粘贴或包裹碳纤维布加固钢筋混凝土结构不仅得到了广泛研究,而且已被成熟应用于工程实践。在混凝土保护层嵌入碳纤维(或玻璃纤维)条加固钢筋混凝土结构,具有不改变构件的截面尺寸和外观,不影响建筑效果等优点,正在成为一种新的加固技术,尤其适用于公共建筑、经典建筑的加固。选择结构中常用的钢筋混凝土简支单向板为试验对象,在板的保护层分别嵌入6条厚度1.4mm宽度20mm的碳纤维布,研究试件的爆炸响应以及爆炸中所表现的破坏特征,尤其是嵌入的碳纤维的破坏,研究碳纤维在钢筋混凝土板爆炸动力响应中的作用。试验结果证明,保护层嵌入碳纤维(CFRP)可以有效地用于加固遭受爆炸荷载的钢筋混凝土构件和结构。
Paste or wrap carbon fiber reinforced concrete reinforced concrete structure has not only been extensively studied, but also has been used in engineering practice. Reinforced concrete structure with carbon fiber (or glass fiber) embedded in the concrete protective layer has the advantages of not changing the sectional size and appearance of the component and not affecting the construction effect and is becoming a new reinforcement technology, and is especially suitable for public buildings, classic Building reinforcement. Select the commonly used reinforced concrete simple-supported one-way plate as the test object, respectively, embedded in the protective layer of the plate 6 1.4mm width 20mm carbon fiber cloth to study the explosive response of the specimen and the explosion characteristics of the failure of the show, in particular Is the destruction of embedded carbon fiber, carbon fiber in the study of the role of the dynamic response of reinforced concrete slab explosion. The experimental results show that CFRP can be effectively used to reinforce reinforced concrete members and structures subjected to blast loads.
