  • Design and fatigue behavior of near-surface mounted CFRP bars for shear strengthening of RC bridge girders

    Creator:
    Johnson, Brandon Ang
    Abstract:
    Carbon fiber reinforced polymer (CFRP) materials are emerging as an effective means of strengthening and rehabilitating bridges. Near surface mounting (NSM) is a newer technique for application of CFRP for retrofitting of bridge members that provides advantages over conventional strengthening techniques. The technique is still new and uncertainties remain regarding...

  • Light-frame versus timber frame : a study in quantifying the differences

    Creator:
    Malone, Brian P.
    Abstract:
    The objective of this study was to compare light wood framing and traditional timber framing quantitatively through environmental impact assessment and load path analysis. This research was inspired by a traditional timber frame structure constructed in Vermont in 2011, and the design of structures considered within reflect the general characteristics...

  • Alkali-silica reaction in concrete containing recycled concrete aggregates

    Creator:
    Adams, Matthew P.
    Abstract:
    Using recycled concrete aggregate (RCA) as a replacement for natural aggregate in new concrete is a promising way to increase the overall sustainability of new concrete. This has been hindered, however, by a general perception that RCA is a sub-standard material due to the lack of technical guidance, specifically related...

  • Numerical response of concrete-lined tunnels crossing active faults

    Creator:
    Lange, Stephanie
    Abstract:
    A challenge for municipal authorities of growing urban areas is to provide larger and faster transportation and utility networks that are safe and resilient to significant disruptions after an earthquake event and other disasters. Urban regions, like the San Francisco Bay or the Los Angeles area, are situated in seismically...

  • Investigating the Current Teaching Evaluation Practices used in Engineering Programs and their Usefulness to Educators

    Creator:
    Villanueva, Keisha A.
    Abstract:
    Evaluation of teaching is used to examine and improve teaching quality in higher education. The literature consists of best teaching evaluation practices that have been developed, yet there is little research that has been conducted which investigates teaching evaluation practices in engineering programs. This thesis represents two manuscripts that explore...

  • 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...

  • Effects of soil slope on lateral capacity of piles in cohesive soils

    Creator:
    Nimityongskul, Nontapat
    Abstract:
    Pile supported bridges are typically constructed near or in a natural or man-made slope and are subjected to lateral loading. The current design method for laterally loaded piles involves the use of Winkler's spring concept with the standard nonlinear p-y curves. The available p-y curves were developed based on results...

  • Effects of soil slope on the lateral capacity of piles in cohesionless soils

    Creator:
    Barker, Paul D.
    Abstract:
    Deep foundations, including driven piles, are used to support vertical loads of structures and applied lateral forces. Many pile supported structures, including bridges, are subjected to large lateral loads in the form of wind, wave, seismic, and traffic impact loads. In many practical situations, structures subjected to lateral loading are...

  • 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...

  • Investigation of Drilled Shafts under Axial, Lateral, and Torsional Loading

    Creator:
    Li, Qiang
    Abstract:
    Drilled shaft foundations provide significant geotechnical resistance for support of structures, such as highway bridges, traffic sign, and signal pole structures, and are used widely to meet their structural foundation requirements. The amount of steel reinforcement in drilled shaft foundations has increased over the past several decades to account for...
