Abstract: The application of high-performance fiber-reinforced concrete (HPFRC) in tall building construction is explored in this study to evaluate its mechanical, durability, and seismic performance advantages over conventional high-strength concrete (HSC). The research focuses on the development and evaluation of HPFRC for structural elements such as shear walls, coupling beams, and core columns. Experimental tests on mechanical properties, including compressive and tensile strength, elastic modulus, and durability metrics (e.g., chloride penetration, freeze-thaw resistance, and sorptivity), showed significant improvements with HPFRC compared to control HSC. The cyclic performance of HPFRC coupling beams under simulated seismic loading conditions revealed superior energy dissipation and slower stiffness degradation. Numerical simulations validated these findings, predicting enhanced drift capacity and resilience under lateral loads. The results indicate that HPFRC offers enhanced strength, toughness, and durability, making it a promising material for tall building applications. Practical recommendations for its use in structural design and construction include optimization of fiber volume fraction (Vf) for cost-effective performance, integration into critical structural elements, and further research into mix design and quality control standards for large-scale implementation.
