Research on 1:4 Steel Frame about Soil and Structure Interaction

In the conventional structure’s calculation and design, the rigid foundation assumption was often used in calculation of the dynamic properties and dynamic responses, while the actual situation is often very different. In this article, a steel frame model on the scale of 1/4 on the soil bin (no cover) indoor was excited to achieve the responses of structures with different stiffness. The responses were compared between the actual structure and the rigid foundation soil assumption structure simulated in the SAP2000 software. The results show that the stiffness of the upper structure has great effect on the acceleration, displacement and natural period of the structure when considering SSI.
