Annotation: 

The paper presents an analytical solution of the stability problem of curved bar elements isolated from a steel arch of continuous section by the flexure-torsion form. The solution uses the deformation theory of calculating plane elastic curved bars of an open profile. The research is based on specific solutions of non-deformation calculation problems and bifurcation stability problems. Graphs of the dependence of the stability coefficients on the fiber yield on the curvature, reduced flexibility, and relative eccentricities are given.
