Effect Of Column And Beam Geometry On The Seismic Behavior Of Multi-storey Reinforced Concrete Frames

Abstract

This Research Paper Investigates The Seismic Performance Of Multi-storey Building Frames With Varying Column And Beam Geometries Under Seismic Loads. A G+10 Storey Reinforced Concrete (RC) Building Frame Was Analyzed Using STAAD Pro V8i Software In Seismic Zone III With Medium Soil Conditions. Three Models (Plan A, Plan B, And Plan C) Were Considered, Each With Different Cross-sectional Dimensions For Columns And Beams (230×230 Mm, 300×300 Mm, And 380×380 Mm, Respectively). The Study Evaluated Key Structural Responses, Including Support Reactions, Bending Moments, Shear Forces, Axial Forces, And Displacements. Results Indicate That Increasing Member Dimensions Reduces Displacement And Axial Forces But Increases Bending Moments And Shear Forces. Plan C (380×380 Mm) Exhibited The Least Displacement, While Plan A (230×230 Mm) Showed The Highest. The Findings Highlight The Importance Of Optimizing Member Geometry For Seismic Resilience In Multi-storey Buildings
