  • 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...

  • 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...

  • 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...

  • 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...

  • 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...

  • Dynamic response of steel structures with semirigid connections

    Creator:
    Grant, Joseph Edward
    Abstract:
    The nonlinear response of a ten-story steel structure with semirigid girder connections is studied under conditions of dynamic loading. The dynamic loading used in this study is the North-South component of the May 18, 1940 El Centro, California earthquake. To deal with the complexity of the problem the structure is...

  • 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...

  • Pile group analysis considering rigid and semirigid foundation conditions

    Creator:
    Winchester, Jack LeRoy
    Abstract:
    The structural behavior of pile groups (dolphins) is analyzed considering two types of boundary conditions. First the individual piles of the group are assumed to be rigidly embedded in the soil. In the second analysis the more realistic case is considered where the soil foundation is allowed to yield. The...
