Notes:
This paper presents an accurate algorithm for structural non-stationary random seismic responses. The ground acceleration is assumed to be an evolutionary random process, of which the modulation function is non-uniformly modulated, i.e. it depends on both time and frequency. The method is used to compute the non-stationary seismic responses of a non-uniform shear beam. The dependency of the power spectral densities of the excitations and of the responses on time and frequency is discussed, based on numerical results. ©1997 John Wiley & Sons, Ltd.
