  • Dynamic properties of naturally frozen ice

    Creator:
    Hammer, Theodore A.
    Abstract:
    In recognition of the need to determine dynamic properties of naturally frozen materials, a research project was conducted to measure the dynamic properties (dynamic moduli and damping ratio) of naturally frozen wedge ice samples obtained from the Fairbanks, Alaska area. Cyclic triaxial and resonant column test systems were employed to...

  • Treatment of activated sludge process effluent by carbon adsorption

    Creator:
    Davis, Stewart Lee
    Abstract:
    An evaluation of the service time of an activated carbon adsorption column and the organic carbon removal efficiency treating activated sludge process effluent was completed at aerator detention times of three, five, and ten hours. Parameters used for evaluation of treatment were biochemical oxygen demand, chemical oxygen demand, total organic...

  • Scale effects on reinforced concrete beams strengthened for shear with discrete externally bonded carbon fiber-reinforced polymer U-wraps

    Creator:
    Dawson, Matthew Ryan
    Abstract:
    Current ACI design provisions for shear in reinforced concrete (RC) beams strengthened with externally bonded carbon fiber-reinforced polymer (CFRP) U-wraps may not adequately account for the effect of scale. This paper describes tests of 6 geometrically scaled beams to identify possible scale effects of such beams. Results indicated that effective...

  • Deterministic and stochastic control of nonlinear oscillations in ocean structural systems

    Creator:
    King, Paul E.
    Abstract:
    Complex oscillations including chaotic motions have been identified in off-shore and submerged mooring systems characterized by nonlinear fluid-structure interactions and restoring forces. In this paper, a means of controlling these nonlinear oscillations is addressed. When applied, the controller is able to drive the system to periodic oscillations of arbitrary periodicity....

  • Analysis of diagonally cracked conventionally reinforced concrete girders in the service load range

    Creator:
    Robelo, Melissa J.
    Abstract:
    Performance evaluation of conventionally reinforced concrete (CRC) bridge superstructure elements with diagonal cracks is of interest to the bridge engineering community. Standardized methods to predict service-level stress magnitudes in cracked bridge girders under combined bending and shear forces are not available. An analysis procedure was developed to determine the response...

  • Experimental and analytical evaluation of conventionally reinforced deck-girder bridge bent caps with vintage details

    Creator:
    Senturk, Ahmet Ekin
    Abstract:
    Many conventionally reinforced concrete deck girder (RCDG) bridges were built in the US during the 1950s, throughout the expansion of the Interstate System. Designs followed the AASHO standard of the time, which permitted higher shear stress in concrete and reduced detailing requirements than permitted by current specifications. Many of these...

  • The fate of specific organisms in a receiving stream

    Creator:
    Henshaw, Thomas Lamond
    Abstract:
    One of the major items in any program of municipal sanitation is the double problem of water supply and waste water disposal. Since streams are the general source of water supply and also the final receptacle for sewage, this dual use of the stream often leads to complications. Sewage and...

  • The degradation of kraft pulping wastes in estuarine waters

    Creator:
    O'Neal, Gary Lewis, 1938-
    Abstract:
    The degradation of kraft pulping wastes in estuarine waters was measured in terms of the following parameters: five-day 20°C B.O.D., the Pearl-Benson Index, and toxicity to the bay mussel (Mytilus edulis L.). The waste tested was the total effluent from a combined pulp and paper mill producing 430 tons of...

  • Applications of Marine Radar Wave Observation Systems

    Creator:
    Meskill, Shay J.
    Abstract:
    This project utilized both shore-based and shipboard commercial marine radar technology to collect wave statistics. In the first application a shore-based system was installed at Yaquina Bay in Newport, Oregon in order to collect real-time wave information. This information was collected under the auspices of the Northwest Association of Networked...
