New small-diameter CFRP material for flexural strengthening of steel bridge girders
Highlights Small-diameter CFRP strands strengthening system eliminate de-bonding failure. CFRP strengthening achieves failure due to crushing of the concrete. The proposed strengthening may be used to reduce deflection of members. The proposed system is effective for cyclic and fatigue loadings conditions.
Abstract This paper presents the research findings of an experimental program undertaken to examine the effectiveness of using small-diameter CFRP strands to increase the flexural capacity of steel beams and bridge girders. The experimental program included scaled steel-concrete composite beams, strengthened with these small-diameter strands. The CFRP strands were stitched together with a gap between the strands to allow the adhesive to penetrate and cover the entire perimeter of each strand. Results showed that the proposed system eliminated failure due to de-bonding of the strengthening materials and significantly increased the flexural capacity and stiffness of steel beams.
