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 ...

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 ...

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 ...

Fatigue damage due to random stress histories is typically estimated by either Rainflow range counting (a time history approach), or by the Rayleigh approximation (a power spectral density approach). These methods are not ...

This study is concerned with the prestressing of rolled sections by means of a tendon which at various points throughout its length is restrained from moving relative to the cross section but is free to move through the ...

Rotary drilling with roller cone bit is often accompanied by wide fluctuations of the weight on bit (WOB). In certain cases the WOB periodically reduces to null. It has been postulated that in these cases the bit lifts off ...

In this thesis, numerical data is presented for the natural frequencies of vibrations of rectangular plates of uniform thickness having all possible combinations of simply supported, fixed and free edges. A vide range of ...

The accuracy of five finite difference methods when applied to the analysis of plates of variable thickness is 'studied in this thesis. The plates are rectangular with two opposite edges simply supported. The thickness ...

An analytical closed-form solution has been developed for steady-state lateral response of concrete-face rockfill dams built in rectangular canyons. The canyon is assumed to be rigid, while the dam is idealized as a ...

The present study focuses on the estimation of the modal properties, i.e., natural modal frequencies, modal damping ratios, and mode shapes, of a structural system under ambient vibration based on the response data of the ...
