Abstract
The paper presents aspects related to the verification of the general stability of the bridge superstructures on circular arches with rigid vertical hangers, bridges of open-type or free-standing, without upper bracing.
A numerical worked analysis is carried out for a single-track railway bridge with a span of 30 m, which is based on the normative SR EN 1993-2:2007. Eurocode 3: Design of steel structures. Part 2: Steel Bridges (EC3-2).
The worked analysis carried out can be useful in deepening the knowledge of the procedure presented in the normative, as well as in the designing of the structures on arches in the field of bridges or other types of metal structures.
