Zhang, K; Li, D; Shen, X; Hou, W; Li, Y and Xue, X (2023) Research on strengthening stone arch bridge with CFRP rebars. International Journal of Building Pathology and Adaptation, 41(5), pp. 1014-1028. ISSN 23984708
Abstract
Purpose: This paper aims to describe carbon fiber reinforced plastics (CFRP) bars as a way to strengthen a 40-year-old stone arch bridge. To investigate effectiveness of the strengthening method, fielding-load tests were carried out before and after strengthening. Design/methodology/approach: High-strength CFRP bars with minor radius, high tensile strain and good corrosion resistance were used in this reinforcement. The construction process for strengthening with CFRP bars – including CFRP bars cutting, crack grouting, original structural surface treatment, implant drilling, CFRP bars installation and pouring mortar – was described. Ultimate bearing capacity of the bridge after strengthening was discussed. Findings: The results of concrete stress and deflection show that the strength and stiffness of the strengthened bridge are improved. The strengthened way with CFRP bars is feasible and effective. Originality/value: This paper describes CFRP bars as a way to strengthen a 40-year-old stone arch bridge.
