Synthesis of National and International Methodologies Used for Bridge Health Indices

Wednesday, June 22, 2016 - 18:00

Bridge performance measures are important components of any successful Bridge Management System. Different types of performance measures have been developed for various purposes. The types of performance measures are usually a reflection of an agency’s goals. The bridge health or condition index is a type of performance measure used by agencies interested in preserving the condition of bridge structures. Bridge condition index is very attractive because it provides a single index for assessment of the structural and or functional health of a bridge based on the condition of the bridge’s structural elements and the services provided by the bridge. As outlined in the FHWA’s Long-Term Bridge Performance Program, the development of condition indices should be driven by more objective and quantitative data to help bridge managers make informed decisions. This work reviews the state-of-the-art with respect to bridge condition indices being used to assess performance of bridges in the United States and other countries.
