  • New acoustic emission applications in civil engineering

    Creator:
    Schumacher, Thomas
    Abstract:
    Non-destructive testing methods and applications have become of increasing interest due to the worldwide aging and deteriorating infrastructure network. In the field of Civil Engineering, bridges and bridge components as well as non-structural elements such as roadway pavements for example, are affected. In particular, the Acoustic Emission (AE) technique offers...

  • Performance of wood frame wall with thin shell ECC shear panel

    Creator:
    Lewis, Michael C.
    Abstract:
    The overall goal of this study was to evaluate an alternative to traditional wood framed shear wall construction. This study introduced the innovative idea of using a water and seismic damage resistant, wood-concrete- composite (WCC) construction instead of an all-wood design. The WCC design consisted of a thin shell of...

  • Effects of reference displacement and damage accumulation in wood shear walls subjected to the CUREE protocol

    Creator:
    Langlois, Jeffrey D.
    Abstract:
    The objectives of this study are: (1) to evaluate the effect of reference displacement on wall behavior under fully reversed cyclic loading using the CUREE test protocol and (2) to assess damage accumulation (visible fastener damage and stiffness degradation) for the imposed drift levels. All tests were conducted on identical...

  • Performance of partially and fully anchored wood frame shear walls under monotonic, cyclic and earthquake loads

    Creator:
    Seaders, Peter
    Abstract:
    The objectives of this study were to evaluate the performance of wood frame shear walls under monotonic, cyclic and earthquake loads by: (1) estimating the variability of shear wall performance, (2) comparing the performance of walls under each loading protocol, (3) evaluating the effects of anchorage on wall performance, and...

  • The performance of wood frame shear walls under earthquake loads

    Creator:
    White, Kevin Bradish DelGrande
    Abstract:
    The overall goal of this study is to evaluate the earthquake performance of wood frame shear walls, and more specifically: (1) to compare the performance differences of fully and partially anchored walls under monotonic, cyclic, and earthquake loads, (2) to compare wall performance under earthquake loads with that of standardized...

  • 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,...

  • Nonlinear dynamic analysis of heavy timber frame structures including passive damping devices

    Creator:
    Eiden, Claudia M. T.
    Abstract:
    Engineering analysis of heavy timber structures under dynamic loads is generally lacking. Some literature suggests that heavy timber structures are stiffer than expected, but popular engineering opinion is to the contrary. In addition, prior research has shown that passive friction dampers can be used in timber structures for the intended...

  • Analysis of diagonally cracked conventionally reinforced concrete girders in the service load range

    Creator:
    Robelo, Melissa J.
    Abstract:
    Performance evaluation of conventionally reinforced concrete (CRC) bridge superstructure elements with diagonal cracks is of interest to the bridge engineering community. Standardized methods to predict service-level stress magnitudes in cracked bridge girders under combined bending and shear forces are not available. An analysis procedure was developed to determine the response...

  • Testing and evaluation of flexural reinforcing bars terminating in columns

    Creator:
    Koester, Carl C.
    Abstract:
    Capacity of transverse 1950's vintage reinforced concrete deck girder bridge bent caps with large straight bar anchorages were investigated and evaluated. Eleven subassemblage column specimens were examined with different anchorage lengths, bar groupings, amount of transverse steel, and externally applied axial force. Test results showed an increase in anchorage capacity...

  • Steel confined yielding damper for earthquake resistant design

    Creator:
    Newell, James D.
    Abstract:
    An experimental study of a passive energy dissipation tension-compression yielding brace or buckling restrained brace has been conducted. The Confined Yielding Damper (CYD) consists of a steel yielding core confined within a tube filled with non-cohesive media. The external tube and confined non-cohesive media provide lateral stability to the core...
