Phase Transforming Cellular Materials (Pxcms) Design And Assembly, Nadia N. Aljabi, Pablo Zavattieri, David Restrepo

The Summer Undergraduate Research Fellowship (SURF) Symposium

We introduce a new class of phase transforming cellular materials (PXCMs) based on locally bistable or metastable unit cells that form periodic microstructures, where the thermomechanical behavior of each unit cell exhibits snap-through type behavior. We propose to explore the capabilities of these new materials to improve structural resistance to damage caused by natural hazards including PXCM in structural members. The main benefits of this material are that it can absorb energy and is reusable. During the first part of this work, a fabrication method for PXCMs based on the assembly material slotted stripes was explored. The 1D unit cell …

Role Of Soil Parameters On Loading Of Buried Structures, Xiao Zhang, Mark D. Bowman, Rafael R. Armendariz Briones

The Summer Undergraduate Research Fellowship (SURF) Symposium

Load rating is the process to evaluate and explore the structural capacity of bridges as much as possible within safety range. As a balance between economy and safety, proper load ratings save money and keep public safe. Knowing the contribution and interaction of each different soil parameter on the loading can significantly reduce the amount of work when load rating those structures. However, for buried structures without plans, such contribution or interaction is never known. This parametric study explores how much each soil parameter of three types of soils can affect the loading of buried structures without plans. An existing …

Seismic Vulnerability Assessment Of Low-Rise Reinforced Concrete Buildings In Kathmandu, Nepal, Prateek Pratap Shah, Santiago Pujol

The Summer Undergraduate Research Fellowship (SURF) Symposium

In seismically active cities like Kathmandu, there often exists a need to assess the seismic vulnerability of a large number of poorly designed buildings within a short period of time. Traditional analysis techniques do not work because they require building data that are either inaccurate or unavailable. One alternative to traditional analysis techniques is to use simple correlations like the Priority Index. This index uses basic building information such as floor area, column area, and wall area to estimate the seismic vulnerability of a building. Following the 2015 Nepal earthquake, 146 low-rise reinforced concrete buildings were surveyed in Kathmandu, Nepal. …

Examining The Hydration And Mechanical Properties Of Cement Paste Containing Cellulose Nanocrystals, Yvette Valadez-Carranza, Charles Y. Chiu, W. Jason Weiss, Pablo Zavattieri, Jeffrey P. Youngblood

The Summer Undergraduate Research Fellowship (SURF) Symposium

Cellulose nanocrystals (CNCs) are a nano-scaled particulae material that has been shown to improve strength in cementitious pastes. One advantage of CNCs compared to other nano-materials is that CNCs are renewable and sustainable. The objective of this investigation is to investigate the influence of additional alkali content on the behavior of CNCs in cement paste. This work evaluates flexural and compressive strength as a function of heat of hydration—which measures the extent of reaction. Previous mechanical tests on cement paste containing cellulose nanocrystals (CNCs) have shown CNCs to improve the flexural strength of cement paste by approximately 30%. Isothermal calorimetry …

Approach To Increasing Indiana Rural Road Safety On Intersections, Ammanuiel A. Kebede, John E. Haddock

The Summer Undergraduate Research Fellowship (SURF) Symposium

In 2009, there were more than 17,000 reported fatal crashes in rural areas of United States which accounted 56 percent of total fatal crashes. This number has not declined in a significant amount since 2009. Studies are undergoing on these rural area roadways, including intersections, to identify the major causes and take the necessary countermeasure. By using previous intersection related fatal and injury crash data, it is possible to identify high-risk intersections to point out and make the appropriate improvement. Five year fatal and injury crash data was collected (2008-2012) for three Indiana rural counties that had the highest frequency …

Seismic In-Plane Response Of Reinforced Concrete Frames With Masonry Infill Walls, Rabab Abdel Karim Al Louzi

Open Access Dissertations

Field data gathered after destructive earthquakes indicate that infill walls interact with reinforced concrete (RC) frames in buildings during an earthquake and could cause failure mechanism different than what the frames are originally designed for. A new method to identify the failure modes of RC frames with infill walls is developed. The method requires only the simple geometric and material properties of the elements involved in the frame- wall assembly. The approach checks various possible failure mechanisms, including those that may evolve depending on how the infill wall may fail during strong shaking, for example, the dynamically evolved captive column …

The Effect Of Maximum Aggregate Size On The Shear Strength Of Geometrically Scaled Reinforced Concrete Beams, Derek Robert Daluga

Open Access Theses

Shear strength of reinforced concrete beams without web reinforcement has been reported to decrease with increases in depth. This is often referred to as a size effect. This reduction in shear strength has been reported to decrease with the use of web reinforcement and increases in maximum aggregate size. ^ The purpose of this study was to test two hypotheses 1) shear strength increases with increases in maximum aggregate size and 2) aggregate gradation affects this increase in shear strength. Maximum aggregate size is defined here as the size of the smallest sieve opening through which all aggregate particles pass. …

Spatial Analysis Of Passenger Vehicle Use And Ownership And Its Impact On The Sustainability Of Highway Infrastructure Funding, Matthew Volovski

Open Access Dissertations

Across the United States, the sustainability of highway funding is at risk due to increasing need and uncertainty in the factors that drive revenue. Past studies on highway funding sustainability have identified that the root cause of changing highway revenue are the shifts in social demographics and economic characteristics. Unfortunately, from the revenue perspective (the focus of this dissertation), the ability of previous research to account for these factors has been rather limited in two ways; first, the inability to accurately assess current regional vehicle use (a typical prerequisite for statistical modeling of highway revenues) due to difficulties associated with …

A Probabilistic Model Of Benefit-Cost Analysis For Highway Construction Projects, Yue He

Open Access Theses

Deterministic method occupies the predominant position in economic analysis. However, by using a single value to estimate the project value, deterministic method would hide the risk under it. Analysts may make incorrect judgments by looking at a value without knowing the likelihood of its occurrence and the consequences of its occurrence. A probabilistic model was developed in this study to address this problem. It was found in this study that the traffic flows on Indiana highways follow logistic distributions rather than normal distributions as generally believed. The application of the probabilistic model was illustrated through a case study. The results …

Quantifying Moisture Transport In Cementitious Materials Using Neutron Radiography, Catherine L. Lucero

Open Access Theses

A portion of the concrete pavements in the US have recently been observed to have premature joint deterioration. This damage is caused in part by the ingress of fluids, like water, salt water, or deicing salts. The ingress of these fluids can damage concrete when they freeze and expand or can react with the cementitious matrix causing damage. To determine the quality of concrete for assessing potential service life it is often necessary to measure the rate of fluid ingress, or sorptivity. Neutron imaging is a powerful method for quantifying fluid penetration since it can describe where water has penetrated, …

Examining Unawareness Of Construction Law Principles From A Small Contractor's Perspective, Ketaki Shiralkar

Open Access Theses

Construction industry encompasses myriads of small trades within itself. If we take a microscope and observe, what looks from outside as one big single unit, is in fact made up of many small cogs of a wheel, important ones though, as without them, the functionality of the industry wouldn't be proper. As much as the existence of these small scale contractor's companies is important, so is their survival. There have been many reasons as to why contractors fail, but this study is limited to focus on one of them, which is, the absence of legal knowledge among employees of a …

Algorithms For Bundling And Pricing Trucking Services: Deterministic And Stochastic Approaches, Rodrigo Mesa-Arango

Open Access Dissertations

Bundling and pricing trucking services is an important strategic decision for carriers. This is helpful when they consider the incorporation of new businesses to their networks, look for economic and optimal operations, and develop revenue management strategies. Reverse combinatorial auctions for trucking services are real-world examples that illustrate the necessity of such strategies. In these auctions, a shipper asks carriers for quotes to serve combinations of lanes and the carriers have to bundle demand and price it properly. This dissertation explores several dimensions of the problem employing state-of-the-art analytical tools. These dimensions include: Truckload (TL) and less-than-truckload (LTL) operations, behavioral …

Distributed Real-Time Hybrid Simulation: Modeling, Development And Experimental Validation, Ali Irmak Ozdagli

Open Access Dissertations

Real-time hybrid simulation (RTHS) has become a recognized methodology for isolating and evaluating performance of critical structural components under potentially catastrophic events such as earthquakes. Although RTHS is efficient in its utilization of equipment and space compared to traditional testing methods such as shake table testing, laboratory resources may not always be available in one location to conduct appropriate large-scale experiments. Consequently, distributed systems, capable of connecting multiple RTHS setups located at numerous geographically distributed facilities through information exchange, become essential. This dissertation focuses on the development, evaluation and validation of a new distributed RTHS (dRTHS) platform enabling integration of …
