Available in PDF, EPUB and Kindle. Book excerpt: Traditionally, prestressed concrete girder bridges are limited to 150 ft span lengths in Texas due to restrictions on handling and transportation. An effective way of increasing span lengths of precast, prestressed concrete girder bridges is demonstrated using splicing technique. In spliced girder bridges, precast girder segments are transported in shorter segments for handling and transportation and then spliced together to form long-span continuous bridges. Different methods are explored for construction of spliced girder bridges. Two application examples are developed to demonstrate the design of continuous prestressed concrete spliced girder bridges for both shored and partially shored methods of construction. A three-span bridge having a span configuration of 190-240-190 ft is considered for both examples. Advantages and disadvantages of each method of construction are discussed. Construction issues that should be considered in the design are highlighted. The results of this study indicate that span lengths up to 240 ft are achievable using standard Tx70 girders with the help of splicing techniques. A parametric study is performed to further explore the design space of spliced girder bridges. The results of the parametric study, along with critical design issues that were identified, are highlighted and related recommendations are provided. The results of this study will be of significant interest to bridge engineers and researchers for guidance in implementing spliced girder bridges in Texas and other states.

Available in PDF, EPUB and Kindle. Book excerpt: The Texas Department of Transportation designs typical highway bridge structures as simple span systems using standard precast, pretensioned girders. Spans are limited to about 150 ft due to weight and length restrictions on transporting the precast girder units from the prestressing plant to the bridge site. Such bridge construction, while economical from an initial cost point of view, may become somewhat limiting when longer spans are needed. This project focused on developing additional economical design alternatives for longer span bridges with main spans ranging from 150-300 ft, using continuous precast, prestressed concrete bridge structures with in-span splices. Phase 1 of this study focused on evaluating the current state-of-the-art and practice relevant to continuous precast concrete girder bridges and recommending suitable continuity connections for typical Texas bridge girders; the findings are documented in the Volume 1 project report. This report summarizes Phase 2 of the research including detailed design examples for shored and partially shored construction, results of a parametric design study, and results of an experimental program that tested a full-scale girder containing three splice connections. The parametric design study indicated that for bridges spanning from 150-300 ft, continuous precast, prestressed concrete girder bridges with in-span splices can provide an economical alternative to steel girder bridges and segmental concrete box girder construction. The tested splice connections performed well under service level loads. However, the lack of continuity of the pretensioning through the splice connection region had a significant impact on the behavior at higher loads approaching ultimate conditions. Improved connection behavior at ultimate conditions is expected through enhanced connection details. Recommendations for design of continuous spliced precast girders, along with several detailing suggestions are discussed in the report.

This book was released on 1974 with total page 175 pages. Available in PDF, EPUB and Kindle. Book excerpt: A Computer program has been developed in this study to perform the calculations for the design of continuous prestressed concrete bridge girders. The continuous girder is constructed from simple span precast concrete I-shaped beams made continuous by supplementary reinforcing in the deck and the ends of the precast beams. Specifications for the designs produced are those currently accepted by the State Department of Highways and Public Transportation. This volume of the report contains a description of the computer program, instructions for its use and information on its structure and operation.

This book was released on 1989 with total page 108 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report documents and presents results of a study to determine time-dependent behavior and relevant design criteria for simple-span precast, prestressed bridge girders made continuous. A questionnaire was used to determine current practice. Creep and shrinkage tests of steam-cured concrete loaded at an early age were made. Computer simulations were used to investigate the effects of time-dependent material behavior and variation in design parameters on the effective continuity for live load plus impact. The findings suggest that positive moment connections in the diaphragms at the piers are not required and provide no structural advantages. The findings also suggest that effective continuity for live load plus impact can vary from 0 to 100% dependent on the design parameters and timing of construction. Computer analyses were also used to determine an upper limit for the amount of negative moment reinforcement over the supports to insure full moment redistribution and attainment of maximum bridge strength. New computer programs were developed for simplified analysis to determine time-dependent effects and service moments. Recommendations for design procedures were presented and design examples given.

This book was released on 1979 with total page 280 pages. Available in PDF, EPUB and Kindle. Book excerpt: Tests of two prestressed concrete composite bridge girders which were continuous over two spans are reported. Both were I-section girders with cast-in-place decks, and had spans of about 37 ft (11 m), and were approximately 1/3 scale models of structures spanning 125 ft (38 m). Each girder was constructed from three segments which were joined end-to-end by cast-in-place concrete splices. Modell was post-tensioned after erection of the girders and casting of the deck and splice concrete. The two end segments, each supported on the final abutments and on temporary supports located about 1/3 of the span from the central pier, were pretensioned for their dead loads plus the deck concrete. The central segment, which was supported on the central pier of the structure plus the two temporary supports was precast reinforced concrete, plus a small amount of pre= tensioned reinforcement. Model 2 was externally similar, but was not post-tensioned. The segments were pretensioned for the final moments, and were joined by splicing reinforcing bars which extended into the splice region. Both structures were subjected to a series of loadings to the service load, design ultimate, and high over-load levels. Both had capacities which were significantly higher than the design ultimate values. The capacities were generally predictable on the basis of flexural strength calculations, and shear did not cause major problems. Joint details in Modell lead to difficulties in two tests, and this aspect of the design is discussed in detail.
