abstract = "This paper presents a mode-based equivalent method for seismic response analysis of soil column. The key to this method is the equivalence of modal properties between two linear systems. Four principles of mode equivalence are prescribed in terms of four modal properties which are independent of mode normalization. Based on this method, an equivalent Multi-Degree-Of-Freedom (MDOF) system is developed to idealize a soil column. Seismic response of the equivalent MDOF system is analytically derived through mode superposition method. The physical parameters of the equivalent MDOF system such as the mass, spring and damping constants, and the mass heights are formulated. The equivalent MDOF system is validated by comparing its seismic response with the solution of wave propagation. Results show that the proposed method can provide considerably accurate seismic response of soil column with few degrees of freedom.",
