Effects Of Wind Load On Hexagonal High-rise Building Having Different Corner Modifications

Abstract

This Project Investigates The Impact Of Wind Loads On Hexagonal-shaped High-rise Buildings Using Computational Fluid Dynamics (CFD). With The Growing Trend Of Complex Building Geometries And The Limitations Of Existing Wind Load Standards, The Study Compares Three Structural Forms: A Regular Hexagon, And Hexagonal Structures With Fillet And Chamfered Corners. Using CFD Analysis In ANSYS CFX (k-ε Model), Wind Effects Are Examined At Angles From 0° To 75° In 15° Intervals. Key Parameters Analysed Include Force Coefficients, Drag And Lift Coefficients And Moment Coefficients. The Results Show That Chamfered Corners Experience Significantly Higher Wind-induced Forces And Turbulence, Highlighting The Importance Of Design Modifications To Improve Structural Performance. The Study Emphasises CFD’s Role As A Cost-effective Alternative To Wind Tunnel Testing And Provides Valuable Insights Into Optimising Corner Configurations In Tall Hexagonal Buildings, Based On IS 875-3-2015 Standards.
