| Abstract: | Considering the time spatial variability of earthquake ground motion, stationary and non stationary random processes are simulated by means of spectral representation method according to parameters of different site characters. Seismic response spectra of different sites are presented and compared with the spectra of Chinese Aseismic Design Code of Railway Engineering. This work is of importance for the research of aseismic design on different sites by way of response spectral method. |
