Segmental Concrete Bridge Construction
Most Modern Bridges are Built Segmentally. In such bridges, the components carry loading in a configuration other than thecompleted structure. Stress during construction exceeds that of the completed structure. Early-age loading of concrete results in large deformations. Bridge engineers must keep these aspects in mind while designing segmental bridges. Major design objectives are:
- Geometry Control During Construction (Deflection and Camber)
- Crack Control During Construction (Stress Check)
- Structural Safety and Stability During Construction
- Control of Stresses in Completed Structure
- Control of Strength of Completed Structure
