In the present study the dynamic behavior of light weight floor building frames under seismic forces uniting soil structure interaction is considered. The analysis is carried out using FEM software STAAD-Pro. In interaction analysis of space frame, soil are considered as parts of a single compatible unit and soil is idealized using the soil models for analysis. The soil system below a raft footing is replaced by providing a true soil model (continuum model). In continuum model, soil is considered as homogeneous, isotropic, elastic of half space for which dynamic shear modulus and Poisson’s ratio are the inputs. To estimate the Story drift, base shear and ground motion for earthquake zone IV and zone V structures considering situated in clayey and sandy soil To study the behavior of the building for ground motion displacement. To evaluate the various results by comparing normal concrete structure without SSI and normal concrete structure with clayey sand sandy soil structure interaction To evaluate the various results by comparing lightweight concrete structure without SSI and lightweight concrete structure with clayey sand sandy soil structure interaction.
