  • 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...

  • Flexural steel anchorage performance at diagonal crack locations

    Creator:
    Triska, Mary Ann
    Abstract:
    Large numbers of reinforced concrete deck girder bridges that were constructed during the interstate system expansion of the 1950s have developed diagonal cracking in the stems. Compared to the present AASHTO-LRFD standards, the provisions of the 1950s allowed for higher shear stress in the concrete, thus reducing the amount of...

  • Numerical assessment of steel plate shear wall with coupling (SPSW-WC) system design procedure

    Creator:
    Li, Wennan
    Abstract:
    The Steel Plate Shear Wall (SPSW) system, is an innovative seismic lateral force resistant system, which has experienced increased use over the last three decades. The SPSW system is composed of boundary elements which anchor web plates that develop diagonal tension fields. A number of SPSW buildings have been built...
