Each building was supported on soft clay, stiff clay and very stiff clay with shear wave velocity of 100 m/s, 300 m/s and 600 m/s respectively. From this study it was found that there was no significant variation of natural period due to variation of stiffness of foundation soil. However, past research works showed that there is significant variation of natural period in similar cases. This is because of using same foundation sizes for different types of soil. Lateral deflection and base shear decreased with the increase of stiffness of foundation soil. Drift ratio and percent base shear decreases with the increase of number of story for same soil condition. The most important conclusion is that there is no significant variation of lateral deflection and base shear for same building and soil condition if soil structure interaction is considered. This means that if response spectrum for different soil types given in BNBC (2014) is used and foundation design is done properly, reasonably accurate result of analysis can be found without considering soil-structure interaction.
