STRUCTURAL PERFORMANCE EVALUATION OF BASALT FIBER-REINFORCED CONCRETE BEAMS AND BEAM-COLUMN JOINTS: AN EXPERMENTAL INVESTIGATION

Abstract

This study presents an experimental investigation into the structural behavior of basalt fiber-reinforced concrete (BFRC) beams and beam-column joints under cyclic loading conditions. 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).
