A Novel Methodology for Quantifying the Performance of Constructed Bridges in Cold Regions
This report presents a two-part research program examining the performance of constructed bridges in a cold region, represented by those in the State of North Dakota, and the behavior of concrete members strengthened with carbon fiber reinforced polymer (CFRP) composite sheets in such a service condition. For the first phase, a total of 1,328 decks are sampled from a 15-year inspection period. These data are statistically characterized and probabilistically analyzed. The second part of the research concerns predictive investigations into the axial behavior of concrete exposed to aggressive service environments. Two types of concrete cylinders are studied: unconfined and confined with CFRP sheets. The aggressive environment and service traffic load are represented by freeze-wet-dry cycles with various levels of instantaneous compression load varying from 0% to 60% of the capacities of the unconfined and confined control concrete. Research approaches include three-dimensional deterministic finite element and probabilistic models, associated with a previously conducted experimental program. The effect of the instantaneous live load is significant on the performance of the unconfined and confined concrete, including the variation of compliance and volumetric characteristics.
