This thesis is concerned with passive control systems for seismic protection of building structures, with special emphasis on elastomeric bearings, viscous dampers and tuned mass dampers. Both mathematical modeling and ...

Utilizing simplified structural and hydrodynamic models, a parametric study is performed comparing response predictions for the Cognac deepwater platform as it is subjected to wave-and-current forces. Comparisons for the ...

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 ...

An anisotropic critical state model for monotonic and cyclic loading of Ko-consolidated clay is presented, based on extension of an existing model. First, the performance of two existing critical state models is evaluated ...

A two-part study of the dynamic response to horizontal base shaking of vertical, rigid and flexible walls retaining a uniform soil stratum is presented. The first part deals with available pseudostatic, limit-state methods ...

Rice University's Department of Civil Engineering recently added an electro-hydraulic shaking table facility to their testing laboratory. The purpose of the shaking table is to evaluate the response of scaled model structures ...

A complete mathematical model of the Rice University shaking table facility is developed. The analytical model, developed on the basis of previous work, is then fully developed in order to account for: Proportional, Integral, ...

The purpose of this research was to compare hydraulic conductivity estimates in a bounded phreatic aquifer derived from slug tests to those calculated from more accurate and costly tracer tests. A slug test is a simple ...

The behavior of reinforced concrete beams under pure torsion was studied. Six reinforced concrete beams were designed with stirrup spacing as the principal variable and tested under monotonic loading up to failure. Loads, ...
