摘　　要：分析了高层塔式建筑各抗侧结构间的相互作用,建立了静力计算模型,用高阶微分方程组描述并解偶这种相互作用,推导了结构内力、位移表达式。经比较,所得侧移、层间剪力分配结果与有限元分析结果基本一致。该模型有助于在初设阶段对抗侧结构及其连接构件的布局合理性进行判断和调整,可为改进结构抗震设计提供依据。An analytical model for the preliminary seismic design of high-order buildings with multi-lateral structures is developed.A high-rank differential equation group is established,with which the reciprocal action among the lateral structures can be decoupled.Comparison is done between the calculated results of this model and another FEM model developed via ANSYS.The model and the suggested calculation method can be used to judge the reasonable structural layout in the stage of preliminary seismic design.
