Response statistics of monopile OWT to fully nonstationary seismic motion

The data shows the MATLAB file and the results in the numerical studies. The folder "MATLAB_2exponential" gives the computation of response EPS and mean square values of the monopile OWT under 2-exponential modulated Kanai-Tajimi seismic motion, by the proposed method and Monte Carlo simulations (Case 1 in the numerical studies). The folder "MATLAB_gamma" gives the computation of response EPS and mean square values of the monopile OWT under gamma modulated Kanai-Tajimi seismic motion, by the proposed method and Monte Carlo simulations (Case 2 in the numerical studies). The folder "MATLAB_gamma_prony" gives the computation of response EPS and mean square values of the monopile OWT under gamma modulated Kanai-Tajimi seismic motion, by the proposed method and Monte Carlo simulations, but the gamma model with non-integer coefficient (Case 3 in the numerical studies). The folder "MATLAB_fullynonstationary" gives the computation of response EPS and mean square values of the monopile OWT under fully nonstationary seimic motion, by the proposed method and Monte Carlo simulations (Case 4 in the numerical studies).
