Span-by-Span Erection of Precast Segmental Bridges: Twin-Girder Overhead Self-Launching Gantries

Marco Rosignoli

4.9/5 (15753 ratings)

Description:The vast majority of precast segmental bridges are erected span-by-span with overhead and underslung self-launching gantries. Twin-girder overhead gantries provide unrivalled flexibility of operations in large-scale highway bridges, light-rail transit bridges with box girders and dual-track U-spans, urban bridges in median, marine operations and other conditions of reduced clearance under the bridge. The eBook explores the main components of a twin-girder overhead gantry, the pros and cons of modular trusses and box girders, the use of hangers and spreader beams for the precast segments, and the support, launch and lock systems of the gantry. It also discusses loading, self-launch kinematics, performance, productivity, the span cycle time, the labor demand for the different solutions of staged construction, and the pros and cons of simultaneous erection of adjacent bridges by side shifting the gantry from bridge to bridge. Fully integrated within the Bridge Engineering eManuals © project, the eBook explores the progressive instability induced in tall bridge piers by pier brackets supporting the front pendular leg of the gantry, the stiffness interactions to consider for the design of bridge piers and superstructures, and staged application of post-tensioning to avoid opening of the epoxy joins and the risk of brittle span failure during span release. The Bridge Engineering eManuals © project provides exhaustive coverage of new and emerging bridge construction technology and modern construction methods for all bridge professionals looking to save time, labor and costs, reduce risk, and increase the value and quality of bridge projects through mechanized construction. The eManuals share format and print styles to be collected into customized books, are immediately downloadable in PDF format from the author’s website and as Kindle Editions from Amazon, and deliver a unique wealth of knowledge and learning. Extracted from the bestseller “Bridge Construction Equipment” (2013, ICE Publishing) and the second edition of “Bridge Launching” (2014, ICE Publishing), the eManuals expand the discussion from the 2-day classes of bridge launching and bridge construction technology that the author teaches for the Continuing Education Program of the American Society of Civil Engineers (ASCE) and face-to-face in the offices of bridge owners, designers and constructors to provide exhaustive coverage of the topic.We have made it easy for you to find a PDF Ebooks without any digging.
