  • Monotonic and Cyclic Testing of Cross-Laminated Timber Diaphragms

    Creator:
    Beairsto, Cody J.
    Abstract:
    Mass timber is emerging as a viable form of construction around the world in new markets for wood buildings. The entrance into these markets has driven the demand for more knowledge to enable designs alongside other structural materials such as steel and reinforced concrete. Large, in-plane tests on cross-laminated timber...

  • Testing and Modeling of a Cross-Laminated Timber Pier-and-Spandrel Seismic Retrofit Solution for Unreinforced Masonry Buildings

    Creator:
    Engleson, Renee M.
    Abstract:
    Cross-laminated timber (CLT) is an attractive building material because it is renewable, promotes fast installation, and possesses a high strength-to-weight ratio. The use of CLT in seismic applications has become increasingly common with the development of post-tensioned CLT rocking wall lateral force resisting systems (LFRS). The CLT pier-and-spandrel system designed,...

  • 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...

  • Settlement predictions for normally consolidated alluvial silt

    Creator:
    Rippe, Arlan H.
    Abstract:
    Settlement of structures built on geologically recent compressible alluvium is a common cause of concern during design. Total settlement results from a combination of: 1) initial elastic settlement, 2) primary consolidation, and 3) secondary compression. The reliability of prediction of total settlement is affected by an understanding of these components...

  • 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...

  • A procedure to identify and evaluate forest arterial and collector road networks

    Creator:
    Kehr, Richard H.
    Abstract:
    This thesis presents a procedure to identify and evaluate forest arterial and collector networks. The procedure identifies those decision criteria important in evaluating both the arterial and collector networks and the specific facilities identified on these networks. The procedure incorporates the decision criteria and results from network and facility analysis...

  • Field verification of a mathematical model for the physical fate prediction of dredged material instantaneously disposed at sea

    Creator:
    Hollings, William H.
    Abstract:
    Dredged spoil plumes are monitored during nine hopper dredge disposal events in 186 foot water depths offshore near Coos Bay, Oregon. Position and solids volume concentration characteristics of the plumes are established. Computer simulations of the monitored events are executed using the WES modified version of the Koh-Chang instantaneous disposal...

  • A large scale model study of placed stone breakwaters

    Creator:
    DeBok, Donald H.
    Abstract:
    The results of three hydraulic model tests to evaluate the stability of a placed stone breakwater are presented and discussed. The prototype breakwater was designed to protect offshore power and port facilities in 60 feet of water and was tested at scale ratios of 1:10, 1:20, and 1:100. The armor...

  • A Multivariate Comparison of Drone-Based Structure from Motion and Drone-Based Lidar for Dense Topographic Mapping Applications

    Creator:
    Simpson, Chase H.
    Abstract:
    Unmanned aircraft systems (UAS), also known as drones, are an increasingly popular method of collecting surveying and mapping data. Two common drone-based mapping techniques are lidar and structure from motion (SfM) photogrammetry, and a frequently-heard (yet nearly impossible to answer) question is: “which is better?” The most common metric for...

  • Evaluating safety at Oregon‘s isolated, high-speed, signalized intersections

    Creator:
    Kopper, Neil H.
    Abstract:
    Isolated approaches at signalized intersections with posted speed limits of 45 mph or greater generally experience large numbers of rear-end and angle collisions. A combination of less attentive drivers, high operating speeds, and less than ideal intersection characteristics can result in crash frequencies well above expected rates. A number of...
