  • 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...

  • Consistency and effectiveness of advisory speeds: an evaluation of current posting techniques

    Creator:
    Rohani, Joshan W.
    Abstract:
    Crash rates are said to be nearly three times higher on curved sections than those on straight sections of rural roadways. As a result, advisory curve/speed signs are standard practice to mitigate these risks on sharp horizontal curves. The industry standard for determining appropriate and uniform speeds for such signs...

  • Changes in hyporheic exchange flow following experimental large wood removal in a second order, low gradient stream, Chichagof Island, AK

    Creator:
    La Nier, Justin
    Abstract:
    Hyporheic Exchange Flow (HEF) is driven by head gradients defined by the hydro-topography of the stream surface, which is controlled by the particular geomorphology of the stream. We quantified the impact of large wood, which typically exerts a strong control on stream morphology, on HEF in a second order, low...

  • Investigation of the behavior of diagonally cracked full-scale CRC deck-girders injected with epoxy resin and subjected to axial tension

    Creator:
    Smith, Matthew T. (Matthew Todd)
    Abstract:
    Article 1: Behavior of Epoxy Injected Diagonally Cracked Full-Scale CRC Deck-Girders. Many cast-in place reinforced concrete deck-girder bridges (RCDG) remain in the national inventory and exhibit diagonal cracking. Epoxy injection has been in use for several decades as a method for sealing diagonal cracks, but the effects on girder behavior...

  • Wood materials and shearwalls of older light-frame residential structures

    Creator:
    Carroll, Cameron T.
    Abstract:
    Light-frame construction practices and materials have changed greatly over the past 100 years. Contemporary research has focused on modern construction; thus, we know a great deal about the behavior of modern lightframe buildings under lateral forces. However, there are many light-frame buildings that were built prior to the introduction of...

  • Efficiency of bioswales in positively effecting storm water quality

    Creator:
    Grenz, Natalie S.
    Abstract:
    Because of the increased need for sustainable construction in an ever urbanizing culture, new sustainable drainage systems are being developed and implemented. Bioswales are becoming an increasingly popular form of sustainable urban drainage used for parking lots and subdivisions. But little is known regarding the effectiveness of bioswales in really...

  • Tidal influence on downstream fining in gravel-bed rivers

    Creator:
    Coles, Derron Rafiq
    Abstract:
    This research examines the downstream fining phenomenon as it operates in coastal gravel-bed rivers of Oregon. Downstream fining is a change in bed composition toward smaller sediment sizes in the downstream direction. Changes in stream flow discharge and channel slope affect the rate of bed-load transport, thereby altering the downstream...

  • Strain distribution in OSB and GWB in wood frame shear walls

    Creator:
    Sinha, Arijit
    Abstract:
    The overall goal of this study was to gain an insight into the load sharing aspect between oriented strand board (OSB) and gypsum wall board (GWB) in shear wall assembly during racking load. More specifically the objectives of the study were to: (1) evaluate qualitatively the load sharing between OSB...

    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...
