摘　　要：碳纤维材料的价格有所下降,且碳纤维材料具有强度高、质量低、施工简单、容易操作等特点,因此碳纤维作为一种新型材料在土木工程领域得到了广泛的应用。为了研究碳纤维布加固钢筋混凝土柱后的受压行为,运用ANSYS对钢筋混凝土进行数值分析,比较了未加固钢筋混凝土圆柱与用碳纤维布加固的钢筋混凝土圆柱的抗压强度变化规律以及粘贴不同碳纤维布层数对构件抗压强度有何影响。结果表明:用碳纤维采用全包裹式环向约束法加固过的钢筋混凝土圆柱要比未加固的钢筋混凝土圆柱抗压能力强。钢筋混凝土圆柱的抗压能力随着碳纤维布层数的增加而提高且钢筋混凝土柱抗压能力提高比例在减小。Because the price of carbon fiber materials has decreased,and carbon fiber materials have the characteristics of high strength,low quality,simple construction and easy operation,carbon fiber as a new material has been widely used in the field of civil engineering.In order to study the compression behavior of reinforced concrete columns with carbon fiber cloth,ANSYS was used to numerically analyze the reinforced concrete,and compared the change of compressive strength of unreinforced reinforced concrete cylinders and reinforced concrete columns reinforced with carbon fiber cloth,as well as the compression resistance of different carbon fiber cloth layers components.What is the impact of intensity.The results show that the reinforced concrete cylinder reinforced by the full-wrapped ring-oriented constraint method with carbon fiber is stronger than the unreinforced reinforced concrete cylinder.The compressive capacity of reinforced concrete cylinders increases with the increase of the number of carbon fiber cloth layers,and the proportion of compressive resistance of reinforced concrete columns is decreasing.
