• Abstract:

  The Purpose Of This Research Study Was To Evaluate The Seismic Performance Of A High-rise G+20 RCC Structure, With An Emphasis On The Effectiveness Of Structural Upgrades Using Outrigger And Belt Truss Systems. The Outrigger And Belt Truss Model Systems, On The Other Hand, Demonstrated A Significant Decrease In Displacement And Drift. The Combined Outrigger And Belt Truss Model Fared The Best, Reducing Top-storey Displacement By Roughly 50% And Significantly Improving Base Shear Resistance. The Storey Drift Results Revealed That Inter-storey Deformation Was Most Apparent In The Conventional Model's Mid-levels, Possibly Causing Severe Levels Of Structural Instability And Damage To Non-structural Features Such As Walls And Facades. The Incorporation Of Structural Systems Brought Drift Values Well Below Allowed Limits, Resulting In Increased Structural Safety And Performance During Seismic Events. The Base Shear Analysis Revealed A Considerable Improvement In The Building's Ability To Bear Horizontal Forces Using The Upgraded Models. The Combined System Model Has The Greatest Base Shear Values, Emphasising The Importance Of Extra Lateral Stiffness In High-rise Buildings. This Shows That Buildings Using Outrigger And Belt Truss Systems May Better Absorb And Disperse Energy Under Dynamic Loads, Such As Earthquakes And Wind Forces, While Maintaining Structural Integrity. The Study Of Natural Time Periods And Frequency Responses Demonstrated The Structure's Better Dynamic Behaviour. The Natural Time Period Was Reduced With The Addition Of Structural Systems, Showing Increased Stiffness And Quicker Structural Reaction. Overall, This Study Demonstrates The Importance Of Including Outrigger And Belt Truss Systems Into The Design Of High-rise Structures In Order To Enhance Their Seismic Performance. These Systems Not Only Decrease Lateral Displacements And Inter-storey Drift, But Also Improve Load Redistribution, Resulting In Increased Stability And Less Damage From Seismic Loads. Findings Provide A Good Platform For Formulating Design Standards For Tall Buildings In Seismically Prone Locations.
