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 …

A Quantitative Method For Estimating Probable Public Costs Of Hurricanes, Michael R. Boswell, Robert E. Deyle, Richard A. Smith, E. Jay Baker

City and Regional Planning

A method is presented for estimating probable public costs resulting from damage caused by hurricanes, measured as local government expenditures approved for reimbursement under the Stafford Act Section 406 Public Assistance Program. The method employs a multivariate model developed through multiple regression analysis of an array of independent variables that measure meteorological, socioeconomic, and physical conditions related to the landfall of hurricanes within a local government jurisdiction. From the regression analysis we chose a log–log (base 10) model that explains 74% of the variance in the expenditure data using population and wind speed as predictors. We illustrate application of the …

A Model To Minimize Non-Revenue Costs In Bus Transit Operations, Cornelius Nuworsoo

City and Regional Planning

This paper derives from feasibility studies for a proposed Bus Division of the Mass Transit Administration (MTA) to serve northeastern Baltimore. The study objective was to determine the comparative savings or additional costs between using existing versus new locations. The focus of the analysis was non-revenue operating costs which are affected by location because of vehicle deadhead travel, associated operator travel and other operator travel for relief purposes.

Based on the premise that “the optimal location of a storage facility is that which minimizes pullout and pull-in distances and times plus relief travel time between the facility and various …
