There are three primary objective of the research project. The first is to validate analysis and design assumptions for simply supported girders, compatibility of deformation between girders and link-slab, force-deformation behavior and strain state in link-slab under prescribed end-rotations, and link-slab softening. The second objective is to investigate limit-states design methods (methods for assessing firder end rotations and allowable link-slab reinforcement strain for various load conditions) and simplified design procedures for link-slab bridges. Live load testing, long term live load testing, and seasonal thermal testing will all be done on the bridge. The final objective is to develop a guide for long-term monitoring.
