  • The influence of seismic attack and chloride-induced corrosion on a life cycle inventory assessment of different concrete mixtures

    Creator:
    Christiansen, Joshua W.
    Abstract:
    The life cycle assessment (LCA) process is a systematic approach to determining the environmental impacts of different products and processes. LCA is a relative approach that requires functional equivalence for the results to be compared. A method is presented that achieves functional equivalence by equating the reliability indexes being compared....

  • Influence of diagonal cracks on negative moment flexural anchorage performance in reinforced concrete bridge girders

    Creator:
    Goodall, Joshua K.
    Abstract:
    Large numbers of vintage reinforced concrete deck-girder bridges remain in the national bridge inventory. Many of these exhibit diagonal cracking and other distress. Due to the design practices of the time, it is common to observe cracks at locations where flexural reinforcing steel is terminated along the span. The presence...

  • Mooring analysis of the Ocean Sentinel through field observation and numerical simulation

    Creator:
    Baker, Joshua L.
    Abstract:
    This study presents a mooring analysis of the Ocean Sentinel buoy, which is a mobile test platform for Wave Energy Converters. The Ocean Sentinel is owned and operated by the Northwest National Marine Renewable Energy Center (NNMREC) at Oregon State University (OSU). The study involved a field observation as well...

  • Reducing Centerline Rumble Strips Effects on Pavement Performance

    Creator:
    Weaver, Joshua D.
    Abstract:
    Centerline rumble strips (CLRS) have proven to be a cost-effective safety measure in reducing lane departure crashes. However, there are often unintended consequences associated with the installation of CLRS, particularly in rural mountainous areas or snow zones. These consequences include the accumulation of water and ice on the roadway and...

  • Driving simulation : a mechanism for understanding driver response to mobile barriers in work zones

    Creator:
    Swake, Joshua
    Abstract:
    Highway construction projects require temporary changes in roadway characteristics, such as the number of operational lanes, lane path, lane width, shoulder width, and posted speed limit. These modifications which are often temporary in nature have the potential to impact driving performance. Many research efforts have focused on developing standards to...

  • Evaluation of ground motion duration effects on the damage prediction of building and bridge structural and soil-structural systems

    Creator:
    Belejo, Andre
    Abstract:
    The role of ground motion duration on the seismic performance of civil engineering structures remains unclear. Thus, the role of earthquake strong ground motion duration is assessed in a three manuscript thesis, which includes: (1) assessment of the effects of ground motion duration on the seismic performance of a model...

  • 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...

  • Numerical Simulation, Laboratory and Field Experiments, Analysis and Design of Wave Energy Converter and Mooring System

    Creator:
    Lou, Junhui
    Abstract:
    This dissertation studies the coupled fluid-structure interaction (FSI) of a wave energy converter (WEC) and evaluates the design of a WEC mooring system. The research is conducted in support of conceptual development, field test and performance evaluation of WECs as part of the mission of the Northwest National Marine Renewable...

  • The Application of Machine Learning Techniques on Marine Science Models

    Creator:
    Ellenson, Ashley
    Abstract:
    A variety of stakeholders require information about marine systems. In the open ocean, pilots of marine vessels require knowledge about environmental conditions for safe passage and route planning. On the coastline, communities rely on information about nearshore dynamics to increase safety from coastal hazards such as nearshore pollutants, coastal erosion,...

  • The seismic vulnerability of sheet pile walls

    Creator:
    McCullough, Nason J.
    Abstract:
    The seismic performance of port structures has been well documented following recent earthquakes, and indicates that port structures are highly susceptible to earthquake-induced damages. These damages are primarily due to soil liquefaction and the associated ground failures. Sheet pile bulkheads provide vital intermodal and lifeline transportation links between water-side and...
