  • Biaxial bending of concrete members with applications to prestressed concrete power poles

    Creator:
    Stephens, Charles Talmon
    Abstract:
    A method of analysis of arbitrarily shaped prestressed concrete members for biaxial bending is given. The stress-strain curve of the concrete is represented by two parabolic segments, and the effects of strain hardening of the steel are included in the analysis. An iterative numerical procedure is used to solve for...

  • Consumptive use of surface water by Willamette Basin municipalities

    Creator:
    Mittelstadt, Richard Lee
    Abstract:
    The consumptive water use of six cities in the Willamette Basin of northwestern Oregon was evaluated for the period 1960-66. Consumptive use ratios were obtained by analyzing data from monthly water supply and sewage flow records. The average annual consumptive use for the six cities was found to be 26...

  • The analysis of directional wave spectra from current and pressure measurements

    Creator:
    Lin, Li-hwa
    Abstract:
    Directional wave spectra have been estimated in this study based upon simultaneous subsurface measurements of current and pressure. Two previously developed methods, the stochastic and deterministic approaches, have been reviewed and restudied. It is demonstrated by means of the Correlation Theorem that the stochastic and deterministic approaches are, under certain...

  • A model study of fabric reinforced earth walls

    Creator:
    Stilley, Alan Neal
    Abstract:
    The concept of placing high strength linear reinforcements in a soil backfill to produce a vertical retaining structure is a recent idea that has been applied with success at a number of locations. Rational procedures have been developed for the design of these structures when the reinforcements consist of long...

  • A large scale model study of placed stone breakwaters

    Creator:
    DeBok, Donald H.
    Abstract:
    The results of three hydraulic model tests to evaluate the stability of a placed stone breakwater are presented and discussed. The prototype breakwater was designed to protect offshore power and port facilities in 60 feet of water and was tested at scale ratios of 1:10, 1:20, and 1:100. The armor...

  • 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...

  • Mass transport in laboratory water wave flumes

    Creator:
    Kim, Tae In
    Abstract:
    A complete solution, exact to second-order, for wave motion forced by a hinged-wavemaker of variable-draft is presented. A solution for a piston type wavemaker is also obtained as a special case of a hinged-wavemaker with negative infinite draft. The existing Stokes inviscid theories for mass transport is extended to include...

  • Coupled dynamics of bouys and mooring tethers

    Creator:
    Idris, Krisnaldi
    Abstract:
    Time-domain models were developed to predict the response of a tethered buoy subject to hydrodynamic loadings. A coupled analysis of the interaction of a buoy and its mooring is included and three-dimensional response is assumed. External loadings include hydrodynamic forces, tethers tensions, wind loadings and the weight of both cable...

  • Requirements for successful irrigation systems in the Senegal River Basin (Mauritania)

    Creator:
    Abba, Fatima Zahra
    Abstract:
    Implementation of a small-scale irrigation project in southern Mauritania is analyzed in this report. The main objective is to demonstrate that small-scale irrigation farming is the best suited solution for Mauritania's agriculture. To reach this objective different steps are taken in this study. The first step highlights the different aspects...
