  • Applying climate change information to hydraulic and hydrologic transportation infrastructure

    Creator:
    Al Naabi, Rawan Y.
    Abstract:
    Scour is the main cause of bridge failures in the United States. Bridge failures raise a hazard to the safety of the traveling public as well as the massive economic consequences due to the high cost of constructing a new or a replacement bridge. The Oregon Department of Transportation (ODOT)...

  • Experimental and Analytical Studies of Large-Scale Pile Caps

    Creator:
    Al-Sakin, Yasmeen
    Abstract:
    Pile caps are structural elements used to transfer loads from columns to a group of piles, which transfer them to stronger soil layers. Pile cap with horizontal distance between the column and piles less than twice its effective depth is categorized as "deep," where significant nonlinear strain distribution occurs through...

  • Seismic Retrofit of Square Reinforced Concrete Bridge Columns using Titanium Alloy Bars

    Creator:
    Shrestha, Sharoo
    Abstract:
    There are many aging bridges in service in the US and around the world that were not constructed to modern seismic design codes and standards. As a result, they are expected to perform poorly during intense earthquake ground shaking. Older reinforced concrete (RC) bridges, in particular, are often supported on...

  • Influence of Uncertainties in Terrestrial Laser Scanning on Structural Reliability and Bridge Load Rating

    Creator:
    Loving, Carly K.
    Abstract:
    To ensure the safety of the nation’s bridges, the National Bridge Inspection Standards (NBIS) require all bridges to undergo routine load rating analyses to assess their structural capacity. Accurate geometric information for each structure is necessary for load rating analyses. This information is typically ascertained from as-built plans. Still, when...
