Filter by Keyword24 report(s) found with inspection in the keywords field The current legally required two-year inspection interval for most bridges is not an efficient system for conducting inspections, because many bridges do not require inspections this frequently, while others would benefit from more frequent monitoring. The research presented herein is based on the premise... National Bridge Inspection Standards do not require documenting damage location during an inspection but bridge evaluation provisions highlight the importance of location to determining the structural impact of damage. Capturing damage location information using current inspection and documentation methods... Ever since the introduction of the National Bridge Inspection Standards (NBIS) in 1971, there has been a tremendous amount of effort put into bridge rehabilitation programs and safety inspections. The Wyoming Department of Transportation (WYDOT) inspects these bridges in accordance with the NBIS on regular... Bridge inspection is an important phase in bridge management. In 2009, a joint American Society of Civil Engineers Structural Engineering Institute and AASHTO Ad-Hoc group was created to identify the issues in bridge safety and to study current bridge practices. This group recommended: "A more rational... This report presents a two-part research program examining the performance of constructed bridges in a cold region, represented by those in the State of North Dakota, and the behavior of concrete members strengthened with carbon fiber reinforced polymer (CFRP) composite sheets in such a service condition.... There are 16 small to medium simple span bridges in Larimer County that are currently load rated solely based on visual inspections. Most of these bridges are prestressed concrete bridges. The objective of this project is to load rate these bridges using structural analysis with very little to no information... This study aims at conducting the feasibility study on detecting damage of bridges through using passing vehicles and wireless sensors. As the first step, the finite element program has been compiled and some explorative tests have been conducted. It is found that the damage detection process is affected... While SafeStat was designed to prioritize carriers for monitoring and compliance reviews, the ISS was designed to prioritize carriers for roadside inspection. However, both algorithms use similar data to define a relatively unsafe carrier. It would be beneficial if there could be one uniform motor carrier... This project evaluated the opinions of commercial vehicle drivers and safety inspectors regarding the roadside inspection process and motor carrier safety. Surveys were developed in cooperation with the Office of Motor Carriers and used to question a representative sample from each of the groups nationwide.... The Inspection Selection System (ISS) was developed as part of the ASPEN roadside inspection software system, in response to a 1995 Congressional mandate calling for the use of prior carrier safety data to guide the selection of vehicles and drivers for roadside inspections. The ASPEN system includes... |
