Abstract

Soil condition is an important research area in earthquake engineering. In this work we evaluated the impact of soil-structure interaction (SSI) and U-shaped steel damper on the isolated response of the building base. Different soils for a seismic performance of multistory buildings are systematically compared and discussed. The soil’s physical state is divided into; hard soil, medium soil, and soft soil. It was compared with the U-shaped steel damper and there is noticeable difference between them. This study concludes that the use of steel damper shaped and SSI has been effective in minimizing structural response. It was observed that interaction of the soil structure provides some flexibility to the structure by increasing the structure’s displacements. Modeling base isolation along with consideration of soil structure interaction therefore leads to better structural response prediction.
