Principal Investigator:
Ohio Department of Transportation
Research Start Date:
Varies (earliest 1994)
Expected Completion Date:
Varies (latest 1998)
Research Objectives:
The objectives of these studies are to generate factual data about the actual ranges of state parameters and the loading environments for common bridge types; gain an understanding of how bridges actually respond to many different external and intrinsic loading effects and the mechanisms which trigger the actual (as opposed to envisioned) limit-states; establish the actual capacities of the different mechanisms which resist load effects at the serviceability and damageability levels; and establish the effects of aging and deterioration on both load demands and capacities.
Expected Products or Deliverables:
A database characterizing actual ranges of bridge state parameters; analytical and experimental tools together with use-modes and application rules for condition assessment and reliability evaluation; use-modes and application rules for field instrumentation and data acquisition; fully operational test-beds available for future research projects; and quantification and characterization of the effectiveness of a wide range of indices at detecting aging and deterioration.
