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 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. ...
