Abstract

The response of the soil influences the motion of the structure and response of the structure changes the ground
motion history making the competition very complex and this phenomenon is known as Soil Structure
Interaction. Various field tests indicate that the Soil-Structure Interaction (SSI) has a very significant impact on
behaviour of structural elements of multi-storeyed buildings, which may lead to an unexpected structural
seismic responses and/or failure. In this study, a simple five storied structure with fixed support is modelled by
using ETAB. Numerical results obtained from analysis of fixed-base condition are compared with the results
obtained from flexible-base condition. It was observed that the flexibility of structure reduces the overall
stiffness and at the same time the natural period of the system were increases with considering the influence of
the Soil Structure interaction of the system. The presence of the soil in the structural analysis provides the result
of various parameters such as storey displacement, storey drift which are nearer to the actual dynamic behaviour
of the structure than those provided by the analysis of a fixed base structure.
