Abstract: The growing need for tall buildings in urban settings calls for efficient methods to reduce structural loads and vibrations caused by wind. This optimization, and sophisticated simulation techniques to summarize recent research on wind load reduction strategies. The most effective corner modifications, according to Computational Fluid Dynamics (CFD) studies, are rounded corners (10-20% reduction), but corner modifications like chamfering, rounding, and recessing can reduce wind loads by up to 30%. Comparative studies of building shapes show that non-traditional designs, such as fish-plan shapes, have lower drag and lift forces, while circular and tapered configurations perform better aerodynamically. Trade-offs between accuracy and cost are highlighted by wind tunnel experiments, such as High-Frequency Force Balance (HFFB) and High-Frequency Pressure Integration (HFPI) techniques, with HFPI offering more precise pressure distributions. A machine that is emerging Rapid urban population growth and rising need for high-density development have driven the building of ever more tall and thin structures. Although these buildings solve space limits, their increased sensitivity to dynamic loads and wind-induced vibrations creates major engineering problems. Focusing on three main areas aerodynamic changes, building shape optimization, and advanced computational techniques this thorough review paper methodically assesses modern research on wind load reduction strategies for tall structures Recent studies using Computational Fluid Dynamics (CFD) show that corner changes are effective; rounded (10-20% corner radius reduction) and chamfered edges lower wind pressures by 25-30% when compared to sharp-edged equivalents. Though they might increase vortex shedding effects at certain locations, tapered building profiles appear especially promising as they show 15-20% lower along-wind forces than prismatic shapes.
