A Study on Wind Load Analysis of High Rise Building using CFD

This research show the effects of external wind flow conditions on the high rise building’s stability having balconies and without balconies as well. It focuses on how corner treatment techniques of balconies and buildings such as flow spoilers, chamfering, and tapering wind-induced forces reduce the effects of uplift, shear, and lateral loads on the high rise buildings. Computational Fluid Dynamics (CFD) simulations were conducted on structure for this research by using ANSYS software for CAD modelling to analyze wind pressure, velocity profiles, and lateral deformation. After that static structural analysis was performed to evaluate shear stress and deformation produced under wind loads, according to IS 875 Part III standards. The study helps to reduce drag forces and improve structural integrity by the help of aerodynamic edge treatments without changing the structural parts of buildings. Providing chamfered and tapered designs of high rise building, the drag forces were reduced by up to 40% which helps to enhance the structural safety and performance. The flow spoilers and chamfering of corners in high rise structure reduce wind loads and optimize structural serviceability. Integrating aerodynamic considerations into high-rise building designs, particularly in regions prone to severe wind conditions will solve the challenges which arise due to wind vibrations and deformation, and provide long-term resilience and safety to structure. In conclusion, The research show attention to the practical implications of aerodynamic designs in modern structural engineering world by providing actionable insights into effective design strategies, wind-structure interaction and offering guidelines for architects and engineers. Using CFD helps to design advanced sustainable and efficient high-rise construction.
