Nonlinear analysis of a structure loaded by a stochastic excitation

For a non-linear system excited by a stochastic load which is expressed as a time series, a recursive method based on the Z-transform is presented： To identify the obtained response time series, a discrete wavelet transform （DWT） technique is proposed.
