The research aims to explore the mechanical enhancements provided by basalt fibers, particularly in improving tensile strength, ductility, crack resistance, and overall load-bearing capacity. Basalt fibers with a diameter of 30 ?m and a length of 25 mm were incorporated at optimal volume fractions of 0.250 % within the concrete matrix. The study examines the effect of the fiber content, fiber orientation, and mix properties on the mechanical properties of BFRC. The results indicate a significant improvement in the flexural and impact resistance, suggesting its suitability for structural applications. The investigations further extend to beam-column joints, demonstrating enhanced seismic resilience, stiffness, and energy dissipation. The findings highlight the potential of BFRC as a sustainable and durable material for modern construction, particularly in seismic-prone regions. © 2025 The Author(s).basalt fiberbeambeam-column jointseismic resistancestructural performance
