Abstract
A steel arch may fail in-plane due to excessive bending amplified by in-plane buckling effects, or it may fail by out-of-plane
buckling if it does not have sufficient out-of-plane restraint.
This paper proposes procedures for designing arches against in-plane bending and out-of-plane buckling. The in-plane bending design is based on an extension of an existing set of in-plane beam-column rules for straight members using the in-plane arch buckling load. The out-of-plane buckling design is based on the use of load factors for section capacity determined from existing standard rules and for elastic flexural-torsional buckling to determine a modified slenderness for the arch, and a conversion to design capacity which is based on existing rules for compression members. purchase the full-text of this paper (price £20)
