Compacted aggregate trenches are a method of soil improvement that could be substituted for commonly used aggregate piers in certain geometrical arrangements of shallow foundations. However, this type of ground improvement has little research to support the understanding of their contribution to improved strength of an unimproved clay soil. This...
Cross Laminated Timber (CLT) technology has been growing in the EU and Canada
since the early 1990's and utilizes the mechanical properties of structural grade
lumber to create a strong panel product for use in floor, ceiling and wall systems. The
hypothesis of this project was that CLT panels made...
At the present time only a portion of Corvallis is sewered and a portion of the city still employs the most crude and unhealthful methods of disposal. The district east of Ninth Street, as shown on the map, has an effective system of well constructed sewers, of the combined storm-water...
Traditional braced frames are an efficient and economic means of resisting seismic demands. However, braced frames are prone to story mechanisms, which can result in concentrations of demands and damage during seismic events. Including steel strongbacks in conjunction with traditional braced frames can mitigate story mechanisms. The SBF results in...
This study focuses specifically on the investigation of a new, inexpensive geophone system and its application to monitor wave activity. Studies of seismic observations of coastal cliffs suggest that ground motions generated from local ocean waves may provide a surrogate to limited wave buoy data to quantify the wave contact...
In the United States there are currently two different options for providing safety audits to roadway projects. Traditional audits can be conducted using procedures similar to those in the United Kingdom, or those similar to Australia and New Zealand (Austroads). Another option for conducting safety audits is to use the...
This study explores the influence that the sustainability of hotels has on the choice of hotels. Because of recent concern about global warming and reducing energy consumption, many designers are planning sustainable buildings. But often attractiveness is sacrificed for the goal of making a building sustain in its environment. The...
The intent of this thesi s is to prove whether or not simple moving averages can be
used to predict the future price performance of stocks and outperform the buy-and-hold
method of investing in the stock market. The importance of this research is that if moving
averages can predict future...
The objective of this study was to provide first order observations of bed level changes occurring in streambed simulated culverts throughout an annual period. To accomplish this, 30 culvert sites were selected in Oregon and Washington, and monitored over, at least, a 2 year period. Streambed scour and redeposition data...
Cob is an earthen building material composed of sand, clay and straw. Though cob homes
are presently being built in the Pacific Northwest, there is no applicable building code for this
material. The purpose of this study is to establish estimates for the major engineering parameters,
including both average values...
