| Abstract: | In this paper, the authors analyze the random critical seismic response of the Soil--SDOF nonlinear interaction system using the equivalent linearization method. As a numerical example,.the authors analyze the random critical seismic response of a water tower structure. By comparision with the response of the structure under the stationary filter white noise excitation, the method of random critical seismic response analysis is evaluated. |
