Optimum Lifetime Planning Of Bridge Inspection And Repair Programs, Dan M. Frangopol, Allen C. Estes Aug 1999

Optimum Lifetime Planning Of Bridge Inspection And Repair Programs, Dan M. Frangopol, Allen C. Estes

Architectural Engineering

This study proposes a general methodology for determining the optimal lifetime planning of bridge inspection and repair programs based on minimizing the expected cost while maintaining an acceptable level of reliability. For individual bridges, this methodology determines the optimum inspection technique. and the numbers and timing of inspections and repairs. The methodology is demonstrated initially on a simple structure. Then. the method is applied to the optimial planning of inspection and repair programs for an existing bridge. The proposed approach to the problem of lifetime bridge maintenance is shown to be a viable method for optimizing inspection and repair investments …

Repair Optimization Of Highway Bridges Using System Reliability Approach, Allen C. Estes, Dan M. Frangopol

Architectural Engineering

As reliability based methods gain increased acceptance, there is greater opportunity to use scarce resources more efficiently while maintaining a prescribed level of reliability of a structure throughout its service life. The goal is to provide management decisions that will balance lifetime system reliability and expected life-cycle cost in an optimal manner. This study proposes a system reliability approach for optimizing the lifetime repair strategy for highway bridges. The approach is demonstrated using an existing Colorado State highway bridge. The bridge is modeled as a series-parallel combination of failure modes, and the reliability of the overall bridge system is computed …
