MPC Research Reports
Filter by University109 report(s) found for Colorado State University The motivation for this report is a proposed new microelectromechanical systems (MEMS) sensor with applications in civil infrastructure sensing. This report analyzed the influence of three assumptions employed in the Euler-Bernoulli, Rayleigh, and Timoshenko beam theories by comparing their results to... Depending on the location, highway bridges can often support considerable amounts of traffic. Due to the limitations on current earthquake forecasting techniques, a normal amount of traffic will also typically remain on a bridge when an earthquake occurs. In addition to traffic, scour effects are also... Over the years, Fiber Reinforced Polymer (FRP) composites have gained popularity in transportation infrastructure as a material able to restore and increase the capacity of existing concrete elements. Properties such as a high strength to weight ratio, non-corrosive nature, durability, and high malleability... This report describes research performed in coordination with work at the University of Stuttgart, attempting to establish the S-N curve for fatigue loading of notched wood-concrete connections based on low/high-cycle, repeated loading tests. Experimental results are obtained on fourteen 1524 mm span... Alternatives to existing transportation truck escape ramps and crash barriers are examined using arrays of wood, bamboo, and fiberglass structural elements that act as energy absorbers as they deform. The behaviors of each material type are analyzed to determine if they have the necessary potential for... This report details the outcomes of shear spiking two open-deck, timber trestle railroad bridges and examining the effectiveness under applied loading. The bridges were made available to the researchers by the Union Pacific Railroad and were located in their Southern Region. The first site was located... An attempt is made to integrally evaluate the safety of large trucks on mountainous highways. The I-70 corridor in Colorado is chosen to demonstrate the methodology because of its typical mountainous terrain and adverse weather conditions. First, the ten-year historical accident records are analyzed... The objective of this research is to investigate the injury severity of truck drivers by studying MV and SV accidents involving trucks on rural highways separately. By using multinomial logit models, the complex interactions between roadway characteristics, driver characteristics, accident characteristics... 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... The use of off-specification fly ashes to increase the shear strength and stiffness of an expansive soil-rubber (ESR) mixture is investigated systematically in this study. The off-specification fly ashes used include a high-sulfur content and a high-carbon content fly ash. A class C fly ash is used as... |
