Abstract

A In this paper, a new prestressed concrete girder system is presented which is designed using a detensionable and retensionable system. Experiments were carried out in order to comprehend the behavior of detensionable and retensionable prestressed concrete girder system. Tension control tests were performed for the detensionable and retensionable system followed by the static loading tests to check the applicability of the girder system. The test results were found in good agreement with the analytical results which clearly indicates the reliability of the concept of detensionable and retensionable prestress concrete girder with projected flange.
