A large number of metallic structures such as bridges, offshore platforms and large mining equipment are aging. Retrofitting such structures is becoming increasingly important in the 21st century. Using an advanced material, Carbon Fibre Reinforced Polymer (CFRP), to strengthen metallic structures is very promising. This project aims to develop reliable CFRP strengthening systems for aging metallic bridges. It aims to make a breakthrough in understanding of the fatigue crack propagation in CFRP-metal composite system under combined loading. It intends also to produce practical guidelines for engineers to strengthen aging metallic bridges.

大量的金属结构，如桥梁、海上平台和大型采矿设备正在老化。在世纪，改造这种结构变得越来越重要。碳纤维增强聚合物（CFRP）是一种先进的金属结构加固材料，具有广阔的应用前景。该项目旨在为老化的金属桥梁开发可靠的CFRP加固系统。旨在对CFRP-金属复合材料体系在复合载荷作用下的疲劳裂纹扩展规律的认识有所突破。它还打算为工程师提供实用指南，以加强老化的金属桥梁。
