SPATIAL SEISMIC EXCITATIONS AND RESPONSE SPECTRA

ISET Journal of Earthquake Technology, 2007
Formal extensions of the response spectrum method to include spatial seismic effects are reviewed. Two approaches are described in detail: the first based on random vibrations of a simple oscillator under two-component excitations, and the second analyzing multi-column building seismic response.

Active vibration control of seismic excitation

Nonlinear Dynamics, 2017
Seismic wave control is very important both in civil and mechanical engineering. Common passive methods for isolating a building or a device include base isolators and tuned mass dampers. In the present paper, a time-varying controllable spring is considered as a vibration isolator for a linear mechanical system.

Structural Responses Due to Seismic Excitations

2014
The determination of the earthquake ground motions is an essential part of earthquake engineering. However, as the rate and duration of energy released from earthquakes is relatively random, it is not possible to obtain the exact excitation to which the structure will be subjected.

On the excitation of the earth's seismic normal modes

pure and applied geophysics, 1976
The excitation of the earth's normal modes is formulated as an initial value problem. The static state of the earth, stressed from its hydrostatic reference situation, is considered as the initial state. The initial state is relaxed, at the time of the earthquake, by the removal of the forces maintaining the departure from hydrostatic equilibrium ...
