  • Static and cyclic response of ecoroof soil

    Creator:
    Kraupa, Travis J.
    Abstract:
    Green technology in the United States has been on the rise over the past few decades in the United States. However, certain green technologies have been developed in the absence of design standards. Ecoroofs, which are vegetated soil masses placed on the top of a building’s roof structure, present several...

  • Right-hook crash causality at signalized intersections

    Creator:
    Jannat, Mafruhatul
    Abstract:
    A Right-hook (RH) crash is a common type of bicycle-motor vehicle crash that occurs between a right-turning vehicle and through-moving bicycle at an intersection. At signalized intersections, RH crashes can occur at the onset of the green or during the latter portion of the green phase. In spite of the...

  • Direct Shear Interface Friction and Linear Motion Shaking Response of Ecoroofs

    Creator:
    Kilroy, Kimberly A.
    Abstract:
    Ecoroofs have become more prominent in recent years. However, there is currently no enforceable standard or building code for the design and construction of ecoroofs across the United States (Kraupa, 2014). Further research is needed to determine how ecoroofs respond to roof motion and to develop an appropriate design standard.The...

  • Framework for Measuring Construction Project Performance using Energy

    Creator:
    Nnaji, Chukwuma A.
    Abstract:
    Over the years, the performance of construction projects has been a main source of concern given the percentage of a project cost associated with poor project performance. As a result of the growing clamor to improve the output of the built industry, comprehensive studies have been conducted to examine the...

  • Development of an ACIP pile-specific load-displacement model

    Creator:
    Adami, Nasim
    Abstract:
    Augered cast-in-place piles, also known as ACIP piles, have been used for more than seven decades in the United States and have gained in popularity due to their relatively quick installation and cost-effectiveness. Owing to the reduced impact on the neighboring environment as compared to some other deep foundation installation...

  • Comprehensive Analysis of PM2.5 Pollution from Construction Activities

    Creator:
    Montadka, Nahush Prabhakar
    Abstract:
    The Construction industry is one of the most hazardous industries in the US.Construction workers, on a daily basis, are exposed to numerous risks while performing arange of activities involving construction, alteration, and or repair. Dust and diesel exhaustemissions from construction equipment are considered harmful to the workers in the longrun....

  • Effect of subduction zone earthquakes on SDOF bridge models

    Creator:
    Long, Yicheng
    Abstract:
    Current bridge design codes do not account for the effects of duration of mega-thrust subduction zone earthquakes. Furthermore, codes and even recent performance-based design methodologies only make use of the peak response quantities (forces, displacements, and ductility demands) and do not account for the increased number of inelastic cycles that...

  • Developing Performance-Based Specifications to Improve the Fatigue Life of Asphalt Pavements in Oregon

    Creator:
    Sreedhar, Shashwath
    Abstract:
    Asphalt concrete fatigue cracking is recognized as a major distress mode in the U.S. The widespread nature of this distress and the data from agency Pavement Management Systems (PMS) suggest that it is an issue with asphalt mixture design and production processes and is not a problem specific to certain...

  • Probabilistic Multi-hazard Earthquake-Tsunami Structural Risk Assessment Framework

    Creator:
    Alam, Mohammad Shafiqual
    Abstract:
    Catastrophic earthquake and tsunami events that resulted in significant loss of life and property over the past two decades have raised the global awareness regarding the need to understand the response of communities and their built environment to multi-hazard extreme events. In recognition to this impending threat to the coastal...

  • Numerical simulation of anaerobic reductive dechlorination of CAHs in continuous flow systems

    Creator:
    Mustafa, Nizar Ahmad
    Abstract:
    Halogenated organic compounds have had widespread and massive applications in industry, agriculture, and private households, for example, as degreasing solvents, flame retardants and in polymer production. They are released to the environment through both anthropogenic and natural sources. The most common chlorinated solvents present as contaminants include tetrachloroethene (PCE, perchloroethene)...
