Abstract:

A recently completed study suggests that approximately 25% of them are either structurally deficient or functionally obsolete (FHWA, 2007). Therefore, the Federal Highway Administration (FHWA) and the Oklahoma Transportation Center (OTC) have made it a priority to seek new methods to economically and effectively inspect and monitor bridges. In response to this need, structural health monitoring (SHM) has been developed for bridge inspection and monitoring. However, implementation of SHM on bridges is not common because of the following challenges: (1) difficulties in integration of the information from sensor networks, (2) economic justification of SHM for the structure, and (3) the lack of a standard procedure for owners and inspectors to follow for SHM of bridges. To address these challenges, the overall objective for this project is to produce some guides for owners and design engineers to inform and assist them in deciding when SHM is useful. The following research tasks are reported in this document: (1) Conduct case studies of bridge inspection using SHM systems based on previous sensor networks used by the industrial partner and provide suggestions for hybrid sensor networks, (2) Develop a guideline for using analysis techniques (e.g., finite element analysis) as a screening tool to determine the most critical areas of the structural system, (3) Establish methods for determining types/numbers/locations of sensors to be used to study the performance of the structure, and (4) Create tools using statistical analysis and signal processing for analyzing the data from the SHM system when making repair decisions.
