PRESTRESS LOSSES OF IN-SERVICE HIGHWAY BRIDGE MEMBERS - A LITERATURE SURVEY

The report presents a survey of literature concerning the prestress loss characteristics of in-service bridge members in comparison with those of laboratory specimens. In Chapters 2, 3, and 4 respectively, findings by previous researchers related to camber and deflection, shrinkage and creep, and prestress losses are presented and discussed. Chapter 5 provides a brief summary, and shows the need for further research. The work was done as part of a research project entitled 'Evaluation of Prestress Loss Characteristics of In-Service Bridge Beams.' This project is aimed at establishing a comparison between the behavior of laboratory specimens and that of in-service structural members, and to formulate necessary adjustments to a previously developed procedure for estimating prestress losses in pretensioned bridge members.
