摘　　要：纤维复合材料耐久性的试验研究成为当前混凝土耐久性研究的热点。本文基于纤维复合材料基本力学性能耐久性的研究结论,结合混凝土结构设计规范与加固设计规范的承载力计算公式,提出了纤维复合材料加固混凝土构件在紫外线辐射下的耐久性计算理论。并得出紫外线老化环境对于受弯承载力仅有1.44%的影响,而对受剪承载力有11.11%的降低。结合当前该领域的研究现状,提出了6点加固建议和6点研究方向的展望。对于纤维复合材料加固混凝土试件的计算理论具有一定指导意义。The experimental study on the durability of fiber composite materials has become a hot topic in the study of concrete durability. Based on the studies of the durability of the basic mechanics performance of fiber composite materials, and combined with the design codes for concrete structures and calculation formula of bearing capacity in strengthening design codes, this paper gives the calculation theory on the durability of the concrete structures reinforced with the fiber composite materials in ultraviolet radiation . The uhra- violet aging influence on bending bearing capacity is only 1.44% , and shear carrying capacity 11.11% of reduction. Combined with the current research status in this field, the paper puts forward 6 points for strengthening and 6 prospects in the direction of research. It is a guide for the calculation theory on the concrete structures reinforced with fiber composite materials.
