Inspections have found that the precast concrete deck, on one of a pair of bridges, appears to be performing better than the cast-in-place concrete deck on the twin bridge. A wider spacing than 24 in. for the composite connections between precast concrete deck panels and bridge girders appears Size: KB.
Structural Tests of Precast, Prestressed Concrete Deck Panels for California Freeway Bridges. This paper describes full-scale structural tests of 5 precast, prestressed concrete bridge deck panels conducted in simple bending to failure at the San Diego State University Structural Engineering Laboratory, San Diego, California. of precast concrete to bridge structures are the connection elements. Connection details include the use of post-tensioning systems, and various connection details such as weld plates, studs in grout pockets, and shear keys. The Minnesota Department of Transportation (Mn/DOT) constructed a bridge incorporating precast elements to enable.
Abstract. In this paper, a connection between precast beam and precast slabl to be used in decks of precast composite bridges is studied. The difference between this connection and the common connection used in bridge construction is that in this paper the steel connector is associated with a shear-key which is formed on the top face of the precast beam, and a high, performance concrete Cited by: 4. 1.

Precast and prestressed concrete composite bridge deck panels are used with cast-in-place concrete to provide a convenient and cost effective method of construction for concrete bridge decks. The panels are usually precast at a manufacturing plant.
They are trucked to the bridge construction site and lifted by cranes onto concrete or steel girders. Bridge Decks, Precast Concrete, Composite Bridges, Epoxy Mortar, Shear Connectors, Structural Models, Static Load Test Distribution Statement No restrictions.
This document is available to the public through the National Technical Information Service Port Royal Road Springfield, Virginia Security Claud. The objectives are to report the results of a repetitive load test conducted on a scaled model of a precast-decked, simple span bridge; to describe the performance of the model during a repetitive load test; and to discuss the adequacy of existing fatigue design criteria for shear connectors embedded in epoxy Size: 4MB.
The proposed bridge can reduce the negative moment of the girder through continuous connection. In this study, a full-scale connection specimen with a m span was fabricated, and the behavior of the precast connection was evaluated by performing a negative moment performance : Heeyoung Lee, Heeyoung Lee, Junki Min, Wonseok Chung.
Experimental test results indicate that closely-spaced studs in the shear pockets in the precast deck panels provide adequate composite action in composite bridge girder design.
In steel stringer bridges the most common type of shear transfer device is shear studs welded to the top flange of the stringer. Once the shear studs are welded, the concrete slab is cast; however, precast concrete panels may also be used.
In the latter, cast holes in the panels accept the shear 00nnectors. Precast concrete floors comprise precast floor units topped with in-situ (often lightly) reinforced concrete topping to form a composite floor system that generally also functions as a diaphragm.

Results are presented for an experimental program conducted on a 10 m span full-scale lightweight concrete slab-steel beam composite bridge deck unit. Loading history included 10 million cycles of flexural fatigue loading, followed by a flexural load capacity : Richard N.
White. In this paper, experimental and analytical studies of two-span continuous composite bridges with open box girder section were conducted. Cracking, yielding and ultimate loads were evaluated and compared with the test results for design of continuous composite bridges with precast by: 3.
The project consists of twin two-span bridges: a south bound bridge with cast-in-place concrete deck; and north bound bridge with precast concrete deck. Construction of the superstructure (girders, deck, and rail) of the two bridges was done concurrently starting in May and was completed in September of Author: George Morcous, Fouad Jaber, Jason Volz.
The modern trends in the development and application of precast concrete bridges are discussed. The development of precast bridges has been mainly done by the precast industry in collaboration with public authorities.
Initially, the projects were based on. Prestressed concrete decks are commonly used for bridges with spans between 25m and m and provide economic, durable and aesthetic solutions in most situations where bridges are needed.
Concrete remains the most common material for bridge construction around the world, and prestressed concrete is frequently the material of choice. Extensively illustrated /5(4). Lam et al., looked into the behavior of composite floors made of steel beams and precast concrete hollow core slabs and proposed the design recommendations.

Depth Precast Concrete Bridge Deck Panels” . This report will be published by the Precast / Prestressed Concrete Institute (PCI) later this year. INTRODUCTION. Some regulatory authorities are willing to pay a premium to minimize interference with traffic during construction.
Traffic holdups also have an adverse impact on the environment. Precast Concrete Structures introduces the conceptual design ideas for the prefabrication of concrete structures and presents a number of worked examples of designs to Eurocode EC2, before going into the detail of the design, manufacture, and construction of precast concrete multi-storey buildings.
Analysis predicts that positive restraint moments do not develop for all precast girders made continuous. Analysis also predicts that precast girder bridges with composite deck slabs that are made continuous will develop negative restraint moments because of differential shrinkage between the girders and the deck.
Part 2: Test Protocols and Case Studies. As discussed in Load Testing of Concrete Structures – Part 1 (STRUCTURE ® magazine, April ), load testing can be used to determine the ability of a structure to carry additional loads, to establish the safety of structures, to validate strengthening, to gain knowledge on the behavior of a structure, and to .The theory is supported by numerous worked examples to Eurocodes and European Product Standards for precast reinforced and prestressed concrete elements, composite construction, joints and connections and frame stability, together with extensive specifications for precast concrete structures.
