| 摘 要： | 文章分析了FRP片材加固混凝土结构的温度应力,研究表明当温度降低时,在碳纤维内部会产生较大的正应力,而处在粘贴位置的混凝土会产生较大的拉应力。应力的大小主要与FRP片材的弹性模量、热膨胀系数、碳纤维厚度和温差值的大小等参数有关。 |
| 关 键 词： | 纤维增强塑料(FRP)片材 混凝土 加固 温度应力 |

| Abstract: | In this paper, the thermal stress of concrete structures strengthened by fiber reinforced plastic(FRP) laminates is calculated and analyzed. The analysis shows that the decrease of temperature can cause normal stress in the FRP and tensile stress in the concrete near the FRP laminates,and that the values of the stresses are related with the FRP's elastic modulus,the thermal expansion coefficient,the depth of the FRP laminate and the changed value of temperature. |
| Keywords: | fiber reinforced plastic(FRP) laminate concrete reinforcing thermal stress |
