By the s, prestressed concrete largely superseded reinforced concrete bridges in the UK, with box girders being the dominant form. In short-span bridges of around 10 to 40 metres (30 to ft), prestressing is commonly employed in the form of precast pre-tensioned girders or planks.
1 Types of reinforced concrete bridges. The type of reinforced or prestressed concrete bridge deck depends mainly on the functional requirements, the structural form, and the main span length of the construction. Precast or cast in situ reinforced concrete (r.c.) bridge decks can be practically applied for all structural types, like arch, cable.
This technology is applicable and needed for both existing and new bridge construction. Over the past 50 years, thousands of short to medium span bridges have been built using precast concrete elements.
There are a large number of papers on the use of precast concrete. 65 REFERENCES 1. Reflections on the Beginnings of Prestressed Concrete in Amer- ica, Precast/Prestressed Concrete Institute, Chicago, IL () pp.

Five bridges designed in Europe of a segmental precast girder type were constructed between and Uses of Prestressed Concrete There are a huge number of uses: • Railway Sleepers; • Communications poles; • Pre-tensioned precast “hollowcore” slabs; • Pre-tensioned Precast Double T units - for very long spans (e.g., 16 m span for car parks); • Pre-tensioned precast inverted T beam for short-span bridges;File Size: 1MB.
Practice oriented papers and articles ON PRESTRESSED Load and Resistance Factors for Concrete Bridges and Buildings. Publication: Special Publication Date: 4/1/ Development of a New Short-Span Bridge System — A Comprehensive Approach. Prestressed concrete bridges were more and more built as segmental bridges, which mean the bridge is built in short sections or segments, either cast in situ or precast.
Cast In Situ Methods that are often used for cast in situ include the cast in situ posttensioned method, the balanced cantilever, and incrementally launched methods etc.English, Book, Illustrated edition: Precast prestressed concrete short span bridges: spans to feet.
Prestressed Concrete Institute (U.S.) Get this edition. Precast, prestressed concrete adjacent box girders are regularly considered for short- to medium-span bridges on secondary roads. This corresponds to spans from 20 ft to ft ( m to m. Precast Concrete - Precast Building System Solutions traditional reinforced concrete is the most economic method for a span of up to 6 m.
Prestressed concrete is more economical when spans are. As part of a project with the Iowa Department of Transportation to develop a set of standards for single span prefabricated bridges in the 30' - 70' span range for use by Iowa counties, HDR provided recommendations for a preferred system utilizing precast concrete voided concrete slab beams for the shorter span ranges and precast/prestressed concrete box beams for longer span ranges.

Precast prestressed concrete can be a strong, durable, and aesthetically pleasing material for use in long‐span bridges. If erected using the proper techniques and care, such bridges meet society's demands very well. Specifically, prestressed concrete allows for stronger bridges at lower construction and maintenance costs.
This paper investigates retrofitting precast, nonprestressed, channel beams (PCB) used in short-span bridges to improve beam shear strength and, consequently, beam ductility.
Three retrofit approaches were investigated: applying carbon-fiber-reinforced polymer (CFRP) strips, applying an epoxy spray-on, and retrofitting by installing shear bars.
A properly engineered prestressed-concrete beam can span longer distances than a reinforced-concrete beam and it is thinner, lighter in weight, and uses less concrete without cracking or breaking. Figure 1 - Here is Belgian engineer Gustave Magnel’s drawing that explains prestressing by showing how a row of books, pressed tightly together end.
A segmental bridge is a bridge built in short sections (called segments), i.e., one piece at a time, as opposed to traditional methods that build a bridge in very large sections. The bridge is made of concrete that is either cast-in-place (constructed fully in its final location) or precast concrete (built at another location and then transported to their final location for placement in the Ancestor: Box girder bridge.

Precast beams with an in situ concrete deck slab are popular for short- and medium-span bridges, especially where existing precasting facilities result in cost savings being achieved.
For spans up to 30 m precast beams compete favourably on cost terms. Both pretensioning and post-tensioning are included as well as precast and in situ construction. Recent developments in the use of non-metallic materials to improve the durability of prestressing systems and higher strength concrete are included to show how prestressed concrete bridges are likely to develop in the future.

Rajagopalan; Publisher: CRC Press ISBN: Category: Technology & Engineering Page: View: DOWNLOAD NOW» Simple design, low life cycle costs, and fast, easy construction are just a few of the reasons that make prestressed concrete attractive for use in bridges, water and wastewater storage tanks, ocean dock construction, flooring, and more.
It was the consensus of bridge designers and producers alike that the publication, Precast/Prestressed Concrete Short Span Bridges - Spans to Feet and the Design Supplement to Short Span Bridges had served their original purposes.

Self-launching gantries and lifting frames are used to erect precast segmental bridges. Movable scaffolding systems (MSS) and form travellers are used for in-place casting of spans and segments of prestressed-concrete bridges.
Forming carriages are used for segmental casting of the concrete slab of composite bridges. Post-tensioned concrete is used for cast-in-place concrete and for bridges, large girders, floor slabs, shells, roofs, and pavements.
Principles of Prestressed Concrete. In concrete, a large prestressing force is applied by tendons embedded into it to develop high. Whether you want to replace a deficient structure, span a roadway or water, or create a tunnel, precast concrete bridge components provide the perfect solution.
Designs include attractive single-piece arches, functional two-piece arches, conventionally reinforced flat. construction to lightly traveled short span bridges using prestressed hollow core sections.
However, in some areas of the US such as the Pacific Northwest, longer span bridges are being built from prestressed deck bulb tee girders with reinforced decks cast integrally with the girder. N2 - This paper describes a field investigation of a Precast Composite Slab Span System (PCSSS) implemented for short to moderate span bridges (ft.
range). Advantages of the system include accelerated construction, improved quality control, and reduced impact on the environment compared to cast-in-place (CIP) slab span : Catherine E. French, Carol K. Shield, Matthew Smith, Whitney Eriksson, Dave Klaseus. For years, adjacent prestressed concrete box-beam bridges have been employed for short and medium spans—two-thirds of all state Department of Transportations (DOTs) use them.
Cracks in the longitudinal grouted joints between adjacent beams have often been observed. (A) Precast, Prestressed Concrete Girders. Bridge Construction. Post-Tensioning of Girders.
