Record URL: Availability: Transportation Research Board Business Office 500 Fifth Street, NW Find a library where document is available Abstract: Innovative methods are presented for using precast concrete members in bridge construction; summaries include the essentials of design, detailing, and construction of precast, pretensioned girders; posttensioned spliced girders; and precast deck panels used for bridge structures. The key aspects of using precast members in seismic regions are discussed, with an emphasis on suitable connections that meet ductility requirements. Precast bridges consisting of pretensioned girders, posttensioned spliced girders, trapezoidal open-box girders, and other types of superstructure members have been gaining popularity in recent years. These types of bridges have the advantages of minimizing traffic disruption, accelerating construction, and solving constructability issues in traffic-congested areas and in other specific cases. Handling and shipping limitations often control the span capability of pretensioned girders. Spliced girder design has provided a solution where a one-piece pretensioned girder could not otherwise have been used. Precast deck systems consisting of precast, prestressed concrete deck panels have advantages in accelerated bridge construction and rapid deck replacement. A parametric study has been performed to demonstrate the effectiveness of using precast members in bridge structures. Design examples for each application that use load and resistance factor design specifications are provided. Criteria used in optimizing and developing standard drawings for precast bridge members are discussed. Recommendations for effective use of precast members in seismic regions are provided, and areas for further research are identified.
