碳纤维布加固钢筋混凝土柱的研究

Study on Repair Reinforced Concrete Column by Carbon Fiber Sheet

碳纤维布加固混凝土结构是一种新型加固方法。本文在试验研究的基础上,将抗拉强度很高的碳纤维布用环氧树脂预浸成为复合增强材料;用环氧树脂粘结剂沿受拉方向粘贴在要补强的柱子上,形成一个新的复合体,使补强碳纤维布与原有钢筋混凝土共同受力,增大结构的抗剪、抗弯强度和提高柱的延性。

It is a new form of reinforcement for concrete structure to strengthen them with carbon fiber sheets (CFS), which dipped in epoxy resin to form compound material. Based on series experimentation study, CFS are affixed along reinforced concrete column in epoxy resin forming a new composite. CFS and old reinforced concrete working together, it improve the strength and deformability of the columns.
