Investigation of the shear strength of steel fiber-reinforced concrete beams through a coupled analysis of crack kinematics and shear-resisting mechanisms

Key Points

• Shear strength demonstrates a significant improvement due to the incorporation of steel fibers, enhancing concrete durability.
• The analysis includes both crack kinematics and the mechanisms that contribute to shear resistance, revealing key interactions.
• Through a coupled analysis, the relationship between crack propagation and shear-resisting mechanisms was thoroughly assessed.
• Findings emphasize the potential use of steel fiber reinforcement in practical concrete applications for better performance.
