| Abstract: | In this paper, the random response and equivalent wind action of structures with nonlinear fluid viscous dampers subjected to Davenport random wind-induced model excitation were studied systematically. The nonlinear dynamic equations of structures were established. The complex model method was used to disconnect the equations after the equivalent linearization. The analitic solution of response random wind-induced response was obtained. |
