Soil-Structure Interaction Effects by Different Soil on Seismic Response of Multi-Story Building on Raft Foundation
Abstract:
The soil flexibility effect is generally not considered in seismic design of building frames and the design is done based on results of dynamic analysis taking fixed base condition. In the present study the dynamic behaviour of building frames over raft footing under seismic forces uniting soil structure interaction is considered. For the interaction analysis of space frame, foundation and soil are considered as parts of a single compatible unit .Influence of number of parameters such as number of storey?s, soil types for seismic zone-V is considered in present study. Building responses are considered for bare frame with and without accounting for soil flexibility. The responses in terms of lateral natural period and seismic base shear, lateral displacement (story drift), with and without soil flexibility is compared to evaluate the contribution of soil flexibility on building frames.
