  • 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...

  • 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...

  • Nonlinear diffraction theory by an eigenfunction expansion of the Green's function

    Creator:
    Chen, Min-Chu
    Abstract:
    A second-order nonlinear diffraction theory is developed for a large diameter circular cylinder under the action of surface gravity waves of finite amplitude in water of-finite depth. Boundary value problems are derived by using a perturbation expansion and the solutions for the diffracted waves are given in terms of Fredholm...

  • 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...

  • Dynamic response of an offshore structure to measured and simulated stochastic wave forces

    Creator:
    Grecco, Michael G.
    Abstract:
    The dynamic response of an offshore structure to measured and simulated stochastic wave forces is investigated. The theoretical nondeterministic analysis is performed in the frequency domain for a two-dimensional model. The ocean wave system is assumed to be a zero mean, stationary, ergodic Gaussian process described by a one-dimensional wave...

  • An evaluation of the cubic autotape under dynamic conditions

    Creator:
    Plasker, James Robert
    Abstract:
    Accuracy requirements for positioning a vessel in the near shore area have increased in recent years. To meet these requirements several electronic positioning systems have been developed. One such system is the Cubic Autotape Model DM-40. The Autotape is a circular positioning system which utilizes the phase comparison between transmitted...

  • Finite elements analysis of circular cell bulkheads

    Creator:
    Kittisatra, Likhit
    Abstract:
    A mathematical model is developed for the analysis of circular cell bulkheads subjected to gravity loads of cell fill, backfill, lateral pressure, and surcharge load using the finite element method. The finite element circular cell model consists of axisymmetric triangular and/or quadrilateral ring elements for soil and cylindrical shell elements...

  • Large scale model testing of the FMC submerged wave attenuation device

    Creator:
    Huber, David S.
    Abstract:
    This report describes the hydrodynamic testing and evaluation of a one-tenth scale model of the FMC Wave Attenuation Device. The purpose of the test was to quantify the wave attenuation characteristics and structural loading induced by a test program of monochromatic incident waves on the submerged structure. The device was...

  • Computerized safety analysis technique for secondary highways

    Creator:
    Nichols, Kevin Scott
    Abstract:
    Evaluation of the safety hazards along a highway is usually performed at specific locations and on known hazards. But, it is also important to find any unrecognized hazards and their locations. Many factors contribute to accident potential, and the combined effect of several of them could produce a hazard that...
