Shallow foundations are extensively used to support structures of all
sizes and derive their support from near surface soils. Thus, they are typically
embedded up to a few meters into the soil profile. Designers of sha ...
Pile caps are structural elements used to transmit loads from structural columns into pile groups. A pile cap is generally constructed of reinforced concrete and contains only minimal flexural reinforcing steel. Using mo ...
This study consists of three parts: 1) Part A: Limiting Height Evaluation for
Composite Wall Tests, 2) Part B: Mid-Span Deflection Evaluation for Composite Wall
Tests, and 3) Part C: Nominal Axial Strength Evaluation f ...
Open grid steel bridge decks have been in use for nearly a century. These open grid decks provide an economical and lightweight alternative to traditional reinforced concrete decks. As the transportation infrastructure c ...
Laboratory scale microcosm studies were conducted using site specific
groundwater and aquifer solids to assess the feasibility of stimulating indigenous
microorganisms in-situ to biologically transform Trichloroethylen ...
A study was conducted to determine the oxygen uptake rate of
resuspended estuarine bottom sediments and the biodegradability of
the organic matter released during resuspension.
Oxygen uptake was measured on a Gilson D ...
Mycobacterium vaccae JOB5 and Graphium sp. were studied to
evaluate their ability to cometabolize methyl tert-butyl ether (MTBE) and its
metabolites after growth on two different alkanes, propane and iso-pentane.
Both ...
Ex-situ bioremediation of saturated soil contaminated with pentachlorophenol and
2,3,5,6-TeCP is commonly accomplished by landfarming or by treatment in a bioreactor.
Treating saturated, low-permeability soils in biore ...
The composite FRP rebars research at Oregon State University was initiated in
1993 principally to develop a non-metallic hollow reinforcement. It was recognized that
the tensile properties of such reinforcement are unq ...
With the passage of the American with Disabilities Act (ADA) it has become a civil
rights violation to deny access to persons with disabilities to public transportation. The
ADA requires transit agencies to provide acc ...
The Melnikov method is applied to a model of parametrically generated cross-waves in a long rectangular channel in order to determine if these cross-waves are chaotic. A great deal of preparation is involved in order to ...
Cometabolic biodegradation processes are potentially useful for the
bioremediation of hazardous waste sites. In this study the potential application of phenol-oxidizing
and nitrifying bacteria as "priming biocatalysts" ...
Many of the analytical techniques that are currently available are not capable of
analyzing the offtracking of truck and trailer combinations or the path of load overhangs
through a set of curves that are commonly foun ...
It has been suggested that projects in the construction industry are subject to risks more than other industries. However, there is often little parity in allocation of risks in the construction industry. Usually, projec ...
Continuous-flow and batch experiments were conducted with a column reactor
system containing Hanford aquifer material in order to evaluate the potential of in-situ
bioremediation of carbon tetrachloride (CT) at Hanford ...
Time-domain models were developed to predict the response of a tethered buoy
subject to hydrodynamic loadings. A coupled analysis of the interaction of a buoy and
its mooring is included and three-dimensional response ...
This project report presents a laboratory investigation of the dynamic
behavior of saturated alluvial silty soils from sites in Oregon and Washington. The
focus of the study was to document the liquefaction susceptibil ...
