Research Reports Filter by Keyword91 report(s) found with bridges in the keywords field This effort responds to a North Dakota League of Cities request for a study of the transportation needs of the largest 14 urban centers in the state. The study was funded by the North Dakota League of Cities and the North Dakota Department of Transportation. The North Dakota League of Cities, along with... The objective of this project is to find effective configurations for using buckling restrained braces (BRBs) in both skewed and curved bridges for reducing the effects of strong earthquakes. Verification is performed by numerical simulation using analytical models of existing bridges when BRBs are implemented...

In this report, infrastructure needs are estimated using the most current production forecasts, traffic estimates, and roadway inventory... Reinforced concrete (RC) bridges with both skew and curvature are common in areas with complex terrains. Skewed and/or curved bridges were found in existing studies to exhibit more complicated seismic performance than straight bridges, however the related seismic risk studies are still rare. These bridges... 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... The long-term objectives of this project were to develop and validate an instrumentation package for structural health monitoring of bridges subjected to overweight trucks and to develop plans for field deployment of the instrumentation on a pilot scale. Ultimately, the objective is to accurately correlate... This report evaluates two new glass-fiber reinforced polymer concrete reinforcement systems, which have been designed to serve as a non-corrosive alternative to steel reinforcement in reinforced concrete bridge girders. Due to the nature of the reinforcement geometry, these systems react in a way to... Simple-made-continuous (SMC) steel bridges are a relatively new innovation in steel bridge design. The SMC concept is a viable solution for steel bridges to recover market share of the bridges constructed in the United States. The majority of SMC bridges currently in use are constructed with concrete... This paper presents the results of an experimental study on the fatigue performance of RC beams strengthened with different externally bonded CFRP systems. Seven specimens were fabricated; three had no CFRP; the remaining four had one of two CFRP systems. The objective of this study was to determine... This report presents a research examining the feasibility of creating an integrated structural health monitoring and impact/collision detection system for bridges in remote cold regions, where in-person inspection becomes formidable. The research report includes a theoretical analysis of the impact event...
