In-Plane Loading Of Brick Veneer Over Wood Shear Walls, Elias Anis Toubia, James M. Lintz 2016 University of Dayton

In-Plane Loading Of Brick Veneer Over Wood Shear Walls, Elias Anis Toubia, James M. Lintz

Elias Toubia

In the design of wood stud walls with brick veneer, current design building codes specify that the wood stud wall should resist all in-plane and out-of-plane loads (IBC 2009). For out-of-plane loads, this assumption is entirely justified as the brittle brick veneer will crack and lose its capacity to resist bending. For in-plane loads, the brick veneer is significantly stiffer than the wood shear wall, and the veneer is unlikely to crack before the wood shear wall reaches its allowable capacity. The assumption that the wood shear wall resists the entire load is based on the further assumption that the ...


Development Of Design Loads For Transmission Line Structures Subjected To Downbursts Using Aero-Elastic Testing And Numerical Modeling, Amal Elawady 2016 The University of Western Ontario

Development Of Design Loads For Transmission Line Structures Subjected To Downbursts Using Aero-Elastic Testing And Numerical Modeling, Amal Elawady

Electronic Thesis and Dissertation Repository

The failure of transmission line structures due to severe High Intensity Wind (HIW) events is one of the major problems facing the electrical utility companies in various places around the globe including Canada. An extensive research program focusing on this problem started about fifteen years ago at The University of Western Ontario (UWO). In this Thesis, two major milestones are achieved leading to the advancement of the knowledge in this field. The first milestone is conducting, for the first time, a test on an aero-elastic model of a multi-span transmission system under reduced–scale simulated downbursts. The first objective of ...

Development Of Railroad Highway Grade Crossing Consolidation Rating Formula, Zachary Hans, Christopher Albrecht, Patrick Michael Johnson, Inya Nlenanya 2016 Iowa State University

Development Of Railroad Highway Grade Crossing Consolidation Rating Formula, Zachary Hans, Christopher Albrecht, Patrick Michael Johnson, Inya Nlenanya

Michael Johnson

The goal of this project was to provide an objective methodology to support public agencies and railroads in making decisions related to consolidation of at-grade rail-highway crossings. The project team developed a weighted-index method and accompanying Microsoft Excel spreadsheet based tool to help evaluate and prioritize all public highway-rail grade crossings systematically from a possible consolidation impact perspective. Factors identified by stakeholders as critical were traffic volume, heavy-truck traffic volume, proximity to emergency medical services, proximity to schools, road system, and out-of-distance travel. Given the inherent differences between urban and rural locations, factors were considered, and weighted, differently, based on ...

An Investigation Of Railroad-Highway Grade Crossing Consolidation Rating In Iowa, Patrick Michael Johnson 2016 Iowa State University

An Investigation Of Railroad-Highway Grade Crossing Consolidation Rating In Iowa, Patrick Michael Johnson

Michael Johnson

Railroad-highway grade crossings present unique safety and operational challenges on both the rail and highway side. Consolidation of these crossings can be a valuable tool to improve safety, but is often a source of disagreement among interested parties. In order to better evaluate crossings to determine their suitability to be consolidated, a spreadsheet-based tool was developed to rank all public, at-grade crossings in Iowa using a number of factors related to potential consolidation impacts. The spreadsheet will act as a tool to provide an objective rating of each crossing for use in analysis and negotiation for crossing consolidation. This thesis ...

Automating Data Management And Sharing Within A Large-Scale, Heterogeneous Sensor Network, Jeffery S. Horsburgh, Amber Spackman Jones, Stephanie Reeder 2016 Utah State University

Automating Data Management And Sharing Within A Large-Scale, Heterogeneous Sensor Network, Jeffery S. Horsburgh, Amber Spackman Jones, Stephanie Reeder

Amber Jones

Hydrology researchers are collecting data using in situ sensors at high frequencies, for extended durations, and with spatial distributions that require infrastructure for data storage, management, and sharing. Managing streaming sensor data is challenging, especially in large networks with large numbers of sites and sensors. The availability and utility of these data in addressing scientific questions related to water availability, water quality, and natural disasters relies on effective cyberinfrastructure that facilitates transformation of raw sensor data into usable data product. It also depends on the ability of researchers to share and access the data in usable formats. In this paper ...

Time Series Analyst: Interactive Online Visualization Of Standards Based Environmental Time Series Data, Jeffery S. Horsburgh, Amber Spackman Jones, Maurier Ramírez, Juan Caraballo

Amber Jones

Visualization is a common need of many researchers, organizations, and projects that collect and use environmental sensor data. Web-based tools can provide screening-level visualization and data analysis functionality for users with a range of technical expertise. However, it is difficult to integrate data from multiple sources due to syntactic and semantic differences in data formats and different data delivery mechanisms that are not always interoperable. We developed an open-source time series visualization tool called the Time Series Analyst (TSA) that integrates data from multiple sources using web service interfaces and a standardized data encoding format. The TSA provides multiple types ...


Impedance-Based Water-Quality Monitoring Using The Parallel-Plate Method, Ali Nazari, Arvin Farid, Ken Cornell 2016 Boise State University

Impedance-Based Water-Quality Monitoring Using The Parallel-Plate Method, Ali Nazari, Arvin Farid, Ken Cornell

Arvin Farid

The application of electromagnetic (EM) waves to measure the electrical properties (dielectric constant and loss tangent) of materials is a well-known approach. The electrical properties can be used to indirectly measure several physical properties of solutions in water such as the concentration and chemical composition of contaminants in water, as a representative of the liquid phase in soil. A capacitive method of measuring dielectric properties of solutions is proposed to detect and determine low-concentration chemical and biological contaminations in water. The primary objective of this project is to design a low-cost sensor that would require small volumes of samples to ...


Tethys: A Software Framework For Web-Based Modeling And Decision Support Applications, Norm Jones, Jim Nelson, Nathan Swain, Scott Christensen, David Tarboton, Pabitra Dash 2016 Brigham Young University

Tethys: A Software Framework For Web-Based Modeling And Decision Support Applications, Norm Jones, Jim Nelson, Nathan Swain, Scott Christensen, David Tarboton, Pabitra Dash

David Tarboton

We have developed a software framework called Tethys to aid in the creation of web-based water resource modeling applications. This suite is a Python-based scripting environment that leverages open source tools for geoprocessing of spatial data, map rendering and visualization, distributed computing, and database management. The system makes it possible to deploy a calibrated, high-resolution watershed or surface water model as a web-based application for decision support. The framework provides data managements, access to computing resources, and pluggable components (e.g. plots, maps and user controls) that enable rapid development of modeling applications. We have used the system to develop ...

Anthony Williams

The purpose of this research program was to determine the strength, strain, fatigue, temperature, and other corresponding behavioral characteristics of concrete sandwich wall panels containing the new Delta TieRTM fiber reinforced polymer (FRP) tie connector produced by Dayton/Richmond, a brand of Dayton Superior. The scope of this program included a matrix of three full-scale 40'-0'' wall panels subjected to a 100°F temperature differential, and a matrix of six elemental specimens, three with the ties oriented in the strong direction (parallel tie orientation) and three with the ties oriented in the weak direction (perpendicular tie orientation), subjected to ...
