Below-Grade Structural Flexibility Study For Seismic-Resistant, Self-Centering, Concentrically- Braced Frames, Derek A.J. Hauff 2016 The University Of Akron

Below-Grade Structural Flexibility Study For Seismic-Resistant, Self-Centering, Concentrically- Braced Frames, Derek A.J. Hauff

Honors Research Projects

Self-centering, concentrically braced frames (SC-CBFs) are seismic-resistant lateral-load resisting systems for buildings that increase the lateral drift capacity in comparison to conventional CBFs. Two different substructures were examined on a six-story and a ten-story building to see which below grade structure was more efficient and how the flexibility from the addition of a basement compares to previous research of SC-CBFs structures without basements.

The study was completed in phases: modeling of forces in SAP2000, sizing of structural members, coding of structure into the modeling program Open System for Earthquake Engineering Simulation (OpenSees), and comparison of the output data.

Agenda: Innovations In Managing Western Water: New Approaches For Balancing Environmental, Social, And Economic Outcomes, University Of Colorado Boulder. Getches Wilkinson Center For Natural Resources, Energy, And The Environment

Innovations in Managing Western Water: New Approaches for Balancing Environmental, Social and Economic Outcomes (Martz Summer Conference, June 11-12)

Many aspects of western water allocation and management are the product of independent and uncoordinated actions, several occurring a century or more ago. However, in this modern era of water scarcity, it is increasingly acknowledged that more coordinated and deliberate decision-making is necessary for effectively balancing environmental, social, and economic objectives. In recent years, a variety of forums, processes, and tools have emerged to better manage the connections between regions, sectors, and publics linked by shared water systems. In this event, we explore the cutting edge efforts, the latest points of contention, and the opportunities for further progress.


Global Sensitivity Analysis Applied To Model Inversion Problems: A Contribution To Rail Condition Monitoring, René Schenkendorf, Jörn Groos 2015 German Aerospace Center

Global Sensitivity Analysis Applied To Model Inversion Problems: A Contribution To Rail Condition Monitoring, René Schenkendorf, Jörn Groos

René Schenkendorf

Rising demands on railroad infrastructure operator by means of profitability and punctuality call for advanced concepts of Prognostics and Health Management. Condition based preventive maintenance aims at strengthening the rail mode of transport through an optimized scheduling of maintenance actions based on the actual and prognosticated infrastructure condition, respectively. When applying model-based algorithms within the framework of Prognostics and Health Management unknown model parameters have to be identified first. Which of these parameters should be known as precisely as possible can be figured out systematically by a sensitivity analysis. A comprehensive global sensitivity analysis, however, might be prohibitive by means ...

Spatially Random Processes In One-Dimensional Maps: The Logistic Map And The Arnold Circle Map, An T. Le 2015 University of Colorado Boulder

Spatially Random Processes In One-Dimensional Maps: The Logistic Map And The Arnold Circle Map, An T. Le

Applied Mathematics Graduate Theses & Dissertations

One way to model in-situ remediation of contaminated groundwater is to consider spatially random processes in nonlinear systems. Groundwater remediation often requires injecting an aquifer with treatment solution, where degradation reactions break down the toxins. As the treatment solution and contaminated water flow through the aquifer, their movement is limited by the types of sediment found in the aquifer, which act as spatial barriers to mixing. The onset of chaos in this system implies the two solutions are well mixed, and thus the contaminants are rendered inert. The spatially random processes explored in this thesis are meant to mimic the ...


Measuring Reliability In Dynamic And Stochastic Transportation Networks, Zifeng Wu 2015 University of Nebraska-Lincoln

Measuring Reliability In Dynamic And Stochastic Transportation Networks, Zifeng Wu

Civil Engineering Theses, Dissertations, and Student Research

As the traffic demand levels continue to grow in cities, more and more transportation systems experience instability during recurrent and non-recurrent congestion periods. Therefore, reliability has taken on increasing emphases in performance evaluation for transportation agencies, and in performance communication between agencies and the public. Existing reliability-related studies in transportation engineering focus on the long-term reliability of day-to-day travel time variations. This dissertation expands the reliability research literature with studies on the short-term reliability which is valuable for both real-time management and real-time traffic information systems.

This dissertation proposes a level of service reliability metric for system evaluation. Instead of ...

Love Is A Two Way Street, William W. Riggs, John Gilderbloom 2015 California Polytechnic State University - San Luis Obispo

Love Is A Two Way Street, William W. Riggs, John Gilderbloom

William W. Riggs

A half a century ago, we were in love with our streets. They were also living things. They were the open-air living room of our society, the conduct for neighborhood play and discussion, the glue of our social fabric. One of the key urban theorists of the 20th century, Jane Jacobs wrote in Fortune Magazine that the street “…works harder than any other part of downtown. It is the nervous system; it communicates the flavor, the feel, the sights. It is the major point of transaction and communication. Users of downtown know very well that downtown needs not fewer streets ...

Sorption Of Aqueous Fe(Ii) On Goethite Investigated With Stable Oxygen Isotopes, Pu Yue

Civil Engineering Master's Theses

This thesis work is aimed at examining the oxygen atom mixing between common iron(III) oxides and Fe(II)aq solution during the sorption process. First, 18O labeled iron(III) minerals were used in batch sorption reactors to study the exchange of oxygen atom within the Fe(II)aq - iron(III) oxide system. Results showed a much lesser extent of oxygen mixing than reported Fe mixing from previous studies, even when dissolved Fe(II) is present. The oxygen mixing extents are 3.95 % more for goethite and 9.66 % more for ferrihydrite than their respective controls within 14 days ...


A Framework For Estimating Labor Productivity Frontiers, Nirajan Mani 2015 University of Nebraska-Lincoln

A Framework For Estimating Labor Productivity Frontiers, Nirajan Mani

Construction Systems -- Dissertations & Theses

The efficiency of construction operations is typically determined by comparing actual versus historical productivity. This practice is accurate if historical data reflects optimal values. Otherwise, this comparison is a gauge of relative rather than absolute efficiency. Therefore, in order to determine absolute efficiency, one must compare actual versus optimal productivity. Optimal productivity is the highest sustainable productivity level achievable under “good management” and “typical field conditions,” while the productivity frontier is the theoretical maximum achievable under “perfect conditions.”

The productivity frontier is an abstraction useful in the estimation of optimal productivity of construction operations. This research contributes to the body ...

Validating And Applying Snl-Efdc To Current-Energy-Capture-Devices Simulation, Scott James, Mary Cardenas, Chris Hirlinger

Mary Cardenas

With the growing focus on renewable energy, there is increased interest in modeling and optimizing current energy capture (CEC) devices. The interaction of multiple wakes from CEC devices can affect optimal placement strategy, and issues of environmental impacts on sediment transport and large-scale flow should be examined. Numerical models of four flume-scale experiments were built using Sandia National Laboratories’ Environmental Fluid Dynamics Code (SNL-EFDC.) Model predictions were calibrated against measured velocities to estimate flow and turbine parameters. The velocity deficit was sensitive to αmd, the dimensionless Smagorinsky constant related to horizontal momentum diffusion, as well as the k-ε turbulence parameters ...

Velocity Distributions And Wall Pressures In A Scale Model Gated Box Culvert Control Structure, Alexander L. Evans 2015 University of Nebraska-Lincoln

Velocity Distributions And Wall Pressures In A Scale Model Gated Box Culvert Control Structure, Alexander L. Evans

Civil Engineering Theses, Dissertations, and Student Research

The South Florida Water Management District (SFWMD) manages a system of canals and structures that control the flow through several large storm water treatment areas (STA). The present project was initiated because of the partial failure of a three-barrel, gated box culvert structure that belongs to the system. The structure has a forebay with three sluice gates that control the flow into three 8 ft by 8 ft box culverts. Settling and partial failure of the culverts in the structure was presumably caused by piping of sediment through joints in pre-cast sections of culvert. It was hypothesized that both unsteady ...
