  • Vulnerability of port and harbor communities to earthquake and tsunami hazards in the Pacific Northwest

    Creator:
    Wood, Nathan J.
    Abstract:
    Earthquakes a . tsunamis pose significant threats to port and harbor communities in the Pacific Northwest. Developing effective mitigation and preparedness plans requires a comprehensive understanding of community vulnerability. Research presented here focuses on the vulnerability of ports and harbors to earthquake and tsunami hazards and includes a regional study...

  • Seismic protection of flexible rotating machines using base isolators

    Creator:
    Su, Wen-Chyi
    Abstract:
    Base isolation is an alternative seismic design strategy in which the primary structures and their internal components are uncoupled from the potentially damaging horizontal components of an earthquake by base isolators which attenuate the transmission of horizontal acceleration into the system. Rotating machines are among the key internal components of...

  • Development of rapid visual screening tool for seismic evaluation of wood-frame dwellings

    Creator:
    Lucksiri, Kraisorn
    Abstract:
    During the past several decades, earthquakes have caused extensive damage to buildings, including wood-frame, single-family dwellings, in the United States. In order to mitigate future losses, existing buildings in earthquake prone areas should be evaluated for their seismic safety. This is also an important issue for buildings in Oregon due...

  • The seismic geotechnical modeling, performance, and analysis of pile-supported wharves

    Creator:
    McCullough, Nason J.
    Abstract:
    This dissertation presents the results of a research effort conducted to better understand the seismic performance and analysis of pile-supported wharves. Given the limited number of well-documented field case histories, the seismic performance of pile-supported wharves has been poorly quantified, and the analysis methods commonly employed in engineering practice have...

  • Seismic performance of a pile-supported container wharf structures in rockfill

    Creator:
    Kawamata, Yohsuke
    Abstract:
    Recently, the concept of performance based design has become popular for many types of structures, including port facilities under seismic loading. For the case of pile-supported wharves, the level of performance is generally estimated using the displacement capacity of the structure. Therefore, understanding soil-pile interaction is one of the most...

  • Examination of lateral stiffness and strength of pitched residential roof diaphragms with implications for seismic design.

    Creator:
    Kirkham, William J.
    Abstract:
    There are about 80 million single-family dwellings (SFD) in the United States, predominantly of wood-frame construction. Of these, 68% are owner occupied. A home is typically the largest single investment of a family, and is often not covered by earthquake insurance, even where it is available. Of all SFD in...

  • Response of equipment in resilient-friction base isolated structures subjected to ground motion

    Creator:
    Lei, Kai-ming
    Abstract:
    The response of lightweight equipment in structures supported on resilient-friction-base isolators (R-FBI) subjected to harmonic ground motion and various earthquake ground motions is examined. The equipment-structure base system is modeled as a three degree-of-freedom discrete system (SDOF subsystems). An efficient semi-analytical numerical solution procedure for the determination of equipment response...

  • Performance-based seismic design of light-frame shearwalls

    Creator:
    Kim, Jun Hee
    Abstract:
    Performance-based design has gained interest in recent years among structural designers and researchers. Performance-based design includes selection of appropriate building sites, structural systems and configurations, as well as analytical procedures used in the design process, to confirm that the structure has adequate strength, stiffness and energy dissipation capacity to respond...

  • Evaluating the seismic risk and resilience of an electrical power system

    Creator:
    Chalishazar, Vishvas H.
    Abstract:
    The Pacific Northwest is part of the "Ring of Fire," which is well-known for heavy seismic activity. Numerous active faults in the area have encouraged electric grid managers in the region to more deeply contemplate and proactively intervene to support grid resilience. This research introduces Monte Carlo (MC) based power...

  • Dynamic response of steel structures with semirigid connections

    Creator:
    Grant, Joseph Edward
    Abstract:
    The nonlinear response of a ten-story steel structure with semirigid girder connections is studied under conditions of dynamic loading. The dynamic loading used in this study is the North-South component of the May 18, 1940 El Centro, California earthquake. To deal with the complexity of the problem the structure is...
