  • A method of seismic design for prestressed concrete highway bridge girders

    Creator:
    Lam, Kwok To
    Abstract:
    The effects of vertical ground motion are particularly significant in the design of highway bridge girders. Conventional codes do not recommend methods for solving the problem. The intent of this work is to suggest an approach for such design. A set of curves for velocity spectra which are the average...

  • 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...

  • Near-Surface Response of Beach Sand : An Experimental Investigation

    Creator:
    Adams, Rachel Katie
    Abstract:
    The near-surface region of a coastal sediment bed is complex and dynamic. At some sites, near-surface sediment deposits are susceptible to extreme events, such as tsunamis or other large overflows, which induce high shear stresses on the sediment bed. The specific properties of sediment beds subjected to such extreme loading...

  • System design for Dungeness crab processing

    Creator:
    Adams, Burton Warren
    Abstract:
    Dungeness crab is an important fishery on the Pacific Coast. The processing subsystem of the fishery is hampered by a variety of problems that have acted to impede technological innovations that could improve efficiency and sanitation in seafood plants. This paper provides background for problems encountered by the processors, discusses...

  • Improving Region-Scale Landslide Inventory and Susceptibility Mapping

    Creator:
    Bunn, Michael D.
    Abstract:
    Landslides are a natural hazard that have major societal, economic, and environmental impacts. The understanding of landslides begins with the observation that they are a spatial problem. Spatial relationships have historically been explored with maps, and landslides are no different. Such maps range in focus from inventory maps, which identify...

  • A Regional-Scale Three-Dimensional Susceptibility Model for Enhanced Evaluation of Rainfall- and Seismically-Induced Landsliding

    Creator:
    Mathews, Nicolas
    Abstract:
    Shallow landslides are destructive natural hazards that result in widespread losses, both of infrastructure and lives, throughout the world. To help mitigate the impact of landslide hazards, they are commonly characterized across a regional scale by (1) their location and likelihood using susceptibility maps, (2) their magnitude and frequency using...

  • Numerical Simulations and Microscale Analyses of Offshore Anchor-Granular Material Systems

    Creator:
    Zhang, Nan
    Abstract:
    Anchoring systems are used to hold floating offshore devices (e.g., energy devices, oil platforms) to keep them on their stations. Anchors are embedded into the seabed soils. In some cases, the interface shear between anchor and seabed soils together with anchor self-weight provide the holding capacity of the anchoring systems....

  • Towards the Development of Performance-Based Concrete Mixtures Made with Modern Cementitious Materials Using Thermodynamic Modeling

    Creator:
    Bharadwaj Ravi, Keshav
    Abstract:
    This thesis builds on a modeling tool that has been developed to link thermodynamic modeling and concrete performance. This tool is intended to predict the performance for modern concrete mixtures made with ordinary portland cement (OPC), conventional and novel supplementary cementitious materials (SCMs), and limestone (Ls). The first part of...

  • Development of an ACIP pile-specific load-displacement model

    Creator:
    Adami, Nasim
    Abstract:
    Augered cast-in-place piles, also known as ACIP piles, have been used for more than seven decades in the United States and have gained in popularity due to their relatively quick installation and cost-effectiveness. Owing to the reduced impact on the neighboring environment as compared to some other deep foundation installation...

  • 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...
