Product Characterization And Headspace Analysis Of Solar Irradiated Aqueous C60 Clusters, Dan Su

Open Access Theses

Buckminsterfullerene (C60) is an important fullerene material that has drawn much attention and is currently being applied in many different fields. It was discovered in 1985. As its production has largely increased to meet these industrial needs, it is obvious that its environmental occurrence, especially in aqueous systems, will occur. To further provide information for environmental toxicity studies and for its risk assessment, this thesis focuses on the photo transformation processes of aqueous C60 clusters (Aqu/nC60), with a particular interest in measuring any mineralization that occurs under different irradiation conditions. Two sets of experiments were conducted to test for CO2 …

Review Of Load Rating And Posting Procedures And Requirements, Raymond Neal Chou

Open Access Theses

All states are required to load rate and post bridges in order to comply with federal standards. Load ratings are performed in order to determine the safe live load capacity of a bridge, considering the existing conditions of the bridge. Based on the load ratings, the bridge is evaluated for load posting or strengthening. The Indiana Department of Transportation (INDOT) was notified that their practice for load rating and posting did not satisfy 23 CFR 650.313, which states that bridges shall be load rated and posted according to an American Association of State Highway and Transportation Officials (AASHTO) manual. The …

A Framework For Coordinating Water Distribution System And Pavement Infrastructure M&R Based On Lcca, Majed Fedhi Alinizzi

Open Access Theses

The disruptions the public faces daily around the world due to urban infrastructure Maintenance and Rehabilitation (M&R) activities are having significant social, economic, and environment impacts on communities. With respect to water distribution systems, there have been millions of water main breaks in the U.S. since January 2000, with an average of nearly 700 water main breaks every day. The majority of these water utilities lie under paved roads, and the Open Cut method is the most widely used technology for repairing water main breakages. Subsequently, this continually increasing pipe breakage requires the destruction of pavements that may be in …

Size And Rate Effects On Mechanical Behavior Of Ultra High Performance Concrete, Boon Him Lim

Open Access Theses

Cor-Tuf, broadly characterize as a reactive powder concrete is a type of cementitious material. Cementitious materials have been observed to exhibit a strain-rate dependent mechanical behavior. The mechanical behavior of cementitious materials can also depend significantly on specimen sizes. Therefore it is crucial to determine the behavior of Cor-Tuf with different specimen sizes for high-rate applications. For this purpose, split Hopkinson pressure bar (SHPB), also known as Kolsky bar was utilized to determine the dynamic behavior of Cor-Tuf for different specimen sizes under uniaxial dynamic compression loading at different strain rates. It was observed that as strain rate increases the …

Modeling The Dynamics Of Household-Level Hurricane Evacuation Timing Decisions, Md. Tawfiq Sarwar

Open Access Theses

Frequent occurrences of hurricanes in the coastal areas of the United States in recent times have indicated the necessity of comprehensive evacuation planning. Failure to ensure efficient and timely evacuation causes devastating impacts including loss of lives and property damages. In order to ensure efficient evacuation, emergency officials need to understand how households make evacuation decisions and how their decisions can be influenced. Households' decisions to evacuate/stay, time of departure, route choice and destination choice are four fundamental behavioral issues in the evacuation process. In this thesis, we develop a joint modeling approach for both household-level evacuation decision and departure …

Laboratory Testing Of Railroad Flatcars For Use As Highway Bridges On Low-Volume Roads To Determine Ultimate Strength And Redundancy, Teresa Lynn Washeleski

Open Access Theses

Railroad flatcars (RRFCs) are a convenient option to replace existing deteriorating bridge structures on low-volume roads. They are typically used as the bridge superstructure by placing two or more flatcars side-by-side to achieve the desired bridge width. Utilizing RRFCs as a bridge allows for rapid construction and greater cost savings compared to traditional practices. These benefits make them an attractive solution for rural communities in Indiana, as well as other states.

Uncertainty remains about the response under higher loads than could be easily achieved in the field and the level of redundancy of railroad flatcar bridges. Using RRFCs as bridges …

Evaluating Different Bridge Management Strategies Using The Bridge Management Research System (Bmrs), Timothy Paul Stroshine

Open Access Theses

This project investigated the effects of varying two different elements of bridge management strategies. The first element was a trigger value (an NBI condition rating for a bridge component) at which a maintenance treatment can be performed. The second element was the budget.

A new software program, the Bridge Management Research System (BMRS), was created to test these elements of bridge management strategies for Indiana's bridge network. BMRS is a simplified version of a previous bridge management software package developed by Purdue University, the Indiana Bridge Management System (IBMS). To test variations in the trigger values, three different bridge management …

Open Access Dissertations

Naderpajouh, Nader Ph.D., Purdue University, December 2013. Interactional Analysis of Emergent Risks in Institutionally Diverse Construction Projects. Major Professor: Makarand Hastak.

Construction projects, as complex systems of systems (SOS), increasingly involve institutionally diverse actors that escalate complexity of the projects. Examples of these actors include the export credit agencies, international organizations such as the World Bank, non-governmental organizations (NGO), regulatory actors, transnational organizations, as well as public and community groups. The observed surge in complexity of the projects aim to enhance their robustness in: i) sustaining the increasing demand for service of these projects, and ii) sustaining the contextual fluctuation …

Bubbledeck, Purdue Ect Team

ECT Fact Sheets Archive

Conventional horizontal concrete slabs are heavy that limit their spans. Enhancement of span results in addition of beams that increases the cost of the structure. Thus, there is a need for a technology that will help in increasing the span by reducing weight of the span. BubbleDeck is a revolutionary construction method that virtually eliminates concrete from the middle of a floor slab between columns that does not perform any structural function, thereby dramatically reducing structural dead weight. BubbleDeck is based on a patented technique - the direct way of linking air and steel.

Documenting The Construction Of A Plain Concrete Bridge Deck And An Internally Cured Bridge Deck, Carmelo Di Bella, John Schlitter, Neal Carboneau, Jason Weiss

Indiana Local Technical Assistance Program (LTAP) Technical Reports

Durable and long lasting concrete is important, especially for bridge decks, which are susceptible to premature cracking and corrosion of the reinforcing steel. To increase the durability of the concrete and its service life, many transportation agencies use high-strength concretes. However, high-strength concretes often have problems with early age cracking due to shrinkage. These cracks can then open a path for chloride ions (found in road salts) to reach the reinforcing steel. The results of this research, which compared bridge installations on two structures in Monroe County, Indiana, confirm that internally cured concrete presents a better alternative to traditional plain …
