Abstract :

The Influence Of Soil-structure Interaction In The Analysis And Design Of A Building With Base Isolation Of A 16-storey Reinforced Concrete Frame Building Is Investigated. The Inclusion Of The Soil In The Structural Analysis Provides Displacement Values, Which Are Closer To The Actual Behavior Of The Structure Than Those Provided By The Analysis Of A Fixed-base Structure. In Seismic Environment, The Loads Imposed On A Foundation From A Structure Under Seismic Excitation Can Greatly Exceed The Static Vertical Loads As Even Produce Uplift; In Addition, There Will Be Horizontal Forces And Possibly Movement At Foundation Level. The Soil And Rock At Site Have Specific Characteristics That Can Significantly Amplify The Incoming Earthquake Motions Travelling From The Earthquake Source There Is A Reduction Of Seismic Impact On The Structure By Base Isolation. Six Different Model Conditions Are Considered Namely Fixed-base And Rubber Base Behavior Are Considered. The Influence Of The Soil Structure Interaction In The Dynamic Behavior Of The Structure Is Reflected In An Increase In The Vibration Period As Well As Increase In The Drift Of The Superstructure Which Leads To Less Acceleration To The Structures. Keywords: Fixed-base Structure, Rubber Base Behavior, Vibration Period, Drift, Acceleration.
