Settlement predictions for normally consolidated alluvial silt

Creator:: Rippe, Arlan H.
Abstract:: Settlement of structures built on geologically recent compressible alluvium is a common cause of concern during design. Total settlement results from a combination of: 1) initial elastic settlement, 2) primary consolidation, and 3) secondary compression. The reliability of prediction of total settlement is affected by an understanding of these components...

Finite element analysis of wave-structure interactions in the time domain

Creator:: Lee, Jaw-fang
Abstract:: The time-domain simulation of wave-structure interactions using the finite element method is presented in this study. Combined initial and boundary value problems for diffraction and radiation of waves by large structures are posed. Linearized free surface boundary conditions are used, but motions of the structural boundaries compared to the wave...

Behavior of gypsum-sheathed cold-formed steel wall stud panels

Creator:: Lee, Young-ki
Abstract:: 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 for Wall-Braced Wall Stud Columns. The purpose of Part A is to develop experimentally-based limiting heights...

Preparation and laboratory evaluation of stationary-phase iron-oxide-based adsorbents for removal of metals from waste waters

Creator:: May, Michael Lee
Abstract:: Several potential sorbent materials containing iron oxides were prepared and evaluated for potential to remove divalent metals from waste waters. These included a ferrihydrite-coated sand, maghemite incorporated in Dowex[Trademark] ion exchange resin, gothite and two thermally activated ferrihydrites. Attempts to prepare sorbents from steel shot by coating with ferrihydrite or...

The contribution of morphologic slope on wave, current, and combined wave-current driven sediment flux and ripple geometry on an idealized sand mound

Creator:: Lee, Seok-Bong
Abstract:: Sediment convergence and divergence zones create subaqueous morphological features that range from ripples O (cm) to coastlines O (km). However, there is a gap in knowledge associated with quantifying the contribution of small-scale ripple mobility to the evolution of large-scale morphology. To address this gap, we investigate how small-scale ripples...

Wave interaction with permeable structures

Creator:: Lee, Chung-pan
Abstract:: A theory is developed to provide an analytical solution to an unsteady flow field which is partially occupied by a porous structure. The flow is induced by a small amplitude incident wave train. The porous structure may contain multi-layer anisotropic but homogeneous media. Three typical porous structures are investigated: a...

Anaerobic reductive dechlorination of TCE and TCFE in TCE contaminated sediments : enhanced bioremediation and bioaugmentation

Creator:: Lee, Jae-Hyuk
Abstract:: This research focused on the enhanced reductive dechlorination of trichloroethene (TCE) and its surrogate, trichlorofluoroethene (TCFE), using two bioremediation methods in anaerobic conditions. Two anaerobic bioremediation studies were conducted to investigate the effects of microbial communities in the presence of different electron acceptors and donors during anaerobic reductive dechlorination of...

Experiments on cable strumming and flow induced drag

Creator:: Barnes, Bert Lee
Abstract:: Short non-flexible elements of cable were driven harmonically in water while constrained by springs. The cable elements were observed to oscillate at approximately the Strouhal vortex shedding frequency. Damped resonance occurred near the point where the natural frequency and the Strouhal vertex shedding frequency were equal. Transverse oscillation amplitudes greater...
