  • Investigation, analysis and design of an experiment to test ponding loads on flexible roof systems

    Creator:
    Stark, Duncan
    Abstract:
    While damages due to ponding are common and expensive, provisions for design and construction of flat roof systems lack guidance regarding these loads. The goal of this research is to present methods of designing or building flat roofs that are less vulnerable to this condition. An investigation of the literature,...

    AND DESIGN OF AN EXPERIMENT TO TEST PONDING LOADS ON FLEXIBLE ROOF SYSTEMS by Duncan Stark

  • Experimental and analytical investigation of ponding load effects on a steel joist roof system

    Creator:
    Stark, Duncan
    Abstract:
    Ponding of water on roof systems leading to collapse causes expensive damage and jeopardizes the life safety of building occupants. Current building codes and design specifications for flat roof systems offer minimal guidance in designing for ponding loads. The present research investigated ponding load effects on a long span, lightweight...

  • BOD and toxicity of log leachates

    Creator:
    Atkinson, Sheridan William
    Abstract:
    A series of log storage experiments were conducted to determine whether leachates derived from water storage of logs are acutely toxic to fish. Log segments approximately 18 inches long and 16 inches in diameter were stored in tanks and held submerged for a period of 7 days. The holding water...

  • Adjacent structure response sensitivity to seismic events using the direct differentiation method

    Creator:
    White, William S.
    Abstract:
    The response of adjacent structural systems to earthquake motions is investigated using the finite element framework OpenSees. Results of sensitivity analyses demonstrate that structural response quantities can increase in either or both of the adjacent structures for specific configurations. The structural models used include steel moment-resisting frames and rigid shear...

  • Examining Wave Attenuation Rates and Subsurface Pore Pressures Across Three Marsh Restoration Sill Structures on a Sandy Bed

    Creator:
    Converse, Jordan D.
    Abstract:
    With rising sea levels and more frequent exposure to extreme storms, coastlines worldwide are vulnerable to increased erosion and loss of natural marsh lands. In an effort to lessen these impacts, there is a growing practice of adapting hard or “gray” coastline protection techniques to more nature-based features that promote...

  • Simulation of coastal processes in a circular wave basin

    Creator:
    Katzev, David H.
    Abstract:
    The circular wave basin provides a means of physically modeling the nearshore without the typical problems associated with end walls. Three different coastal processes were examined to demonstrate the use of a spiral wavemaker in a circular wave basin. These were longshore currents, shear waves, and groin circulation. A beach...

  • Regional and Site-Specific Vulnerabilities of the Western Power Grid from a M9.3 Cascadia Subduction Zone Earthquake

    Creator:
    Lathrop Eve D.
    Abstract:
    The likelihood of a Cascadia Subduction Zone (CSZ) earthquake is estimated between 37 to 42% in the next 50 years, leading to strong shaking, liquefaction, landsliding, and other seismic ground failure resulting in major impacts to critical lifelines such as the western power grid. Electrical power is essential for continued...

  • The Effects of Temperature on Electrical Resistivity Measurements of Concrete

    Creator:
    Coyle, Alex T.
    Abstract:
    Measuring resistivity as a method to calculate formation factor is becoming a popular way to evaluate transport properties of concrete. Resistivity measurements are dependent on multiple factors including the resistivity of the pore solution, leaching effects, the degree of saturation of the specimen, the age of the specimen (degree of...

  • Ocean wave-soil-caisson interaction

    Creator:
    Tsai, Yau-tang
    Abstract:
    Caissons on permeable seabeds have been designed and constructed for a variety of needs in coastal and offshore engineering. An evaluation of the adequacy of the foundation beneath the structure is required for an economic and safe design. To address this requirement, a two-dimensional analytical model of the foundation response...

  • Fractal solutions to the long wave equations

    Creator:
    Ajiwibowo, Harman
    Abstract:
    The fractal dimension of measured ocean wave profiles is found to be in the range of 1.5-1.8. This non-integer dimension indicates the fractal nature of the waves. Standard formulations to analyze waves are based on a differential approach. Since fractals are non-differentiable, this formulation fails for waves with fractal characteristics....
