• Abstract:

  This Study Investigates The Influence Of Building Height, Seismic Zones, And Soil Types On The Structural Behavior Of Building Frames, Focusing On Maximum Node Displacement, Shear Forces, And Bending Moments. The Analysis Reveals That As The Building Height Increases, The Maximum Node Displacements And Beam End Forces (shear And Bending Moment) Also Increase, Particularly In Soft And Medium Soil Strata. Across Seismic Zones II, III, And IV, The Percentage Variation In Maximum Node Displacements Remains Nearly Consistent, With Hard Soil Strata Exhibiting The Least Displacements Compared To Soft Soil. Notably, In Seismic Zone IV (Model-3), No Significant Variation In Node Displacement Was Observed Across Different Soil Types. Similarly, Shear Forces And Bending Moments Decrease In Hard Soil Compared To Soft Soil, With The Lowest Values Recorded In Hard Strata For Seismic Zones II, III, And IV. However, In Seismic Zone IV (Model-3), Both Shear Forces And Bending Moments Remain Unaffected By Soil Type. The Findings Highlight The Critical Role Of Soil-structure Interaction In Seismic Performance, Emphasizing That Hard Soil Conditions Generally Lead To Reduced Structural Responses. These Insights Can Aid In Optimizing Seismic Design Strategies For Multi-story Buildings In Varying Seismic Zones.
