Filter by University94 report(s) found for Colorado State University Over the last two decades many researchers have focused on providing new ideas and frameworks that can help improve conventional bridge inspection practices; however, little guidance is provided for implementing these new ideas in practice. This, along with resistance to change and complexity of the... The recent rapid development of commercial unmanned aerial vehicles (UAVs) has made collecting images of bridge conditions trivial. Measuring a defect's extent, growth, and location from the collected large image set, however, can be cumbersome. This paper proposes a streamlined bridge inspection system... The objective of this study was to simulate the stress-displacement behavior of a flexible debris-flow mitigation structure with a three-dimensional finite element model (FEM). Flexible, steel ring-net structures are becoming state-of-practice for debris-flow mitigation in mountainous terrain. These... Cross Laminated Timber (CLT) has only recently garnered attention as a new construction material in the United States. Despite being introduced in Europe nearly 20 years ago, CLT is still not used widely in North America. One primarily reason is because CLT is not yet recognized as a structural system... On September 11-17, 2013, Colorado suffered devastating and widespread flash flooding over 150 miles from Colorado Springs north to Fort Collins, impacting 24 counties. The flood damaged several bridges and over 400 miles of state roads. As a result of the transportation damage, residents of Drake, Colorado... Hydrologic analyses are used for dam safety evaluations to determine the flow a dam must pass without failing. They are also used to evaluate bridge and culvert designs. Many current guidelines model flood runoff solely by an infiltration-excess mechanism. Saturation-excess runoff and subsurface stormflow... When designing transportation infrastructure, stormflow hydrographs are commonly estimated using synthetic unit hydrograph (UH) methods, particularly for ungauged basins. Current synthetic UHs either consider very limited aspects of basin geometry or require explicit representation of the basin flow... Due to the current limitations on seismic forecasting, there is a high chance that a considerable number of vehicles would remain on a bridge when an earthquake occurs. In traditional seismic analyses, traffic loads were often ignored. Existing mode-based bridge-traffic interaction analysis usually cannot... 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... |
