Abstract :
    Soil – structure interaction is one of the most important topics in structural analysis and design . Influence of the soil – structure interaction is very important for the tall building on any soil and short structure on the soft / loose soils . Numerical method such as the FEM and FDM and general or specific softwares can be used to analysis the soil – structure interaction with high accurate and rate . Intermediate concrete frame on the soil type III ( based on iranian earthquake standard code ) assessment in this article . Analysis and design of structure perfomed by the softwares without the soil – structure consideration and then performed the perfect analysis by numerical method and finite element soft ware PLAXIS 3D FOUNDATION . The results showed clearly that the lateral displacement incresed but the column forces reduced for the case of soil – structure interaction . So suggested that performed this analysis for the important and special projects.
