Abstract

In the conventional technique of analysis flexibility of soil, mass is omitted which is in all likelihood to have an effect on the overall performance of the structure. In the proposed study a try is made to apprehend the effect of soil flexibility on the overall performance of building frames. As the traditional evaluation technique does not address the soil-structure interaction explicitly, the effect of soil-structue interaction on the reinforced concrete structure is studied using the response spectrum method. Three G+6 story building on three kinds of soil interaction are modeled and subjected to an earthquake. Buildings resting on a fixed base. Dynamic analysis is carried out by the use of the Response Spectra of IS: 1893-2002. Etabs 2016 is used for developing those models. The impact of SSI on diverse structural parameters i.e. Base shear, story shear, story displacement, story flow and overturning moment are studied and discussed. The study shows that the SSI significantly influences the reaction of the structure. The effects brought about a criterion indicating that considering SSI in seismic design, for buildings on medium and soft soil is essential.
