  • Testing and Modeling of a Cross-Laminated Timber Pier-and-Spandrel Seismic Retrofit Solution for Unreinforced Masonry Buildings

    Creator:
    Engleson, Renee M.
    Abstract:
    Cross-laminated timber (CLT) is an attractive building material because it is renewable, promotes fast installation, and possesses a high strength-to-weight ratio. The use of CLT in seismic applications has become increasingly common with the development of post-tensioned CLT rocking wall lateral force resisting systems (LFRS). The CLT pier-and-spandrel system designed,...

  • Breaking Waves Offshore: Measurements and Modeling of Energy Dissipation

    Creator:
    Ticona Rollano, Fadia M.
    Abstract:
    In the presence of strong winds, ocean surface waves dissipate significant amounts of energy by breaking. Here, breaking rates and wave-following turbulent dissipation rate measurements are compared with numerical WAVEWATCH III estimates of bulk energy dissipation. At high winds, the measurements suggest that turbulent dissipation becomes saturated, however the modeled...

  • Elevated Temperature Effects on the Shear Performance of a Cross-Laminated Timber (CLT) Wall-to-Floor Bracket Connection

    Creator:
    Mahr, Kolton J.
    Abstract:
    Connections in mass timber structural systems dissipate energy and transfer lateral forces from mass timber elements such as shear walls and diaphragms, providing critical load paths. Cross-laminated timber (CLT) is a prominent mass timber material used to manufacture wall and floor assemblies. Fire performance research of CLT walls and floors...

  • Evaluation of Topography and Seismicity on Shallow Landslide Susceptibility

    Creator:
    Hess, Daniel M.
    Abstract:
    Shallow landslides are a prevalent concern in mountainous regions that can result in severe societal, economic, and environmental impacts. The challenge is further compounded as the size and location of a potential slide is often unknown. This study presents a generalized approach for the evaluation of shallow landslide susceptibility using...

  • Hybridized framing to modify load paths and enhance wood shearwall performance

    Creator:
    Bultena, Sarah M.
    Abstract:
    Heavy timber framing relies primarily on bracing to withstand lateral loads due to earthquakes and wind events. Bracing configurations in heavy timber framed buildings vary widely and include cross bracing, knee bracing, and other geometries. Many heavy timber frames constructed during colonial American times are still standing, exceeding the expected...

  • Multiobjective Optimization of Wetlands for Attaining Flood, Water Quality and Bird Habitat Benefits

    Creator:
    Noa-Yarasca, Efrain
    Abstract:
    A significant number of historically existing wetlands that naturally stored rainwater and attenuated flood peaks have now been drained and employed as new farming areas. Beyond the water quality and flow problem, this has resulted in loss of natural habitats of diverse ecological species. Restoring wetlands have hence been proposed...

  • Coupled response of compliant offshore platforms

    Creator:
    Young, Raymond A.
    Abstract:
    A three dimensional finite element analysis is developed which is capable of simulating the coupled static and dynamic behavior of compliant ocean structures. Nonlinearities which result from large-deflection, reduced or zero stiffness in compression, and the nonconservative fluid loading are considered. The spatial variation of fluid loading is also addressed....

  • Internal curing of high-performance concrete for bridge decks

    Creator:
    Deboodt, Tyler
    Abstract:
    High performance concrete (HPC) provides a long lasting, durable concrete that is typically used in bridge decks due to its low permeability, high abrasion resistance, freeze-thaw resistance and strength. However, this type of concrete is highly susceptible to the deleterious effects of both autogenous and drying shrinkage. Both types of...

  • Alkali-silica reaction in concrete containing recycled concrete aggregates

    Creator:
    Adams, Matthew P.
    Abstract:
    Using recycled concrete aggregate (RCA) as a replacement for natural aggregate in new concrete is a promising way to increase the overall sustainability of new concrete. This has been hindered, however, by a general perception that RCA is a sub-standard material due to the lack of technical guidance, specifically related...
