A wavelet-based formulation has been presented in this paper for the stochastic analysis of a linear multi-degree-of-freedom (MDOF) classically damped system subjected to earthquake ground motion. The ground motion has been modelled as a non-stationary process (both in amplitude and frequency) using
## Abstract A method concerning the evaluation, in a very compact form, of the nonβstationary modal crossβcorrelation coefficients of MDOF structural systems subjected to seismic excitations is presented. It is available both in the case when the excitation is considered as a whiteβnoise process an
The exact stationary solutions of the averaged equations of stochastically and harmonically excited n-degree-of-freedom quasi-linear systems with m internal and/or external resonances are obtained as functions of both n independent amplitudes and m combinations of phase angles. To make the solutions
