| Abstract: | A stationary power spectral model presented by Hu Yuxian is selected as a random earthquake excitation for base-isolated structures.The story hysteretic drifts of the base-isolated structures are described by Bouc-Wen model.The equivalent linearized state equation is established after equivalent linearization of dynamic property matrixes of hysteretic system.By introducing left and right eigenvector series,the vibration differential equation is decoupled and the analytical solutions of response statistical ... |
