摘　　要：碳纤维材料以其高强、轻质、耐腐蚀等优良性能广泛应用于混凝土结构加固领域。为了充分保证建筑结构的安全性,现以某办公楼加固工程为例,阐述了应用碳纤维材料对钢筋混凝土构件进行结构补强加固的设计原理,提出了考虑二次受力时应如何进行加固计算以及应用碳纤维布进行结构加固时应注意的事项等。Carbon fiber sheets with some fine properties such as high-strength,light-weight,corrosion-resistance are applied to RC structure extensively.Take an office building as an example. The design principle of the concrete members reinforced by carbon fiber material is explained.The methods of calculation are proposed when twice loading is considered.It is also pointed out that certain item should be paid attention to when the structure is strengthened by carbon fiber sheets.

关 键 词：混凝土构件 碳纤维 加固
