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...

Optimizing the performance of gypsum wall board in wood frame shear walls

Creator:: Goodall, Scott I.
Abstract:: The overall goal of this project was to design a wood frame shear wall that could withstand greater displacement before damage occurred to the Gypsum Wall Board (GWB). More specifically, the objectives of the study were: (1) to evaluate damage to the GWB in alternative shear wall designs at 1%,...

Evaluation of the torsion test for determining the shear strength of structural lumber

Creator:: Heck, Leanne Renee
Abstract:: The torsion test was evaluated as a method for determining the shear strength of full-size structural lumber. The evaluation involved an experimental length study, an experimental depth study, and a finite element study. The length study consisted of fifty nominal 2x4 specimens, ten specimens for each length, and ten American...

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...

Development of a new mixture proportioning method and assessing the influence of material characteristics on flowing concrete mixtures

Creator:: Hendrix, Greg
Abstract:: Cast-in-drilled-hole (CIDH) piles are often constructed to depths that are inaccessible to internal vibration of the concrete. Internal vibration is necessary to consolidate the concrete and, if not performed, then typically inspection pipes are necessary to detect the presence of voids in CIDH piles. Void detection is critical to assessing...

Use of Virtual Visual Sensors in the Determination of Natural Frequencies of Timber Structures for Structural Health Monitoring

Creator:: Walker, Kristopher
Abstract:: Many nondestructive techniques for structural health monitoring are subjective and based on visual observations of degradation. In addition, dynamic properties of structures are already used to obtain quantitative structural health data. However, most current data collection is limited to localized damage on the structure, rather than global response. Recent research...

A stochastic precipitation event model for use in erosion simulations

Creator:: Istok, J. D.
Abstract:: Mathematical models of the precipitation process are needed to effectively use historical precipitation data in the design and planning of engineering projects and for analysis of watershed runoff behavior. Existing simple models based on the assumptions of independent, identically-distributed random variables are insufficient to describe several features of the historical...

An evaluation of coastal Oregon's marginal aggregates

Creator:: Clemmons, Gregory H.
Abstract:: Coastal Oregon is deficient in quality construction aggregates. There is, however, an abundance of lower quality, or marginal, aggregate available for construction purposes. An evaluation of these marginal aggregates is the purpose of this paper. There are four classes of marginal rocks found on the Oregon Coast. Basalts, high in...
