Temporary works for dismantling steel cantilever truss bridges in the USA
Dismantling steel cantilever truss bridges is a complex operation that requires significant engineering to produce safe and effective dismantling sequences. Such sequences often include a variety of temporary works including temporary truss members, temporary support towers, tension-release devices and temporary attachments for heavy-lift components. This paper provides a review of the design and analysis considerations for developing a dismantling sequence for cantilever steel truss bridges and the design of required temporary works, with three examples from the USA.
期刊介绍：
Civil Engineering, listed by the Web of Science, is the ICE''s flagship journal. Practical and diverse in its scope, it publishes overview papers for the non-specialist on any subject relevant to civil engineering today. Topics range from landmark projects to philosophical, ethical, environmental, management and safety issues.
Peer review, copyediting, and colour publication by Civil Engineering are free. If accepted, published papers are easily found by Google search, as well as in specialist citation indexes. There is also the option of making your article open access, should you wish to.
Published authors receive a free electronic copy of their article to share with their peers. Furthermore, as well exposure to ICE''s 91,000-strong membership, published papers are promoted via our social media channels, accessing the wider civil engineering community.
It is free to submit a paper to this journal. Papers appear Ahead of Print (below) as soon as they are ready to be published. Ahead of print articles are fully citable. using the DOI system
