Prediction of fatigue life in relation to surface finish parameters
One can safely claim that not one single surface roughness parameter, in terms of completely characterizing a surface, can be exhaustive. This study is both an experimental and theoretical study of characterizing surface ...
Mixed finite element methods for variably saturated subsurface flow
The flow of water through variably saturated subsurface media is commonly modeled by Richards' equation, a nonlinear and possibly degenerate partial differential equation. Due to the nonlinearities, this equation is difficult ...
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 ...
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) ...
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 ...
Effect of recirculation on the performance of a trickling filter
Abstract Not Available.
Dynamic soil pressures on deeply embedded structures
The studies reported herein are motivated by the need to gain improved understanding of the response to earthquakes of deeply embedded and underground cylindrical tanks storing nuclear wastes, and develop rational but ...
