This paper presents a new analysis of the classical problem of the lateral buckling under pure bending of a curved beam with circular axis. Although a solution to this problem, and to the corresponding straight beam problem is well-accepted in the literature, the present analysis gives buckling moments which are significantly different than the usually accepted results. The difference arises from an application of new boundary conditions that are shown to be the only boundary conditions consistent with the equilibrium of the buckled beam under a pure bending moment. This new analysis provides generally higher bending moments. A short experimental program was performed, and the results tend to confirm the new analysis.
