High-rise structures, Wind engineering, Computational fluid dynamics, Vortex shedding, Aerodynamic optimization.Abstract
This study investigates the impact of wind forces on high-rise structures through comprehensive computational fluid dynamics (CFD) simulations and wind tunnel testing. The research evaluates five distinct building geometries subjected to varying wind conditions to determine optimal design strategies for mitigating structural vibrations and reducing wind-induced loads. Data collected from 47 high-rise buildings across three major urban centers reveals a significant correlation between building shape modifications and reduced wind pressure coefficients. The implementation of aerodynamic modifications, including chamfered corners, tapered profiles, and strategic setbacks, demonstrated a 24-38% reduction in peak wind loads. Statistical analysis of the collected data indicates that integrating computational predictions with physical testing provides the most reliable framework for high-rise wind design. This paper presents a systematic approach to wind-responsive design that balances structural integrity, occupant comfort, and energy efficiency considerations while adhering to international building codes. The findings offer valuable insights for architects and structural engineers developing resilient high-rise structures in regions prone to severe wind events.
