本文以加固工程实践为背景,用有限元方法分析了对钢筋混凝土框架梁、柱构件交接点进行外粘钢板、粘结刚性支托加固后的应力分布,研究了梁侧粘贴不同宽度钢板的加固效果,分析表明:粘结刚性支托对结点处混凝土中最大拉应力影响相当明显。计算结果与现场实测应力相符。还研究了梁侧粘钢板的锚固长度问题,给出了相应的锚固长度公式。 In this paper, based on the reinforcement engineering practice, the finite element method is used to analyze the stress distribution of reinforced concrete frame beams and column members at the junction of externally bonded steel plates and bonded rigid supports. The reinforcement of beams with different widths on the side is studied. The results show that the effect of the rigid support on the maximum tensile stress in the concrete at the joint is quite obvious. The calculated results are in accordance with the measured stress at the site. The problem of the anchorage length of the beam-side bonded steel plate was also studied, and the corresponding anchoring length formula was given.
