Use of FRP composites for strengthening of existing structures have rapidly increased in the last decade. However, in applications, some fundamental aspects are still not well understood, specifically those related to performance and behavior of FRP-retrofitted members under cyclic loading and the role of environmental effects on this behavior. The proposed research, through rigorous experimental, analytical, and numerical studies, will contribute to better understanding of retrofitted systems behavior under monotonic and cyclic loads combined with environmental effects. This will form a basis for development of an integrated design methodology for safe applications and for better assessment of durability of such systems, which are becoming widespread around the world.

在过去的十年中，FRP复合材料用于加固现有结构的使用迅速增加。然而，在应用中，一些基本方面仍然没有得到很好的理解，特别是那些有关的性能和行为的FRP加固构件在循环荷载下，环境效应对这种行为的作用。拟议的研究，通过严格的实验，分析和数值研究，将有助于更好地了解改造系统的行为下单调和循环荷载结合环境影响。这将为制定安全应用的综合设计方法和更好地评估这种系统的耐久性奠定基础，这种系统在世界各地越来越普遍。
