A Comparative Study Of An Outrigger Structural System Studied Under The Lateral Loading On Different Buildings Structural System. Obtained Analysis Reveals That Placing Outriggers At Specific Storeys Can Significantly Impact The Building’s Lateral Displacement And Stiffness Under Seismic And Wind Loads. The Study Offers Important New Perspectives On The Role That Outriggers Play In Improving The General Stability And Efficiency Of Elevated Structures Under Lateral Load Conditions. Analysis Of Lateral Displacement During Seismic And Wind Loads Shows That The Highest Possible Lateral Displacement For A Structure Without Outriggers Is Larger Compared To Buildings With Outriggers At Particular Heights, So Highlighting The Decrease In Lateral Displacement With Outrigues In Place. Investigation Into The Percentage Reduction In Lateral Displacement For Buildings With Concrete Outriggers At Different Heights Demonstrates Varying Levels Of Reduction, With Outriggers Positioned At Optimal Heights Showing The Highest Reduction In Lateral Displacement Under Lateral Loading Conditions. In This Research Work I Prepared Four Different Cases In ETABS Software. Outrigger Structural System Placed As A Reinforced Concrete Element At Different Locations In An Entire Building Of G+50 Stories. They Serve As A Fixed Base For The Building From That Particular Floor And Increase The Overall Stiffness Studied Under Response Spectrum Analysis.
