Assessing durability of reinforced concrete and ductile iron

Creator:: Shields, Silas A.
Abstract:: The first goal of this master’s thesis was to investigate the linkage between a non-destructive testing method, surface resistivity, and premature concrete deterioration brought on by chloride ingress and or freeze-thaw cycling. The experimental method for this project consists of taking surface resistivity measurements of reinforced concrete slabs after they...

Investigation of Iron Passivity and Chloride-induced Depassivation in Alkaline Electrolytes using Reactive Force Field Molecular Dynamics (ReaxFF-MD)

Creator:: Dormohammadi, Hossein
Abstract:: The corrosion and passivity of iron (and carbon steel) in media with different alkalinity as well as iron depassivation have been studied extensively using electrochemical methods and nano-scale surface characterization studies. The electrochemical techniques provide valuable information about the average electrochemical behavior of relatively large metal surfaces, typically in centimeter-square...

Behavior of open grid steel bridge decks under service and fatigue loads

Creator:: Fetzer, Peter C.
Abstract:: Open grid steel bridge decks have been in use for nearly a century. These open grid decks provide an economical and lightweight alternative to traditional reinforced concrete decks. As the transportation infrastructure continues to deteriorate, open grid decks can be used as a cost effective way to rehabilitate structurally deficient...

Numerical assessment of steel plate shear wall with coupling (SPSW-WC) system design procedure

Creator:: Li, Wennan
Abstract:: The Steel Plate Shear Wall (SPSW) system, is an innovative seismic lateral force resistant system, which has experienced increased use over the last three decades. The SPSW system is composed of boundary elements which anchor web plates that develop diagonal tension fields. A number of SPSW buildings have been built...

Experimental research on the behavior and strength of large-scale steel gusset plates with sway-buckling response including effects of corrosion and retrofit options

Creator:: Hafner, Anthony G.
Abstract:: The collapse of the I-35W Bridge in Minneapolis, MN on August 1, 2007 brought into question the design and inspection of gusset plates in steel truss bridges. The experimental tests performed in this research study the sway-buckling strength and behavior of large-scale steel gusset plates in an isolated truss connection....

Numerical simulation of anaerobic reductive dechlorination of CAHs in continuous flow systems

Creator:: Mustafa, Nizar Ahmad
Abstract:: Halogenated organic compounds have had widespread and massive applications in industry, agriculture, and private households, for example, as degreasing solvents, flame retardants and in polymer production. They are released to the environment through both anthropogenic and natural sources. The most common chlorinated solvents present as contaminants include tetrachloroethene (PCE, perchloroethene)...

Introducing the Concept of Foundational Attributes and Project Metabolism to Assess Construction Project Similarity

Creator:: Zhang, Fan
Abstract:: A construction project is considered to be unique due to the process of delivering a customer-designed product, diverse stakeholders involved, the unique location and timeframe of construction, and specific social, economic, and environmental constraints attached to it. The uniqueness of construction projects brought great challenges to the construction industry professionals...

UAS-SfM Lab Exercise

Creator:: Simpson, Chase and Murphy, Robin
Abstract:: The objective of this lab is to gain experience collecting imagery with an unmanned aircraft system (UAS) and processing it in structure from motion (SfM) photogrammetry software to obtain georeferenced data products, including an orthomosaic in GeoTiff format and a point cloud in ASPRS’s LAS format.

Evaluation of the performance of a taut-moored dual-body direct-drive waveenergy converter through numerical modeling and physical testing

Creator:: Elwood, David E.
Abstract:: With energy prices rising and increasing concern about the influence of fossil fuels on climate change, wave energy systems are on the verge of commercial implementation. These first generation wave energy converters utilize either pneumatics or hydraulics to convert the mechanical energy of waves into electricity. For the last several...

Assessing the seismic performance of corroding RC bridge columns

Creator:: Guo, Yisen
Abstract:: Corrosion of reinforcement is recognized as the predominant factor that limits the service life of reinforced concrete (RC) structures exposed to aggressive environments. This corrosion deterioration can lead to damage resulting in capacity loss or even failure. For structures exposed to coastal marine environments or deicing or anti-icing applications, this...
