  • 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...

  • Dynamic behavior of metal-plate-connected wood truss joints

    Creator:
    Kent, Scott M.
    Abstract:
    The objectives of this research were to evaluate the behavior of actual metal-plate-connected (MPC) tension-splice and heel wood truss joints under seismic loads from the Northridge earthquake (tension-splice joints only) and under loads from a large artificial earthquake (1.0 g's and 0.67 g's maximum horizontal and vertical accelerations, respectively). A...

  • Dynamic response of flexible rotating machines subjected to ground motions

    Creator:
    Su, Wen-Chyi
    Abstract:
    Rotating machine play an important role in modern technology. Compressors in ventilating and cooling systems, pumps in power generation facilities, as well as high speed computer are all examples of flexible rotating machinery that must remain functional during and after a sever earthquake. Recent earthquakes have demonstrated that an aseismically...

  • Deformation-based seismic design models for waterfront structures

    Creator:
    Yang, Dong-Shan
    Abstract:
    Recent experience demonstrates that waterfront structures are vulnerable to earthquake damage. The poor seismic performance of these facilities has been primarily due to liquefaction of backfill and/or foundation soils and the lack of seismic design standards for waterfront structures. The seismic performance of waterfront structures is a key issue 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...

  • Development of a seismic rehabilitation master plan for the Oregon State University campus

    Creator:
    Trautwein, Steven R.
    Abstract:
    The recent increase in awareness of the seismic hazards in Oregon has led to a concern regarding the safety of Oregon State University buildings. While the decision has been made to initiate the seismic rehabilitation of campus facilities, the question of which buildings pose the greatest hazards, and are therefore...
