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，使用FRP复合材料来加强现有结构。但是，在应用程序中，一些基本方面仍然没有充分理解，特别是与循环负荷下的frp转换成员的性能和行为相关的基本方面以及环境对这种行为的作用的作用。通过严格的实验，分析和数值研究，拟议的研究将有助于更好地理解单调和循环载荷下的翻新系统行为以及环境效应。这将构成开发用于安全应用程序的集成设计方法的基础，并更好地评估此类系统的耐用性，这些系统正变得广泛。
