| 摘 要： | 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。

| Abstract: | Taking reinforcement of a damaged building as background, this paper studies stress distri-butions of the butt joint connecting a beam and column for a reinforced concrete frame whic has been strengthened by means of sticking steel plates on both sides of the beam and a stiff support under it. The effects of consolidation with different width plates are analysed. It is very evident that the maximum tension stress in concrete nearby the beam-column joint is de-creased rapidly by adhering the stiff support. The results correspond to those measured in situ. And the anchorage length of adhered steel plate is discussed. |
