Determining the Uncertainty in the Current Condition of Bridges for Use in Risk Based Inspection and Management

The goal of this project is provide descriptions of uncertainty in structural condition that can be used to improve the timing of bridge inspections and bridge management practice in a risk or performance based framework. In order to achieve this goal, this project will pursue the following objectives: (1) identify all significant sources of uncertainty that are present in our knowledge of an existing bridge and affect understanding of bridge condition and performance; (2) quantify the effect of these sources individually using literature review and parametric studies; (3) investigate ways to combine the various sources of uncertainty into an overall level of uncertainty for a given structure; and (4) provide a simple demonstration of how this definition of uncertainty in bridge condition can be implemented in a framework for risk and performance based inspection planning. Attempting to achieve objectives 2 - 4 for all bridge types would imply a very large project scope, thus based on the quantity and quality of information that can be collected for different types of bridges, a narrow range of structural types will be selected for detailed study. At this point the project anticipates selecting slab and girder bridges with RC deck slabs and steel, reinforced concrete (RC) or precast girders.
