The simultaneous effects of soil and existing structures are known as the site-city interaction (structure-soil-structure). The impact of site-city interaction on structure behavior is effective. Thus, this interaction in some regions decreases the responses while increases in other areas. In addition, the site-city interaction of many parameters including the soil type, density rate, height of buildings is effective for evaluation. So far, none of investigation has focused on the effects of nature and shape of seismic wave and the plate which affects these waves in site-city interaction in three dimensions. Thus, the present study aimed to consider the effect of parameters mentioned in structure and foundation responses. The results indicated that the highest reduction for Love wave occurs in acceleration responses of structure in the cluster relative to the individual state, compared to the rest of the waves. Therefore, the reduction is about 30 and 50% for the base and top nodes of structures, respectively.
