摘要
应用弹性力学理论分析了粘贴碳纤维加固钢筋混凝土梁前后以及考虑预载作用下加固梁的受弯全过程。计算梁体极限荷载承载力并将计算结果与试验结果进行比较。结果表明,与普通钢筋混凝土梁相比,采用FRP加固的钢筋混凝土梁的强度、刚度、抗裂缝能力、耐久性有明显提高。
Through the application of elasticity theory, this article analyzes the pre-and-after conditions of carbon fiber reinforced concrete beams, and considering the whole process of the flexural reinforcement beams under preload it examines the mechanism of carbon fiber reinforced beams. Also, the beam ultimate load bearing capacity is calculated and then the calculation with the experimental results is compared. The findings show that the stiffness of the reinforced concrete beam strengthened by FRP is apparently higher than that of the ordinary reinforced concrete beam, which is of great significance to improve the durability of reinforced concrete beams.
