  • Model for the prediction of nail withdrawal stiffness

    Creator:
    Atherton, Jon C.
    Abstract:
    An important factor affecting the strength and ultimate load of wood structures is the strength, stiffness and durability of its joints. Therefore, the behavior of nailed joints must be given proper consideration when designing and analyzing wood structures. Presently,formulas for determining the strength of nailed joints under withdrawal loads, as...

  • High cycle fatigue modeling and analysis for deck floor truss connection details

    Creator:
    DePiero, Anthony H.
    Abstract:
    The Oregon Department of Transportation is responsible for many steel deck truss bridges containing connection details that are fatigue prone. A typical bridge, the Winchester Bridge in Roseburg, Oregon, was analyzed to assess the loading conditions, stress levels, and fatigue life of the connection details. The analysis included linear-elastic beam...

  • Nonlinear finite-element modeling of intercomponent connections in light-frame wood structures

    Creator:
    Groom, Kevin
    Abstract:
    Nailed connections have nonlinear load-displacement relations. Modeling these connections in an assembled structure would require a great amount of computational time because of the large number of degrees of freedom. Replacing these connections with energetically-equivalent nonlinear springs reduces the number of degrees of freedom, and leads to computational efficiency in...
