为了研究不同钢板加固方式对锈蚀钢筋混凝土梁承载性能的影响，探索不同钢板加固方式的加固效果，通过静力荷载试验对比研究了钢板抗弯加固、抗剪加固和抗弯抗剪组合加固锈蚀RC梁在承载力、变形、破坏模式和延性等方面的特点，分析了不同加固方式的优缺点。研究结果表明：组合加固效果最明显，其极限承载力比锈蚀梁提高了107.7%；对于抗弯加固锈蚀梁，钢板厚度分别为3、4、5 mm时，厚度每增加1 mm，其极限承载力增加7~18 kN；组合加固锈蚀梁的抗变形能力最强，其次是抗弯加固锈蚀梁，且钢板厚度增加对抗弯加固锈蚀梁的抗变形能力有积极作用；组合加固较其他两种加固方式能更有效地提高锈蚀梁的延性，其延性相比锈蚀梁提高了320.4%，其次是抗剪加固锈蚀梁；抗弯加固锈蚀梁的延性比其他两种加固梁小，且随着钢板厚度增加，其延性先增加后减小。评价抗弯和抗剪加固锈蚀梁的加固效果时，需综合考虑抗变形能力和延性。
In order to explore the influence of different steel plate strengthening methods on the bearing capacity of corroded RC beams, the strengthening effect of different strengthening schemes is explored. The characteristics in the bearing capacity, deformation, failure mode and ductility of corroded RC beams strengthening by steel plate with flexural strengthening schemes, shear strengthening scheme, and flexure-shear combination strengthening scheme are compared, respectively, and the advantages and disadvantages of different strengthening schemes are analyzed. The results show that for the flexure-strengthened corroded beam which steel plate thickness are 3 mm, 4 mm and 5 mm, respectively, the ultimate bearing capacity increased by 7~18 kN with 1 mm increases of steel plate thickness. The effect of combined strengthening is most significant, and the ultimate bearing capacity increased by 107.7% compared with corroded beams. Combined strengthened corroded beams have the strongest deformation resistance, the following is flexure-strengthened corroded beams, and the increases of steel plate thickness has a positive effect on the deformation resistance of flexure-strengthened corroded beam. The combined strengthening scheme is more effective in improving the ductility of corroded beam than the other two strengthening schemes, the ductility of which is improved by 320.4% compared with corroded beam, followed by shear strengthened corroded beams. The ductility of flexure-strengthened corroded beam is smaller than other two kinds of strengthened beams, and it increases in the begining and then decreases with the increases of steel plate thickness. The deformation resistance and ductility should be considered comprehensively when evaluating the strengthening effect of flexural and shear-strengthened corroded beams.
