Continuous highway bridges with precast, prestressed girders have been built by a number of states. Examples of bridges of this type built by the states of Tennessee and California are presented in Figs.

1 and 2, respectively. The Big Sandy River Bridges in Tennessee were built in Performance has been excellent. The ft. and ft. AUTOMATED DESIGN OF CONTINUOUS BRIDGES WITH PRECAST PRESTRESSED CONCRETE BEAMS.

VOLUME 2: PROGRAM DOCUMENTATION. A Computer program has been developed in this study to perform the calculations for the design of continuous prestressed concrete bridge girders. Horizontally curved bridges made from precast concrete beams are com-petitive with steel girder bridges and cast-in-place concrete bridges.

The amount of competitive edge will vary with local project and market condi-tions. ANALYSIS AND DESIGN Design of the curved precast beams addresses flexure, shear, torsion, distor. assistant director: standards & design one gateway plaza, 12th floor, l.

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 throughout, this invaluable book /5(4). G.L. Balázs, T. Kovács, in Innovative Bridge Design Handbook, 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. Home / Precast Products / Bridges 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 bridges, parapets, wingwalls, headwalls and.

Aiding designers of concrete bridges in developing an intuitive understanding of structural action, this book thereby encourages innovation and the development of engineering architecture. Simple, relevant calculation techniques that should precede any detailed analysis are summarized.

These standard designs led to cost efficiencies both in design time and also the use of standard moulds by precasters led to more competitive tenders for supply of bridge beams.

This comprehensive document includes detailed design information on the full suite of Prestressed Concrete Bridge Beams available on the market today, including the Banagher Precast Concrete developed W-Beam and MY-Beam range.

Prestressed Concrete Bridges, Second edition, is the comprehensive reference for practising bridge engineers on the design and construction of prestressed concrete bridges.

Offering complete coverage of the design and construction of prestressed concrete bridges in a single resource, this book is an essential aid for maximising your efficiency.

The challenge is how to modernize these bridges efficiently and minimize the construction time needed to complete and return the bridge to service. Precast concrete bridge components are the answer.

Precast/prestressed bridge components cut construction time in half because bridge components are delivered to the job site ready to install.
