Pile hammer selection by driving stress analysis

Creator:: Barrero-Quiroga, Franklin
Abstract:: This paper presents an application of the wave equation to the problem of selecting a driving hammer for prestressed concrete piles. The potentially damaging effects of these types of hammers on various prestressed concrete piles were analyzed by means of parametric studies carried out on a hypothetical group of problems...

Evaluation of selected marginal aggregates stabilized with cement

Creator:: Chang, Chen
Abstract:: Coastal Oregon is deficient in quality construction aggregate. There is, however, an abundance of lower quality, or marginal aggregate available for construction purposes. The purpose of this report is to develop techniques for upgrading marginal aggregates with portland cement and methods for evaluating the relative performance of these stabilized materials...

A kinetic approach for the determination of sorption rate constants using a column-type reactor

Creator:: Patrier, Lionel
Abstract:: A Langmuir sorption model incorporating a second step of irreversible absorption was applied to a model soil system. The column was packed with cellulose triacetate; pulse and step input tests with 3,4-dichlorophenol were performed; the effluent concentration was measured by electron capture detector gas chromatography and sorption rate constants were...

Aerobic cometabolism of chloroform by butane and propane grown microorganisms from the Hanford subsurface

Creator:: Kim, Young
Abstract:: Batch microcosm studies were carried out to screen for microorganisms from the subsurface of Hanford DOE site that could cometabolically transform chloroform (CF) under aerobic conditions. The potential need for CF bioremediation at the Hanford site has resulted from the large release of carbon tetrachloride (CT) to the subsurface, of...

Computerized safety analysis technique for secondary highways

Creator:: Nichols, Kevin Scott
Abstract:: Evaluation of the safety hazards along a highway is usually performed at specific locations and on known hazards. But, it is also important to find any unrecognized hazards and their locations. Many factors contribute to accident potential, and the combined effect of several of them could produce a hazard that...

Investigation of Drilled Shafts under Axial, Lateral, and Torsional Loading

Creator:: Li, Qiang
Abstract:: Drilled shaft foundations provide significant geotechnical resistance for support of structures, such as highway bridges, traffic sign, and signal pole structures, and are used widely to meet their structural foundation requirements. The amount of steel reinforcement in drilled shaft foundations has increased over the past several decades to account for...

Early age performance of latex-modified concrete bridge deck overlays

Creator:: Sujjavanich, Suvimol
Abstract:: Environmental factors and physical properties of latex modified concrete (LMC) are hypothesized to contribute to early age cracking in bridge deck overlays. Cracking permits the ingress of moisture and aggressive solutions into the substrate and may contribute to other subsequent distresses. Understanding the material properties and mechanisms involved is necessary...

Development of the simplified method to evaluate dynamic mechanical analysis data on asphalt-aggregate mixtures

Creator:: Ab-Wahab, Yunus Bin
Abstract:: Testing of asphalt binders and asphalt-aggregate mixtures using dynamic mechanical analysis is becoming popular with improvements in high-speed computers, precision equipment, and computer software. Researchers are trying to describe the behavior of asphalt binders and asphalt-aggregate mixtures in terms of their time- and temperature-dependent linear viscoelastic behavior. The objectives of...

Tsunami Loading on Coastal Infrastructure

Creator:: Xie, Zhongliang
Abstract:: The safety of coastal infrastructure has been a concern after the Indian Ocean Tsunami in 2004 and the Great East Japan Tsunami in 2011. The western coast of the United States is also exposed to tsunami hazards due to the Cascadia subduction zone. Therefore, it is critical to design coastal...
