Filter by University96 report(s) found for Colorado State University Long-span bridges support a large amount of traffic every day. Even when an earthquake strikes, a long-span bridge often still has many vehicles present due to the low predictability of earthquake events. To study the seismic performance of bridge and traffic systems, a new full-response prediction methodology... In order to predict the functionality of transportation networks following a seismic event, performance of embankments under real ground motions needs to be well understood. Understanding of such performance can be realized using experimental testing or finite element analysis. This study aims to add... Mitigating traffic congestion and reducing transportation emissions are among the leading goals of most local, regional, national, and international agencies. Several guidelines rely primarily on strategies that support the following: 1) mixed land-use and transit-oriented developments, 2) multimodal... Millions of cubic yards of concrete and steel used to support the U.S infrastructure may result in a significant negative impact on the environment. CO2 released by construction processes, as well as material production, is taking a substantial toll on the environment. This study seeks to develop a system... Steel bridges with reinforced concrete substructures and steel superstructures are considered to have superior performance under earthquakes when compared with their reinforced concrete counterpart. Such performance reputation stems from the fact that few steel bridges have been subjected to strong ground... Bridge expansion joints are a particularly troublesome component of bridges and many departments of transportation (DOTs) are looking for a solution to deteriorating expansion joints on highway bridges. Bridge expansion joints create a break in the structural continuity of a bridge, allowing clogging... The use of Carbon Fiber Reinforced Polymers (CFRP) for the repair of civil infrastructure has been on the rise. Most studies have focused on the effect of CFRP to increase the stiffness and strength of reinforced concrete beams or columns. Limited attention has been given to the effect of CFRP on mitigating... Of all microelectromechanical systems (MEMS), regardless of application, micron-scale spacing of interleaved electrodes and high-dielectric ceramics in multilayer ceramic capacitors (MLCCs) provide exceptionally high capacitances in small volumes. This has led to MLCCs being the preferred type of capacitor... 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... Ductile fracture has been identified as the predominant mode of failure for structural elements under extreme loads and the prediction of such represents considerable challenges. Until recently, ductile fracture of metals has been recognized to be dependent on both stress triaxiality and Lode angle parameter.... |
