Abstract :

Reinforced Concrete (RCC) Framed Buildings Are Among The Most Commonly Adopted Structural Systems For Residential Construction Due To Their Durability, Strength, And Adaptability To Varying Architectural Requirements. This Paper Presents The Three-dimensional Structural Analysis And Seismic Validation Of A G+2 Reinforced Concrete Residential Building Using STAAD.Pro V8i (SELECTseries 5). The Building Is Modelled As A Three-dimensional Space Frame Consisting Of Reinforced Concrete Beams, Columns And Slab Elements With Fixed Supports At The Foundation Level And Rigid Floor Diaphragm Action At Each Storey. The Model Represents A Typical Low-rise Residential Structure With A Total Height Of 9 M, Comprising 94 Joints, 110 Frame Members And 48 Shell Elements. M25 Grade Concrete And Fe415 Reinforcement Steel Are Considered For The Analysis.The Structure Is Subjected To Gravity Loads, Live Loads, Wind Loads And Earthquake Loads As Per The Provisions Of IS 875 And IS 1893. Equivalent Static Seismic Analysis Is Performed Considering Seismic Zone V Conditions, Medium Soil Type, An Importance Factor Of 1.0 And Response Reduction Factor Of 5. The Critical Load Combinations Generated In STAAD.Pro Are Analysed To Obtain Seismic Parameters, Nodal Displacements, Storey Drifts, Support Reactions, Beam Moments, Shear Forces And Column Forces. Results Indicate That The Estimated Seismic Weight Of The Building Is Approximately 2880 KN With A Design Base Shear Of About 259 KN. The Maximum Roof Displacement Under Seismic Loading Is Observed As 6.9 Mm In The X-direction And 6.1 Mm In The Z-direction, Which Is Well Within The Permissible Serviceability Limit. The Maximum Storey Drift Ratio Obtained Is Approximately 0.087%, Significantly Lower Than The IS 1893 Allowable Limit Of 0.4%.The Member Force Evaluation Shows That The Maximum Beam Bending Moment Is Approximately 51.3 KN·m And The Maximum Column Axial Force Is About 824 KN, Both Occurring Under Gravity Load Combinations. Code-based Comparison With IS 456, IS 1893 And IS 13920 Provisions Confirms That All Major Structural Parameters Remain Within Permissible Limits. The Study Demonstrates The Effectiveness Of STAAD.Pro V8i As A Reliable Platform For Threedimensional Modelling, Seismic Assessment And Performance Validation Of Low-rise Reinforced Concrete Framed Buildings.
