  • Preparation and laboratory evaluation of stationary-phase iron-oxide-based adsorbents for removal of metals from waste waters

    Creator:
    May, Michael Lee
    Abstract:
    Several potential sorbent materials containing iron oxides were prepared and evaluated for potential to remove divalent metals from waste waters. These included a ferrihydrite-coated sand, maghemite incorporated in Dowex[Trademark] ion exchange resin, gothite and two thermally activated ferrihydrites. Attempts to prepare sorbents from steel shot by coating with ferrihydrite or...

  • Aseismic performance of a cable-stayed structure with decentralized H[infinity] control

    Creator:
    Chńg, Guan B.
    Abstract:
    The dissertation uses state-of-the-art structural engineering theories, in parallel with the modern and still-developing control theory of electrical engineering to mitigate the vibratory responses of a double-stayed bridge subjected to strong earthquake ground motions. First, a nonlinear finite element model of the double-stayed bridge subjected to non-uniform (multi-support) earthquake excitations...

  • Equilibrium and Non-equilibrium Thermodynamic Modeling of Cement Pastes Containing Supplementary Cementitious Materials

    Creator:
    Glosser, Deborah B.
    Abstract:
    Thermodynamic modeling of cementitious material is an established tool for predicting the hydrated phase assemblages, pore solution pH, and pore solution composition of mixtures of various chemical compositions and water-to-binder (w/b) ratios. However, traditional thermodynamic techniques have major limitations for modeling mixtures containing supplementary cementitious materials (SCM), and when modeling...

  • An evaluation of coastal Oregon's marginal aggregates

    Creator:
    Clemmons, Gregory H.
    Abstract:
    Coastal Oregon is deficient in quality construction aggregates. There is, however, an abundance of lower quality, or marginal, aggregate available for construction purposes. An evaluation of these marginal aggregates is the purpose of this paper. There are four classes of marginal rocks found on the Oregon Coast. Basalts, high in...

  • Simulation of coastal processes in a circular wave basin

    Creator:
    Katzev, David H.
    Abstract:
    The circular wave basin provides a means of physically modeling the nearshore without the typical problems associated with end walls. Three different coastal processes were examined to demonstrate the use of a spiral wavemaker in a circular wave basin. These were longshore currents, shear waves, and groin circulation. A beach...

  • Ocean wave-soil-caisson interaction

    Creator:
    Tsai, Yau-tang
    Abstract:
    Caissons on permeable seabeds have been designed and constructed for a variety of needs in coastal and offshore engineering. An evaluation of the adequacy of the foundation beneath the structure is required for an economic and safe design. To address this requirement, a two-dimensional analytical model of the foundation response...

  • Laboratory observations and numerical modeling of the effects of an array of wave energy converters

    Creator:
    Porter, Aaron K.
    Abstract:
    This thesis investigates the effects of wave energy converters (WECs) on water waves through the analysis of extensive laboratory experiments, as well as subsequent numerical simulations. Data for the analysis was collected during the WEC-Array Experiments performed at the O.H. Hinsdale Wave Research Laboratory at Oregon State University, under co-operation...

  • Hinged floating breakwater : theory and experiments

    Creator:
    Leach, Patrick A.
    Abstract:
    An analytical model is developed to examine the response and efficiency of a vertical rigid, hinged, floating breakwater. The boundary value problem describing the flow field yields a well-posed Sturm-Liouville problem which is solved by separation of variables for the velocity potentials. The equation of breakwater motion about the breakwater...
