STABILITY CALCULATION OF ROD ELEMENTS OF SOLID-WALL ARCHES BY THE FLEXURAL-TORSIONAL FORM

Abstract

The work considers main, most significant scientific works on study of the stability of rods with the curved axis; the issue of the subject matter investigation is examined. A procedure for determining the spatial displacements of curvilinear rods during the elastic work of the material is proposed. An for the assessment of the stress-strain behavior of the rod element with the curved axis by the criterion of fibrous yield is given. As the algorithm illustration, an example is given of selecting a section of a steel arch.
