  • Experimental behavior of wide-flange beams with web holes

    Creator:
    Horning, Richard Alan
    Abstract:
    Two built-up wide-flange beams with several large holes in each beam were tested to failure. Strains were measured by strain gages at various levels, located at the ends and center of typical holes, and deflections were measured optically at two points on each beam. Lateral bracing was provided to prevent...

  • 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...

  • 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...

  • Structural analysis of symmetrical penstock bifurcations by the finite element method

    Creator:
    Shugar, T. A.
    Abstract:
    A need has existed for an in-depth structural analysis of penstock bifurcations because they form an integral part of hydroelectric power plants. Their geometrical complexity has prevented classical structural analysis from providing an accurate and overall picture of the stresses in the structure. Digital computers and the development of finite...

  • Sediment transport in a gravel-bottomed stream

    Creator:
    Milhous, Robert T.
    Abstract:
    Sediment transport in a gravel-bottomed stream located in the Oregon Coast Range was studied to determine the effects of a single layer of large particles (the armour layer) located at the surface of the bed material. The bed load transport system was studied jointly with suspended sediment transport to understand...

  • Storm runoff response from roadbuilding and logging on small watersheds in the Oregon Coast Range

    Creator:
    Hsieh, Frederic Shu-kong
    Abstract:
    The effects of roadbuilding, logging and burning upon stream runoff responses to individual storms are evaluated for the Alsea experimental watersheds, located in the Oregon Coast Range, The parameters analyzed are peak discharge, induced peak discharge, time-to-peak, and storm-runoff volume. The volume parameter is further sub-divided into total, quick, delayed,...

  • Curriculum synthesis and amelioration : a case study of undergraduate civil engineering

    Creator:
    Hamernik, Robert E.
    Abstract:
    The dynamic philosophy of education as applied to the undergraduate Civil Engineering program has been influenced by such factors as the introduction of new theories, the demands and needs of our society and the personnel responsible for teaching. These changes are reflected in the curriculum as witnessed by a historical...

  • Numerical method for calculating construction pore pressures in embankments

    Creator:
    Steward, John Erwin
    Abstract:
    A computer program was developed for estimating construction pore pressures in embankments without drainage at any location in the embankment at any time during construction. This program incorporated a modification of the Hilf-Brantz method of pore pressure calculation and a finite element method of stress computation. Previous methods of calculating...

  • Random wave velocity field from periodic theory

    Creator:
    Kobune, Koji
    Abstract:
    Random waves are often expressed as a mathematical superposition of an infinite number of sinusoidal components. The mean square spectral density of the water surface elevation is often called the wave spectrum. The zero upcrossing wave heights usually have a Rayleigh probability distribution. However, the design wave concept is still...
