Abstract

Abstract

Comparative test on the seismic performance of rectangular concrete columns strengthened with basalt fiber reinforced polymer(BFRP) and carbon fiber reinforced polymer(CFRP) was conducted.Test results show that basalt fiber tow winding retrofit technology can significantly improve the shear strength of the concrete columns and change the failure modes.Contrasting to the columns wrapped with CFRP,it is confirmed that with similar lateral confinement stiffness,the strength and ductility,energy absorbing and other structural performance of the columns wounded with BFRP could be achieved,while the price of BFRP is lower.It is worthy to be widely applied to strengthen engineering structures.
