Seismic Analysis Of Base Isolated Building Under Near Field And Far Field Earthquake

This Work Presents A Thorough Seismic Investigation Of A Base-Isolated Structure Sensitive To Both Near-Field And Far-Field Seismic Events. The Aim Of The Research Is To Find How Effectively Base Isolation Techniques Increase The Seismic Resilience Of A Structure And Lower Its Response Under Different Seismic Environments. Using Complex Computational Techniques, An Ordinary Structure With A Base Isolation System Is Analyzed, Considering Realistic Material Attributes, Geometrical Designs, And Boundary Situations. Gathering And Analyzing Ground Motion Data That Represents Near-Field And Far-Field Seismic Conditions Allows Us To Replicate The Dynamic Excitations That A Structure Could Face. Nonlinear Dynamic Analysis Allows One To Evaluate The Structural Reaction Including Accelerations, Displacements, Inter-Storey Drifts, And Ground Response Spectra. The Effectiveness Of The Base Isolation System In Reducing Transmission Loads And Displacements Is Found And Compared Over Near-Field And Far-Field Earthquakes. Research On The Ease And Security Of The People Living In The Structure As Well As The Influence Of Significant Elements Including Structural Elements And Isolator Characteristics Also Take Place. The Aim Of The Work Is To Provide Analytical Data On The Seismic Response Of Base-Isolated Structures Under Different Seismic Conditions So Improving Methods Of Design And The Resilience Of Structures In Areas Prone To Earthquakes. In This Research Work Prepare Four Different Cases In ETABS. Base Isolation Devices Are Typically Installed Between A Building’s Foundation And Superstructure. They Serve As A Flexible Interface, Depending, In The Case Of A Seismic Event, On The Structure’s Ability To Move Regardless Of Its Position On The Ground Itself.
