The challenges posed by designing such an ambitious project in a city location led to a myriad of structural options being considered. The selected option for the River Irwell span was an 89m single-span network arch bridge. On completion, the bridge will not only be the first network arch bridge in the UK, but also the second-longest in the world to carry twin heavy-rail tracks.
This article gives an overview of the initial design processes that led to the proposition, recommendation and selection of the network arch-type bridge for this particular span within the overall system.
This month we bring you another question from the Institution’s Structural Behaviour Course. The topic is indeterminate bending moment diagrams. Answers will be published in the August issue.
In this section we shine a spotlight on papers recently published in Structures – the Research Journal of The Institution of Structural Engineers. Structures is a collaboration between the Institution and Elsevier, publishing internationally-leading research across the full breadth of structural engineering which will benefi t from wide readership by academics and practitioners. Access to Structures is free to Institution members (excluding Student members) as one of their membership benefits, with access provided via the “My account” section of the Institution website. The journal is available online at: www.structuresjournal.org
Upcoming events at HQ and from around the regional groups.
