Development of stochastic quadratization for nonlinear systems with application to compliant offshore structures
The exploration and production of oil at offshore locations is extending into ever increasing water depths. To exploit this resource in water depths in excess of 300 meters, a new class of offshore structures called compliant ...
Random vibration of simple models for reinforced concrete structures
The dynamic response of stiffness degrading models subjected to random excitations is investigated. Monte Carlo simulation is performed to determine the effect on the response of various system parameters and to provide ...
Representation and synthesis of random fields: ARMA, Galerkin, and wavelet procedures
The dissertation considers methods of representation and synthesis of random fields and examines variance reduction techniques in conjunction with reliability analysis of engineering systems. The dissertation presents new ...
Deterministic and random vibrations of systems with frequency-dependent parameters or fractional derivatives
Frequency and time domain analyses of system models containing frequency dependent parameters or fractional derivatives are considered. Both model types result in integro-differential equations in the time domain, and in ...
Nonconservative control design for robustly stable structural dynamic systems
This dissertation considers a general concept of nonconservative measures of dynamic system performance via a consistent approach in terms of signal and system norms and suggests an appropriate iterative procedure for ...
Experimental investigation for constitutive modeling of fine sand under cyclic loading using hollow cylinder specimens
An experimental program for the understanding of the behavior of fine cohesionless soil under monotonic and cyclic loading and for the development and refinement of constitutive models has been undertaken. An experimental ...
