  • 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...

  • A composite-beam finite element for seismic analysis of wood-framed buildings

    Creator:
    Lee, Chyuan-shen
    Abstract:
    A computer program called SAPWOOD which possesses the capability of performing linear or nonlinear, static or dynamic response including seismic excitation for wood-framed buildings with semirigid connection systems is presented in this study. Program SAPWOOD is a modification of the program NONSAP by adding new elements such as a linkage...

  • Stability of elastically restrained framed structures by matrix analysis

    Creator:
    Albertson, Oran Lester
    Abstract:
    It has been undertaken here to use the matrix method of structural analysis for the determination of the stability of elastically restrained, simple portal frames. This involves the formulation of the stiffness matrix of the structure in terms of the axial force in the members. The stability criterion, when applied...

  • Dynamic analysis of three-dimensional frames

    Creator:
    Scholl, Roger Edwin
    Abstract:
    The response of three-dimensional frames subjected to an arbitrary dynamic force is studied. The method of mode superposition is used to obtain the frame response solution. Two different modeling systems are used to idealize the frame. These are the "discrete mass system" and the "continuous mass system." For an example...

  • A method of seismic design for prestressed concrete highway bridge girders

    Creator:
    Lam, Kwok To
    Abstract:
    The effects of vertical ground motion are particularly significant in the design of highway bridge girders. Conventional codes do not recommend methods for solving the problem. The intent of this work is to suggest an approach for such design. A set of curves for velocity spectra which are the average...

  • Matrix analysis of structures with semi-rigid connection

    Creator:
    Grant, Joseph Edward
    Abstract:
    This thesis presents a matrix analysis of structures with semirigid connections. The stiffness factor of a connection has been assumed to be a constant as represented by the initial relationship of moment versus rotation. Three cases are considered: Case I - structures with semirigid connections, column width and beam depth...

  • Static and dynamic analysis of wood-joist floors by the finite element method

    Creator:
    Polensek, Anton
    Abstract:
    The conventional method for structural design of wood-joist floors is over-simplified and often results in stronger and stiffer floors than necessary. There is also a need to include in the floor design additional criteria dealing with human response to floor vibration such as that due to walking. This study develops...

  • Displacement response of transmission line conductors during random wind gusts

    Creator:
    Cameron, George Richardson
    Abstract:
    The mean square displacement response of a point on a transmission line conductor that is subjected to wind gust generated lift forces is computed. The wind gust velocity and wind gust generated lift forces are treated as random processes in both time and space. A lift force, that is velocity...

  • A linkage finite element for nailed composite wood I-Beams and T-Beams

    Creator:
    Lee, Chyuan-shen
    Abstract:
    With current nonlinear analysis computer capabilities, this study was conducted to develop a linkage element that permits analyses of wood composite structures taking into account possible slip in the nailed joints. The finite elements chosen to represent the wood stud, plywood, gypsum and nails are described. The method as applied...
