【Abstract】 A series-parallel-connection model with considering the influence of rotation nodes is developed in this paper. The coupling of horizontal and vertical displacement and the rotational displacement are eliminated using static condensation method. The frequency of free vibration, which couples with the horizontal and vertical vibration, is also given. The structure dynamic response subjected to both horizontal and vertical seismic excitation is obtained by using step by step integral method, which is of benefit to further research of the field.更多还原
