Soil Structure Interaction of R.C. Building with Basement Resting on Pile Raft Foundation

Abstract

Abstract: Historically, Basements or underground stories were built in a castle to use as a dunged on oar store room. However, in modern construction, the restrain to go deeper below the grade level in term so basements which can be utilized for parking, shopping mall or combination of both. In such cases, dynamic soil properties have a significant effect of activating dynamic soil structure interaction phenomena on during earthquake. Here in present study an effort is made to study the behavior of a building by varying number so basements considering dynamic soil structure interaction. Issues like considering higher frequency modes, influence zone to be considered for dynamic soil structure interaction, behavior of building with basements under different water level conditions for two different types of layered soil and their comparison with fixed based structure is deal with. It is observed that dynamic soil structure interaction can significant change the behavior of the building and hence it is recommended to perform dynamic soil structure interaction for building with multiple basements. In addition, some important recommendations are provided at the end to serve as a guide for researchers and practicing engineers.
