为了研究考虑土和结构相互作用对Ⅱ类场地上的结构地震反应的影响，建立了三个不同输入形式的结构地震反应分析模型。通过三条地震波激励下，计算不同输入形式下结构的位移和内力反应峰值的变化，说明了不同土层特性对结构地震反应的影响。结果表明：Ⅱ类场地土土层中的结构抗震计算也应该考虑土和结构相互作用；土层剪切波速对结构响应的影响并无一致变化规律；覆盖层厚度越大，结构顶点位移和基底剪力随之增大；相同周期的土层上的结构响应并不一致。

In order to study the impact of soil-structure interaction on structural seismic response on the site typeⅡ, three different input forms of structural seismic analysis models are established.Under three seismic excita-tions, the changes of structural displacement and internal force peaks at different input forms are calculated, indica-ting the effect of different soil characteristics on the seismic response.The results showed that soil-structure interac-tion should be considered in structural seismic calculations on site typeⅡ;the impact of soil shear wave velocity on the structural response has no consistent variation;the structural top displacement and base shear increases with the thickness of the cover layer;the seismic response of the structure on the site with the same period is not consistent.
