Post-Earthquake Fire Assessment Of Steel Buildings, Yi Li, Rachel Chicchi, Amit H. Varma
Post-Earthquake Fire Assessment Of Steel Buildings, Yi Li, Rachel Chicchi, Amit H. Varma
The Summer Undergraduate Research Fellowship (SURF) Symposium
Resilience of structural systems after hazardous events is a crucial concern of building design. An abundance of research has focused on hazards such as seismic and fire separately. This project conducted a multi-hazard study on steel buildings considering both seismic and fire damage. A literature review of the behavior of steel-framed buildings due to fires after earthquakes, known as post-earthquake fires (PEF), is offered. The new PEF methodology, delivered in this study, starts with creating a three dimensional (3D) model of the examined steel building using the finite element method software, ABAQUS. Next, varying intensities of seismic and fire hazards …
Modelling Of Phase Transforming Cellular Material (Pxcm), Chidubem N. Enebechi, Yunlan Zhang, David Restrepo Arango, Pablo Zavattieri
Modelling Of Phase Transforming Cellular Material (Pxcm), Chidubem N. Enebechi, Yunlan Zhang, David Restrepo Arango, Pablo Zavattieri
The Summer Undergraduate Research Fellowship (SURF) Symposium
Phase transforming cellular materials (PXCMs) are a new class of materials that can go through large deformation and return to their original configuration. Currently, there are reliable cellular materials that can resist large deformation, for example, honey comb; however, when these materials are compared to PXCMs, they cannot stay in their elastic range. The biggest advantage about PXCMs is that they are not only inexpensive materials, but they are also highly-durable and they absorb and dissipate high amounts of energy. The main concept behind PXCMs is that they contain unit cells that have stable configurations. Each stable configuration of the …
Electrochemical Removal Of Lead In Water With Multi-Wall Carbon Nanotube Filters, Benjamin M. Stryker, Sol Park, Zhi Zhou
Electrochemical Removal Of Lead In Water With Multi-Wall Carbon Nanotube Filters, Benjamin M. Stryker, Sol Park, Zhi Zhou
The Summer Undergraduate Research Fellowship (SURF) Symposium
Heavy metals, such as lead, are highly toxic and typical removal techniques are costly for household applications; causing serious public health risks and economic burdens. Previous studies using electrochemical filtration showed that singe-wall carbon nanotube membranes (SWCNTs) were effective at removing lead, but the use of less expensive multi-walled carbon nanotubes (MWCNTs) has not been fully explored. Therefore, there is a critical need to determine if MWCNTs are cost-effective for the removal of lead in water. The removal efficiency of lead(II) ions in an aqueous solution was evaluated in a flow-through filtration system over 50 minutes at 1.5 mL/min. Calcium …

A Time-Series Forecasting Model For Windhoek Rainfall, Namibia, Godfrey T. Pazvakawambwa
A Time-Series Forecasting Model For Windhoek Rainfall, Namibia, Godfrey T. Pazvakawambwa
Andrews Research Conference
The objective of the study was to use time series forecasting techniques to model Windhoek rainfall based on secondary monthly data from 1891 to 2011. Descriptive summary statistics in the form of measures of centrality and dispersion, time series plots, and autocorrelation functions were generated using R time series statistical software. The Box Jenkin’s ARIMA modelling procedure (model identification, model estimation, model validation) was used to determine the best models for the data. Model diagnostics based on residual analysis were performed to assess the adequacy of the identified models. The final model was then used to forecast monthly rainfall for …
Fe Analysis Of Alternative Thermal Breaks For Steel Buildings, Salih Q. Mahmood
Fe Analysis Of Alternative Thermal Breaks For Steel Buildings, Salih Q. Mahmood
Student Research Symposium
“Thermal bridge” is a term used for structural or non-structural elements that have higher heat transfer than any other elements or spots in the building envelope, reducing the efficiency of the building thermal insulation. About 20% of the heat occurs via such thermal bridges. Thermal insulations (thermal breaks) are used within a steel connection to mitigate the effect of thermal bridges. In this research, connections with steel fillers studied by Dusicka (2007) were simulated using the finite element (FE) program ABAQUS. The results from the FE model were validated with those from the experimental work done by Dusicka (2007) and …
Monitoring Of Applied Stress In Concrete Using Ultrasonic Full-Waveform Comparison Techniques, Ali Hafiz
Monitoring Of Applied Stress In Concrete Using Ultrasonic Full-Waveform Comparison Techniques, Ali Hafiz
Student Research Symposium
Ultrasonic testing is a non-destructive approach commonly used to evaluate concrete structures. A challenge with concrete is that it is heterogeneous, which causes multiple wave scattering resulting in longer and more complex wave paths. The recorded ultrasonic waveform can be divided into two portions: the coherent (or early) and the diffuse (or Coda) portion. While conventional methods only use the coherent portion, e.g. the first wave arrival to determine the wave velocity, we are interested in the entire waveform, i.e. until the wave amplitude is completely dampened out. The objective of this study was to determine what portion of the …

Future Of The Mutcd, Steven G. Jewell P.E., Ptoe
Purdue Road School
The current edition of the national MUTCD was published in the Federal Register as a final rule in December 2009, effective on January 10, 2010. Most people probably don’t realize that this major tool of our trade is a living document that is under constant review and revision. The MUTCD is legally produced and maintained by FHWA. It usually gets officially revised and republished about every 6-10 years. There are a lot of legal issues and hoops that FHWA must progress through, including public review and documentation, to republish the Manual. Because of the constant changing and improving technology, FHWA …

Deployment And Evaluation Of Sinusoidal Rumble Strips, Jijo K. Mathew, Andrew Balmos, Dana Plattner
Deployment And Evaluation Of Sinusoidal Rumble Strips, Jijo K. Mathew, Andrew Balmos, Dana Plattner
Purdue Road School
Centerline and edge line rumble strips are effective tools for reducing crashes, but the resulting noise of rumble strip incursions can be disruptive to nearby residents. Sinusoidal rumble strips are emerging as quieter rumble strip construction technology. In this session we will discuss the design, construction, and evaluation of sinusoidal rumble strips on IN 1 in Fort Wayne.
Portable Signals: Indot Design Guidance And Specifications, Joseph Bruno
Portable Signals: Indot Design Guidance And Specifications, Joseph Bruno
Purdue Road School
Until recently portable traffic signals, which are mounted on towable trailer supports, were not allowed in Indiana. However, portable signals have many advantages over fixed temporary signals, so the Indiana Manual on Uniform Traffic Control Devices was revised to allow them, and specifications for their use are now in place. This presentation provides an overview of portable signals, including INDOT’s current design and specification requirements for these devices.

The Potential Of Elephant Grass (Pennisetum Purpureum Schum), An African Indigenous Grass, In Bioethanol Production: A Decarbonization Alternative For The Shipping Industry, Lawrence Kuroshi Phd
MARENER 2017
While it is true that fossil fuel based energy which is non-renewable has contributed immensely to global economic growth, it has brought with its usage the emission of carbon dioxide (CO2), a principal greenhouse gas. Studies using business as usual (BAU) model has predicted that the emission of CO2 into the atmosphere will increase by 50 to 250% by the year 2050 with perhaps a commensurate increase in the global carbon footprint. The shipping industry has remained a major contributor to this global carbonization. Concern over this increasing concentration of carbon dioxide in the atmosphere, has intensified interests in developing …
