  • Freeze-thaw durability of reinforced concrete deck girders strengthened for shear with surface-bonded carbon fiber-reinforced polymer

    Creator:
    Mitchell, Mikal Maxwell
    Abstract:
    Long-term durability of surface-bonded carbon fiber-reinforced polymer (CFRP) U-wraps for shear strengthening of reinforced concrete (RC) bridge members remains uncertain due to the limited field experience with these materials. This paper provides experimental results from the testing of full-scale RC bridge girder specimens after exposure to prolonged freeze-thaw cycling. CFRP...

  • Effect of an Idealized Mangrove Forest of Moderate Cross-shore Width on Loads Measured on a Sheltered Structure and Comparison with Predicted Forces

    Creator:
    Mitchell, William T.
    Abstract:
    As coastal communities face increasing chronic and acute hazards, nature-based coastal engineering solutions have experienced a rapid growth in popularity and interest. Recent works on this topic have shown that “Green Infrastructure” may be effective at mitigating coastal hazards and therefore provide sustainable adaptation alternatives to traditional engineering solutions such...

  • 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...

  • 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 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...

    Abstract:
    This dissertation introduces a method which can simulate multi-dimensional Gaussian random processes by the superposition of sine functions The fast Fourier transform technique is incorporated into the simulating method to facilitate saving of computer time. In view of the fact that the fast Fourier transform play important roles in digital...

  • 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...

  • 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...
