STUDIES OF DYNAMIC RESPONSE OF LIQUID STORAGE TANKS (FOUNDATIONS, RINGS, VIBRATION, DISCS)
This dissertation consists of four parts. The first part deals with the response of liquid storage tanks to a vertical component of ground motion. Galerkin's method is used to solve this problem approximately, and its ...
Dynamic response of force-excited systems
The elastic and inelastic responses of the force-excited single-degree-of-freedom (SDOF) systems are investigated from the gross characteristics of forcing functions such as the frequency content, the integrals and the ...
Nonnormality in the seismic response of primary-secondary systems
Response nonnormality is investigated for a yielding primary structure and a linear secondary system (P-S) subjected to a normally distributed ground acceleration. The nonlinearity considered is bilinear hysteretic (BLH) ...
Soil-structure interaction effects of simple structures supported on rectangular foundations
This thesis deals with the effects of soil-structure interaction, both kinematic and inertial, on the responses of seismically excited rectangular foundations and simple structures supported on such foundations. The ground ...
Evaluation of fuel ethanol releases in a pilot-scale aquifer tank: Source dynamics, NAPL migration and microbial community response
Ethanol is playing a key role in current discussions on energy, agriculture, taxes and the environment. This work addresses the potential environmental impacts and behavior of subsurface fuel-ethanol releases. A continuous-flow ...
Dynamic response of hazardous liquid-waste storage tanks used in nuclear facilities
This dissertation presents a comprehensive study of the dynamic response of storage tanks containing high-level radioactive wastes in nuclear facilities. Of the many issues that are peculiar to these systems, four important ...
Settling characteristics of fractal aggregates
The settling velocity of aggregates found in engineered water and wastewater treatment facilities are usually assumed to follow Stokes' law. These particles, however, are typically porous and may be fractal in nature. As ...
Effect of recirculation on the performance of a trickling filter
Abstract Not Available.
Bacteria and fullerene: The microbial response to fullerene water suspensions
The current nanotechnology boom necessitates timely research into the health and environmental impacts of nanomaterials to enhance their eco-responsible manufacture, use, and disposal. Using the water-insoluble C60 as a ...
Multi-Failure Mode Risk Assessment of the Houston/Galveston Bridge System to Hurricane Threats
This research implements the first Houston/Galveston area hurricane risk assessment of bridges for multiple failure modes: bridge deck uplift and bridge scour. Due to recent hurricane damage of bridges, emergency managers ...
