    • Unbonded Pre-tensioned Bridge Columns with Hybrid Fiber-Reinforced Concrete Shells 

      Finnsson, Gunnsteinn (2013-07-23)
      Many bridges in the United States are getting old and will need to be replaced in the near future. If these bridges are constructed with conventional cast-in-place methods, this construction will cause traffic congestion, ...
    • Unbonded Pre-tensioned Bridge Columns with Rocking Detail 

      Schaefer, Jeffrey (2014-02-24)
      A new pre-tensioned precast bridge system has been developed that provides seismic regions the means to construct high-performance bridges that can be built quickly. The columns are designed to rock as rigid bodies, and ...
    • Understanding Activity Location Choice with Mobile Phone Data 

      Wang, Menglin
      Abstract. Research on the variability in travel behavior, i.e. how individuals repeat or change their travel behavior over time, has a long history. An understanding of variability not only facilitates behavior modeling ...
    • Understanding Recent Snow Cover Changes in the Pan-Arctic 

      Shi, Xiaogang (2013-07-23)
      Over the pan-Arctic land area, surface air temperature (SAT) has risen by almost twice the global average in recent decades, and many other changes have been observed across the region, indicating a system-wide response ...
    • Understanding the causes of streamflow changes in the Eurasian Arctic 

      Adam, Jennifer C. (Jennifer Christine), 1974- (2007)
      Since the 1930s, streamflow from Eurasian rivers discharging to the Arctic Ocean has been increasing. Much of this change has been attributed to increased precipitation, but recent studies show inconsistencies in long-term ...
    • Using Technology to Revolutionize Public Transportation 

      Watkins, Kari (2011-05)
      Public transportation could be an important component of a solution to providing mobility while reducing traffic congestion and the environmental impact of transportation. However, from a customer perspective, a mobility ...
    • Value Proposition of COBie at University of Washington 

      Astaneh Asl, Bita
      Building Information Modeling (BIM), has been practiced for several years by designers and contractors in design and construction phases. After receiving a positive feedback of the BIM in industry, owners are now interested ...
    • Wave Breaking and Turbulence at a Tidal Inlet: Shoals, Currents, & Winds 

      Zippel, Seth
      Field measurements of waves, currents, winds, and turbulence collected from surface drifters at New River Inlet (NC) are used to characterize wave breaking. Breaking regions are identified along drifter tracks by three ...
    • Wave Breaking Dissipation in a Fetch-Limited Sea 

      Schwendeman, Michael Scott (2013-04-17)
      Coupled remote sensing and <italic>in situ</italic> measurements of strongly-forced, fetch-limited waves are applied to assess the role of breaking in an evolving wavefield. Wave growth follows accepted fetch-limited ...
    • Wave-supported gravity currents in continental shelves 

      Hooshmand Salemian, Abbas
      Wave-supported gravity currents (WSGC) are one of the most important processes causing cross shelf sediment transport. This dissertation studies the physics behind WSGC in continental shelves using experimental observations. ...
