HIGH-PERFORMANCE CONCRETE FOR BRIDGE 8F IN FREDERICA

The primary objective of this project was to gain an understanding of the actual post-construction performance of high performance concrete (HPC) bridge structures from both materials and structural behavior perspectives, based on the design and construction of Bridge 8F in Frederica, Delaware. The report is organized as follows: Chapter 1 provides an introduction. Chapter 2 describes HPC, presents its benefits, and discusses the relevant literature. Chapter 3 describes the experimental program, and the instrumentation used, as well as presenting details of Bridge 8F. Chapter 4 presents the material test results (compressive strength, elastic modulus, modulus of rupture, splitting tensile strength and shrinkage), their comparison to current code equations and structural response (temperature, corrosion, concrete strain and strand strain). Chapter 5 presents methods for predicting prestress losses. Chapter 6 presents a comparison of measured and calculated losses. Chapter 7 presents the conclusions of the research and recommendations for future work.
