The rapid development of urban infrastructure has led to the erection of tall buildings that are more and more susceptible to lateral forces due to wind. The study is on the structural performance of a thirty-storey reinforced concrete (G+30) building under the effect of wind loads. The study has been carried out for a bracing system and without a bracing system. The analysis was performed using ETABS structural design software according to IS 875 Part 3 wind load standards. Different bracing arrangements like X-bracing, K-bracing and Chevron bracing were studied to check their resistance against lateral displacement, storey drift and base shear. Wind loads were considered for different terrain categories and wind directions to provide realistic field conditions. The results indicate that unbraced structures experience much higher lateral displacement and inter-storey drift that adversely affect serviceability and occupant comfort. The most effective bracing type among the bracing types studied was X-bracing, which reduced the roof displacement and maximum storey drift by 29.3% and 37.8%, respectively, as compared to the unbraced model. Both K-bracing and Chevron bracing also performed significantly better, but with a little less efficiency. The findings demonstrate the significance of bracing systems for the safety and long-term durability of high-rise buildings when subjected to wind forces. The findings of the comparative study of the performance of bracing systems can assist the engineers and architects in choosing the appropriate lateral load-resisting systems. This study can also be considered in future investigations that consider combined wind and seismic loading scenarios for a more comprehensive structural assessment.
