Results obtained by applying the method of stochastic averaging to random vibration
problems are discussed. This method is applicable to a variety of problems involving the …

The duration of strong ground shaking during earthquakes can play an important rôle in the
response of foundation materials and structures, particularly when strength or stiffness …

A procedure is developed for the simulation of artificial earthquake accelerograms, The time
variation of amplitude and frequency content is preserved in the simulation procedure …

Eight strong-motion accelerograms recorded on firm ground and at moderate epicentral
distances are studied for the purpose of developing a reasonable stochastic representation …

For systems driven by wide-band random excitation processes it is possible to model the
response as a multi-dimensional continuous Markov, or diffusion, process. This approach …

If earthquakes are modelled by a stochastic process, it is possible to interpret the associated
response spectrum in terms of the statistics of extreme values of oscillator response to the …

A classical problem of considerable practical importance is to determine the probability p 1
(T) dT that the absolute value of a random vibration surpasses a threshold for the first time …

First-passage problems for a lightly damped linear oscillator excited by white noise are
described for two types of initial conditions and three different types of barrier configurations …

abstract Though many models for the simulation of earthquake records have been
suggested, they are either unrealistic or restricted to a qualitative simulation. If the basic …

The generalized nonstationary Kanai–Tajimi model is used to describe and simulate the
ground motion time histories. Both amplitude and frequency nonstationarities are …
