Statistical Models Of I-15 Bridge C-846: Changes In Natural Frequencies Due To Temperature, Gilbert Nichols

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Structural Health monitoring is to determine the condition of a bridge based on instrument measurements. The C-846 Bridge in Salt Lake City has such instrumentation. The bridge is located in Salt Lake City at about 2100 South and Interstate 15. This bridge has two kinds of instruments on it: accelerometers and thermocouples. The accelerometers measure the vibrations of the bridge. The accelerometers have been recording data on the bridge since 2001. The thermocouples, which measure temperature, were added as part of this thesis in April 2016.

In light of recent research, damage may be detected from measuring the change in …

Developing A General Methodology For Evaluating Composite Action In Insulated Wall Panels, Jaiden Thomas Olsen

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Precast Concrete Sandwich Panel Walls (PCSPW’s) have been in use for over 60 years. They provide a very efficient building envelope for many buildings. Characteristic PCSPW’s comprise an outer and inner layer (or wythe) of concrete separated by an insulating material. To use all of the material as efficiently as possible, the layers are attached by connectors which penetrate through the insulating layer and are embedded in either concrete wythe. These connectors make it possible for both layers of the wall to work together when resisting loads. The connectors are made out of plastic, or FRP, to prevent heat transfer …

Design Of Logan City's Stormwater Conveyance System, Kade Jacob Beck

Undergraduate Honors Capstone Projects

This report summarizes 10th West Engineers' (10WE) storm water conveyance design for Logan City. The implementation of the design mitigates flood risk due to storm water discharge , helps improve local water quality, and uses infrastructure that would otherwise be abandoned. The system collects storm water discharged along 1000 West and transports the water to the holding pond located at approximately 2400 West 2200 North, Logan, Utah (see Figure 1).

Logan City is located in northern Utah's Cache County. As development and redevelopment occur, storm water runoff quantities will …

Design Of A Metadata Framework For The Environmental Models With An Example Hydrologic Application In Hydroshare, Mohamed M. Morsy, Jonathan L. Goodall, Anthony M. Castronova, Pabitra Dash, Venkatesh Merwade, Jeffrey M. Sadler, Mohammad Adnan Rajib, Jeffery S. Horsburgh, David G. Tarboton

Civil and Environmental Engineering Faculty Publications

Environmental modelers rely on a variety of computational models to make predictions, test hypotheses, and address specific problems related to environmental science and natural resource management. Scientists and engineers must devote significant effort to preparing these computational models. While significant attention has been devoted to sharing and reusing environmental data, less attention has been devoted to sharing and reusing environmental models. A first step toward increasing environmental model sharing and reuse is to define a general metadata framework for models that is flexible and, therefore, applicable across the wide variety of models used by environmental modelers. This paper proposes a …

Exercise - Choose A Manager To Learn Multi-Criteria Decision Analysis - University Of Colorado Boulder, Joseph Kasprzyk

All ECSTATIC Materials

A prompt for an in-class exercise, so that students can learn basic principles of multi-criteria decision analysis. The ideal place for this exercise is to have it before the formal lecture of multi-criteria decision analysis. The students will start to gain an intuitive understanding of how to transform preferences to scores, how to weight the metrics, and how to make a final decision.

Introduction To Water Resources Systems - University Of Colorado Boulder, Joseph Kasprzyk

All ECSTATIC Materials

This is the introductory lecture to a Water Resource Systems and Management class from Spring 2017 at the University of Colorado Boulder, by Joseph Kasprzyk. Learning goals include (i) defining integrated water resources management, (ii) identifying Colorado water management issues (ii) identifying how RiverWare simulation and optimization can be used to develop water plans (iii) use the HyMod model to perform rainfall-runoff modeling (iv) generating random parameter samples and understanding how parameter uncertainty affects model results.

Hydroshare Gis: Visualizing Spatial Data In The Cloud, Shawn Crawley, Daniel P. Ames, Zhiyu Li, David G. Tarboton

Civil and Environmental Engineering Faculty Publications

Cloud-based data management systems are more conducive to collaborative efforts when they are integrated with cloud-computing tools that interact with their stored data. HydroShare, a web based data management system for climate and water data, has implemented an Application Programming Interface and a web application platform deployed using Tethys Platform to encourage the development of apps that interact with its data. HydroShare GIS is the result of one such development effort to provide cloud-based visualization of spatial data stored in HydroShare. It functions by accessing the spatial metadata contained within the HydroShare resource data model and overlaying datasets as layers …
