  • 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...

  • The Fundamental Behavior of Timber-Concrete Composite Floors in Fire

    Creator:
    Shephard, Annabel B.
    Abstract:
    Timber-concrete composite (TCC) floors have improved strength and stiffness when compared to timber-only floors, allowing for longer spans in buildings and improved life safety. However, North America does not have codes and standards that recognize TCC floors, particularly the improved life safety performance of these floors in fire. Therefore, alternate...

  • Structural Response of High-Performance Fiber-Reinforced Cementitious Composites: Evaluation, Simulation, and Sensitivity Analysis

    Creator:
    Khlef, Feras L.
    Abstract:
    The constitutive behavior of high-performance fiber-reinforced cementitious composites (HPFRCCs) under mechanical loading is characterized by significant tensile properties that play an essential role in the structural response of several applications in structural engineering. The significance of tensile properties of HPFRCCs in structural engineering is the focus of three manuscripts presented...

  • 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...

  • Performance of High-Strength Steel Reinforcement in Shear Friction Applications

    Creator:
    Matus Casanova, Nicolas A.
    Abstract:
    The use of high strength steel reinforcement has the potential to provide economic and constructability benefits when used in reinforced concrete structures. However, more research is needed to justify and confidently allow its use. Current design provisions limit the nominal yield strength of reinforcing steel bars to 60 ksi (420...
