Span-by-Span Erection of Precast Segmental Bridges: Introduction

Marco Rosignoli

4.9/5 (27905 ratings)

Description:Span-by-span erection is the most diffused and often the most cost-effective construction method for precast segmental bridges. Initially conceived for in-place casting on advancing shoring, it was soon extended to self-launching gantry erection of precast segmental spans and span-by-span casting with movable scaffolding systems. Span-by-span assembly of simply-supported spans is the typical construction method for light-rail transit bridges with box girder and dual-track U-section. Large-scale highway projects combine span-by-span erection with in-place casting of wet joints to achieve full structural continuity, to diminish the number of bearings and expansion joints, and to control propagation of the geometry errors of short-line match casting. The eBook explores pros and cons of the four temporary static schemes for span-by-span construction of precast segmental bridges, the corresponding post-tensioning systems and locked-in stresses, the stiffness interactions with the erection gantry, and staged application of post-tensioning to avoid opening of the epoxy joints and the risk of brittle span failure at span release. Fully integrated within the Bridge Engineering eManuals © project, the eBook discusses span assembly on shoring falsework and the different means and methods to strand-jack into position segmental spans delivered on barges in marine operations. It introduces the different types of self-launching gantries for span-by-span erection and explores the span assembly operations common to all types of self-launching gantries. Specific monographs of the Bridge Engineering eManuals © project discuss the different types of self-launching gantries in greater detail. 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.
