【Abstract】 In this paper,soil and structure are taken into a joint dynamic system. By considering the multi-degree-of-freedom hysteretic property of structure and using the linearization technique and the state vector method, the statistical moments of the random responses of the soil and structure under earthquake are derived. Then an analysis method is presented for the random dissipative energy of the viscous damping and hysteresis of the soil and structure. Finally, a computational example is given in order to show the validity of the method presented in the paper.更多还原
