通过10根外部粘钢加固钢筋混凝土梁的斜截面抗剪试验,研究了外贴U型钢板、梁侧竖直钢板、梁侧斜钢板和梁侧钢丝网对梁的加固效果.试验结果表明:梁侧钢板角度对粘钢加固效果有明显的影响,采用45°斜向粘钢效果最好;由于锚固长度较短,易产生锚固破坏,应用时必须采取可靠的附加锚固措施;外部粘贴钢丝网无论是对提高抗裂能力还是承载能力都有明显的效果.通过理论分析,提出了粘钢加固梁斜截面的抗剪计算公式,与试验值吻合较好. The reinforcement effects of the U-shaped steel plate, the vertical steel plate on the beam side, the oblique steel plate on the beam side and the steel mesh on the beam side were studied by the oblique shear test of ten external steel-bonded reinforced concrete beams. The experimental results show that: Beam angle of the steel plate has a significant effect on the steel reinforcement effect, the best use of 45 ° bias steel sticking; due to the short anchor length, easy to produce anchor damage, the application must take reliable additional anchoring measures; external paste steel mesh Both the crack resistance and the bearing capacity have obvious effects.According to the theoretical analysis, the formula of the shear resistance of the inclined section of the bonded steel beam is proposed, which is in good agreement with the experimental data.
