Abstract

Soil-foundation-structure interaction can affect the seismic response. This work will study the effects of soil-foundation-structure interaction on the seismic response. Four types of foundations with frequency-based design were analysed, including spread foundation, mono pile, pile group with cap, and combined foundation. Soil is modelled both implicitly (subgrade reaction modulus) and explicitly. The finite element method using the Staad Pro program was first validated using experimental data. Recommendations were given to simplify the soil- foundation structure interaction analysis of seismic loading. In this research work we are comparing different shaped footing for same loading condition also soil bearing capacity to determine the best suitable and stale type of footing which can transfer load and also we are preparing cost analysis of all to determine the economical section using analysis tool staad.pro. In this study is can be concluded that Combined footing is comparatively more suitable and best in comparison with Oval or other cases whereas Oval footing is second best and Pad footing is showing worst result. The parameters used for analysis are selected such that they resemble the actual conditions. From the analysis, the method which gives the minimum ultimate bearing capacity for shallow foundation on top of the slope may be recommended for further design.
