The forest products industry often uses intermediate-support cable logging
systems to transport logs from the harvest site to a staging area. A method is presented to assist in the analysis and design of these cable sys ...
An analysis method for moving loads computes the internal demand history in a structural member at integration points of force-based finite elements as opposed to the end forces of a refined displacement-based finite ele ...
Thermal cracking of asphalt concrete pavements is responsible for millions
of dollars in annual maintenance and rehabilitation costs in the United States and
Canada. Thermal cracking is typically associated with low te ...
A general analytical framework was established to investigate the scale-related variabilities in remote
sensing. The variabilities were studied first by investigating canopy structure, canopy interaction with
light, re ...
Quality Function Deployment (QFD) is a product development process that
assures the needs and desires of the customer are heard and heeded during the
design, development and production of a product. Though it has been ...
The Wiggins-Holmes extension of the generalized
Melnikov method (GMM) is applied to weakly damped
parametrically excited cross waves with surface tension in
a long rectangular wave channel in order to determine if
th ...
The objective of this research was to determine the feasibility of using chitosan
as a natural flocculant to control turbidity during in-stream construction work. A
series of field tests in Oak Creek, Corvallis, OR wer ...
Corrosion of reinforcement is recognized as the predominant factor that limits the service life of reinforced concrete (RC) structures exposed to aggressive environments. This corrosion deterioration can lead to damage r ...
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 ...
