<![CDATA[High-rise reinforced concrete (RC) buildings are highly vulnerable to seismic forces due to their inherent structural limitations, necessitating effective energy dissipation mechanisms. Conventional damping strategies often fail to adequately control excessive vibrations, leading to potential structural damage. Fluid Viscous Dampers (FVDs) offer a novel approach by significantly improving energy dissipation and reducing seismic responses. However, the optimal configuration, placement, and quantity of FVDs in high-rise buildings remain insufficiently explored, necessitating this study. This research introduces a novel damper placement framework by investigating the strategic positioning of FVDs in a 25-storey RC benchmark building, evaluating 80 damper configurations using non-linear time history analysis in ETABS. The study compares Strategic Location Formats (SLFs) against Arbitrary Location Formats (ALFs) and Uniformly Distributed Frames (UDFs) to determine the most effective and economical damper placement strategy. Findings reveal that SLFs achieve superior seismic performance while using significantly fewer dampers, demonstrating an innovative and cost-effective approach to structural damping. SLFs achieve up to 45% reduction in displacement, 56% reduction in inter-storey drift, and 54% reduction in base shear, using only 36 dampers, compared to 96 in ALFs and 192 in UDFs. Additionally, SLFs are highly cost-efficient, requiring only 9% of total construction costs, compared to 24% for ALFs and 49% for UDFs. This study establishes a novel, performance-based damper placement framework, offering a scientifically validated methodology for optimizing seismic resilience while maintaining economic feasibility. These findings make SLFs a transformative solution for high-rise RC buildings in earthquake-prone regions.]]>
