Dynamic Respone of RCC High Rise Building for Different Types of Sub-structure System

Abstract

This research work focuses on comparison of seismic analysis of G+15 building stiffened with soil interaction.. The performance of the building is analysed in Zone IV. The study include soil interaction for three different soil hard ,medium ,soft by fixed conventional method, FEMA 356, Wrinkler spring analysis. The study is extended for isolated footing and raft foundation . The analysed structure symmetrical,G+15,ordinary RC moment-resisting frame(OMRF). Modellimg of the structure is done as per Staad pro.V8i software. The lateral seismic forces of RC frame is carried out using dynamic static method as per IS 1893:2016 for earthquake zone. The scope of present work is to understand that the structure need to have suitable earthquake resisting features for different soil conditions. The result of the performance and the analysis of the model are the graphically represented and also in a tabular form and is compared for determining the best performance of building against lateral stiffness by arrangement of three different types of soil. A comparative analysis is done in term of base shear, displacement.
