theory is developed for arches of monosymmetric cross section. Nonlinear strain‐displacement relations are derived for the axial and shear strains, and these are substituted into the second ...

Abstract: Flexural‐torsional buckling tests on circular aluminium arches of doubly symmetric I‐sections are described. The arches are fabricated by bending straight specimens to the required radius of curvature in a rolling machine. ...
