Abstract: An averaging methodology is employed in studying dynamics of a two-degree-of-freedom nonlinear oscillator. The main system is modeled as a van der Pol oscillator under harmonic forcing. The ...

Abstract: A set of equations is derived describing the dynamic response of cylindrical liquid storage tanks under horizontal ground excitation. The structure consists of a flexible cylindrical tank with ...

Abstract: Two simplified models are presented for determining the hydrodynamic loads developed during the seismic response of tall unanchored liquid storage tanks. In both models the general procedure ...

Abstract: A general methodology is presented for investigating ride dynamics of large order vehicle models in a systematic and computationally efficient way. First, the equations of motion of representative ...

Abstract: An appropriate substructuring methodology is applied in order to study the dynamic response of very large scale mechanical systems. The emphasis is put on enabling a systematic study of dynamical ...

Abstract: A finite element model is presented for the seismic response of liquid-filled tanks. This type of analysis is complicated for unanchored tanks, because the bases of these tanks separate from ...

Abstract: An analysis developed for the response of liquid storage tanks under horizontal base excitation is employed and numerical results are obtained for unanchored tanks. These results are compared ...

Abstract: The dynamic response of a general class of continuous linear vibrating systems is analyzed which possess damping properties close to those resulting in classical (uncoupled) normal modes. First, ...

Abstract: An explanation is provided for the earthquake-induced damage observed at the top of liquid storage tanks. An analysis is developed and the results are compared with experimental work. The basic ...

Abstract: The stability properties of periodic steady state response of a nonlinear geared rotordynamic system are investigated. The nonlinearity arises because one support of the system includes a cavitated ...
