Composite behavior of precast bridge deck-panel systems

摘要

Experimental and analytical studies were conducted to investigate the composite behavior of precast concrete bridge deck-panel systems. A full-scale, single-span bridge was constructed. Fatigue tests and ultimate load test?, were conducted with different shear-connector types and various pocket spacing. Different construction details were compared for strength, fatigue performance, and ease of construction. Results of the research program were used to recommend the best construction details to use and propose design practices thai account for the variables that make precast concrete bridge deck-panel systems unique.
