Research Reports
View AllThe 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... The objective of this report is to provide a benchmark for elevator managers in assessing performance, and supply a source for recognizing trends in the characteristics of North Dakota elevators. This report and the statistics mailed to individual elevators are presented as a source of information for... This study investigates the nexus of transit and rural livability by conducting case studies in the North Dakota communities of Valley City and Dickinson. While many factors influence the livability of a rural community, transit is an important contributor. For each of the two North Dakota communities...

In this report, infrastructure needs are estimated using the most current production forecasts, traffic estimates, and roadway inventory... This report represents a continuation of analysis concerned with the patterns and methods of distributing grains and oilseeds from North Dakota. This series began with the analysis of 1956-57 data and was published in Agricultural Economics Reports 15, 17, 44, 56, and 86 and Agricultural Experiment Station... Most roads in the City of Madison, South Dakota were built more than 30 years ago, with chip seal as the primary maintenance practice. However, such treatments only provide temporary solutions to the surface and do not improve the structural deficiencies. To prevent accelerated pavement deterioration... This Fact Book provides information on transit service availability and cost to help the transit industry in the United States provide efficient and effective service to meet rural community mobility needs. Financial and operating statistics can be used by agency managers, local decision makers, state... 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... For highways located in different counties and cities across the country, specific conditions of weather, terrain, traffic characteristics, highway conditions, population and economic development are all different. Driving environments, traffic accidents and injury risks have strong interactions, which... Hyperspectral remote sensing is an emerging field with many potential applications in the observation, management, and maintenance of the global transportation infrastructure. This report describes the development of an affordable framework to capture hyperspectral images and models to classify the images.... |
