STATE OF THE ART EXTERNALLY POST-TENSIONED BRIDGES WITH DEVIATORS. INTERIM REPORT

This report is the first in a series outlining a major study of the behavior of post-tensioned concrete box girder bridges with post-tensioning tendons external to the concrete section. It presents an extensive literature review tracing the history and development of the technology connected with the use of external post-tensioning systems for bridges. Many of the references summarized have previously been available only in French or German language versions. The report summarizes the historical development of external post-tensioning, the advantages and disadvantages of external post-tensioning, and highlights the design and construction details for deviators. It presents the general basis for a detailed investigation of deviator design and briefly describes development of a complex testing rig for external tendon deviator tests.
