| Abstract: |
The objective of this paper is to summarize current theory, design, and construction methods of concrete segmental girder bridges and to propose future research needs. First, the analytical theory will be overviewed, including concrete creep and shrinkage, bending strength with external tendons and unbounded tendons, web crack control, anchorage, etc. Then, the paper covers design methods regarding corrosion, including the use of Electrically Isolated Tendons (EIT) system, Fiber Reinforced Polymer (FRP) tendons and other corrosion protection techniques. In addition, internal redundance; the use of ultra-high-performance concrete (UHPC); and standardization for expediting the concrete segmental bridge design will be presented. The paper concludes with a discussion of research needs for future development of concrete segmental bridges. |
