Plastic design of steel arches

摘要

The in-plane failure modes of steel arches range from the extremes of plastic collapse for stocky arches with significant bending actions to elastic buckling for slender arches in uniform compression. Between these extremes, failure involves an interaction between plastic collapse and elastic buckling which depends on the arch profile, support conditions, loading, and slenderness, and is influenced by geometrical imperfections and residual stresses.
