MPC Research Reports
Filter by University96 report(s) found for Colorado State University 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... This research focuses on finding a method for creating cost effective and innovative steel bridges in Colorado. The design method that was discovered to create this cost efficiency was designing the beams as simply supported for non-composite dead loads, beam weight and wet concrete, and then making... This research was undertaken to: 1) design and construct a wall and basic subassembly of an emergency storm shelter comprised entirely of wood that could resist a "missile" impact at 100 mph or multiple impacts at 80 mph; 2) study the difference in impact response for various specimen configurations... This research focuses on the beneficial utilization of Spray Dryer Ash (SDA) and investigates its performance in concrete for structural and transportation applications. Based on the challenges associated with disposal of all coal ashes, and SDA in particular, and the economic and environmental costs... |
