Abstract

Abstract

Basalt fiber is expected to be widely applied in civil engineering for its fine mechanic performance,good stability and comparatively low price.However,there is still little research in the aspect concerning with the application of basalt fiber in civil Engineering.Comparative test on the seismic performance of circular concrete column strengthened with basalt fiber reinforced polymer(BFRP) and carbon fiber reinforced polymer(CFRP) was conducted.The influence of fiber type and fiber amount on the strengthening effect was discussed.Test results show that BFRP and CFRP can both obviously improve the seismic performance of circular concrete columns,and more,BFRP has higher ratio of performance to price.
