CFRP不同层数对钢筋混凝土受弯构件加固后性能分析
|
摘要
碳纤维布(CFRP)作为一种新型的补强修复材料,以其轻质、高强等优良的性能,及施工简便、不增加构件截面尺寸等优点,在混凝土结构加固中得到大量的应用。本文通过实验数据对挠度、裂缝和承载力进行分析得出CFRP不同层数对钢筋混凝土受弯构件加固后性能分析结果。
As a new type of reinforcing material, CFRP get a lot of applications in the concrete structure reinforcement with its light,high strength,good performance,easy construction and not increasing the size of the member section size.In this paper,through analyzing the deflection,crack and bearing capacity by the experimental data,come to the conclusion that the performance of the reinforced concrete flexural members strengthened with different levels of CFRP.
