摘要

This study investigates the impact of basalt fiber on the mechanical properties of reinforced concrete members, with a specific focus on their behavior under large eccentric compression. A series of large eccentric compression tests were conducted on basalt fiber-reinforced concrete (BFRC) members with varying parameters. The failure characteristics, ultimate bearing capacity, cracking load, crack width, and other relevant factors were thoroughly analyzed. The results indicate that the mechanical properties of BFRC components are significantly improved compared to traditional concrete using basalt fiber reinforced concrete. Specifically, the ultimate bearing capacity increased by up to 30.3%, while the cracking load exhibit ed a notable increase of up to 42.9%. Notably, BFRC members displayed enhanced loading characteristics, including delayed crack initiation, a greater number of cracks, and a smaller maximum crack width. A comprehensive data simulation was performed, leading to the development of a calculation formula for the maximum crack width of BFRC members under large eccentric compression.
