摘要
在以往研究工作的基础上,采用理论分析与实验研究相结合的方法,对碳纤维薄板增强钢筋混凝土梁的抗弯刚度变化进行了定量探讨。分析及实验结果表明:所采用的构件刚度的理论分析方法是有效的;与普通钢筋混凝土(RC)梁相比,碳纤维薄板增强RC梁屈服前的刚度提高了6％左右。
The bending stiffness of the strengthened reintorced concrete (RC) beam with carbon fiber-sheet was discussed using theory analysis and experiment research method, based on some works carried out by previous researchers. The results show that the theory analysis of the stiffness of RC beam in this paper is effective. Compared to RC beam, the bending stiffness of the strengthened RC beam is boosted with about 6 percent.
