摘　　要：通过分析指出了等效刚度比对高位拱式转换层结构抗震性能的影响。等效侧向刚度比对结构的自振周期及上部结构的振型曲线影响不大,而对结构的绝对位移和层间位移角影响较大;等效侧向刚度比为0.8~1.2较合适。除此之外,还应使转换层本层的侧向刚度与转换层相邻上一层的侧向刚度比大于0.6。The effect of the equivalent stiffness ratio on seismic behavior of a high arch transfer floor structure is analyzed and interpreted.The equivalent stiffness ratio has a little impact on the natural periods of the whole structure and vibration modes of superstructure,but has an important impact on the absolute displacement and the displacement angle of stories for the structure.It is suitable to control the equivalent stiffness ratio from 0.8 to 1.2.In addition,the lateral stiffness ratio of between the transfer floor and the above adjacent floor must be more than 0.6.
