Simulation Of Temperature And Stress Fields During Rcc Dam Construction, Ronaldo Luna, Yongfu Wu

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The worldwide experience in the construction of roller-compacted concrete (RCC) dams together with the use of numerical solutions, allows the simulation of different scenarios in a computer. It is well documented that thermal control is one of the most important problems for RCC dam construction. The dam temperature changes due to the heat produced by the internal hydration of concrete and the environmental boundary conditions influencing the elastic modulus and creep properties of concrete. The construction process was simulated to study how the temperature and stress change during dam construction. The numerical methodology considers the effect of temperature on the …

The Legacy Of Modern Urbanism In Brazil: Paradigm Turned Reality Or Unfinished Project?, Vicente Del Rio, Haroldo Gallo

City and Regional Planning

The Modern Movement ideals of transformation and progress coincided with the national spirit and zeitgeist of the 1930s Estado Novo in Brazil. Despite a persistent conflict between distinct urbanist views a progressive approach of urbanism became eventually predominant. Its strong impact on urbanist manifestations reached its climax with the construction of Brasilia. This paper explores some negative aspects of the modern legacy in Brazilian urbanism, but by acknowledging that Modern Movement ideals helped to establish a great sense of social consciousness and promoted a common aim, also the creation of a particular identity is recognized. By strengthening local elements of …

An Optimized Lifetime Reliability-Based Inspection Program For Deteriorating Structures, Allen C. Estes, Dan M. Frangopol

Architectural Engineering

No matter how well they are designed, all civil engineering structures will deteriorate over time and a program of lifetime inspection, maintenance and repair represents a substantial portion of the total lifetime cost of most structures. An optimized inspection program is the key to making appropriate repairs at the right time to minimize cost and maintain an appropriate level of safety in a structure. When a visual inspection will not provide the necessary level of information, some other non-destructive evaluation method is often needed. This study summarizes a methodology for optimizing the timing, the frequency, and the type of inspection …

Deformation In Concrete With External Cfrp Sheet Reinforcement, Joseph M. Tripi, Charles E. Bakis, Thomas E. Boothby, Antonio Nanni

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

A detailed experimental investigation of local and global deformations of tensile loaded, cracked, rectangular, concrete prisms reinforced with externally bonded carbon fiber reinforced polymer (CFRP) sheets was carried out. High and low modulus sheets were applied using three different thicknesses of epoxy interlayer between the sheet and concrete. It was found that the stiffness of the CFRP sheet had a dominant effect on global tension stiffening, whereas interlayer thickness had a dominant effect on local load transfer and damage formation. Thicker interlayers transferred load into through-cracked concrete over longer transfer zones, thereby increasing the spacing of subsequent cracks in the …

Terminus A Quo: An End From Which A Starting Point: The Auto-Terminal, Garrett M. Singer

Architecture Thesis Prep

"The intent of this thesis is to develop a new civic order for parking structures in the urban context. The thesis investigation will exist on two primary parts. The first area of investigation will deal with an urban design and analysis of parking as gateways of arrival to Manhattan. Tis will serve as entry nodes for all automobile passages into the city. The second half of the thesis is an investigation of the transformation of the parking garage, which has typically been seen as an eyesore, into an elegant structure."

Local Bond-Slip Relationship For Frp Reinforcement In Concrete, Francesco Focacci, Antonio Nanni, Charles E. Bakis

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The objective of this paper is to define a rigorous numerical method to calibrate parameters of a given local bond-slip relationship using experimental results of pullout tests, taking into account the distribution of the slip and bond shear stress throughout the bar. The proposed method involves finding parameters of a given bond-slip relationship, such that results of pullout tests can be predicted in terms of applied pullout force and consequent slip at the loaded end and slip at the free end. The method is applied to some experimental data, and the results are discussed. For the application of the proposed …

Contemplation On Built Heritage In Ireland: Between Destruction And Preservation, Rumiko Handa

Architecture Program: Faculty Scholarly and Creative Activity

This paper will examine the fate of several buildings in Dublin, Ireland, constructed during the British rule. The decision between destruction and preservation of such buildings naturally rested heavily on the governments' political attitudes after the Irish independence of the 19205. For example, while the City Corporation let many Georgian row houses fall to vandalism and/or destruction, the Office of Public Works recovered a number of buildings as part of a national built heritage. For example, the former Royal Hospital now serves as the Irish Museum of Modem Art. A number of questions arise, however, concerning architectural signification, which bear …

Match-curing technology was used to investigate the influence of concrete temperature development during hydration on the mechanical and material property performance of prestressed and precast HPC beams. These members were fabricated for use in two recently constructed HPC bridges in Texas. The investigation was conducted in conjunction with the …

Applicability Of Ozone In Small Drinking Water Systems, Craig D. Adams, Justin Sutherland

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

The use of ozone in water treatment plants is expanding rapidly in the United States. Ozone offers excellent disinfection properties (including chlorine-resistant pathogens) and does not form trihalomethanes. Additionally, ozone can be used to achieve or control many other water quality parameters such as color, taste and odor, and inorganic and organic contaminant concentrations. Control of ozone's disinfection byproducts such as bromate (formed in high bromide waters) is required. This presentation will review the synergistic effects of ozone applicable to use in small water treatment plants.

Upgrading Missouri Transportation Infrastructure: Solid Reinforced-Concrete Decks Strengthened With Fiber-Reinforced Polymer Systems, T. Alkhrdaji, Antonio Nanni, R. Mayo

Civil, Architectural and Environmental Engineering Faculty Research & Creative Works

More than 40 percent of the bridges in the United States need repair, strengthening, or replacement. Because of limited funds, many states are forced to post load restrictions on their bridges as a temporary measure. Recently, fiber-reinforced polymers (FRPs) have emerged as a practical solution for repair or strengthening of highway bridges. Since there are no nationally accepted specifications for design and construction with bonded FRP reinforcement, the Missouri Department of Transportation (MoDOT) has funded a research program aimed at validating the design and analysis procedure through strengthening and testing to failure of bridges under realistic highway loading and conditions. …

Roosevelt Island: Completing An Urban Community, Karin M. Kilgore

Architecture Senior Theses

The thesis became an architectural exploration of what makes neighborhood and community at two scales: at the scale of the city (macrocosm), represented by the urban plan; and at the scale of the individual (microcosm), represented by the concept of the house and housing. At these two contrasting scales, the main focus of the study was to explore how an urban design can shape community and to explore the role that housing plays in the making of urban fabric/neighborhood. These two main issues of urban planning and housing prototypes, and the set of questions they generated, became the framework for …
