Soil is a multiphase material, which is not linearly elastic or perfectly plastic for external loading and soil behaves nonlinear during earthquake. During seismic design, foundation is assumed as fixed which does not response for dynamic evaluation. An evaluated structure for lateral forces using SAP2000 software and ATC-40 earthquake data has been used. The effect of soil structure interaction as per code for analysis procedure is complexity and the soil parameter is considered as springs and the elasticity is presented in the form of fundamental natural period of vibration and base shear of the structure. The structure is analysed the performance of the structure by nonlinear static analysis in SAP2000 software. The performance of the structure is evaluated under immediate occupancy, life safety and collapse prevention levels as defined as ATC-40 for the respective performance point of structure.
