Design of steel arches

摘要

Few steel structures design codes provide procedures for designing steel arches against in-plane or out-of-plane failure, despite the increasing amount of research that has been carried out over the past 20 years. This paper uses recent and current research carried out at the University of Sydney on pin-ended circular arches of I-section with the web in the plane of the arch to develop tentative design procedures that are consistent with the Australian limit states design code AS4100. The methods of analysis which might be used to determine the distribution of the in-plane design bending moments and axial forces in the arch are discussed, and then recommendations are made for the nominal section and in-plane and out-of-plane member capacities.
