Fatigue Strengthening of Metallic Bridges using Carbon Fibre Reinforced Polymer System

大量的桥梁、海上平台和大型矿山设备等金属结构正在老化。在21世纪，改造这些结构变得越来越重要。使用一种先进的材料，碳纤维增强聚合物（CFRP），加强金属结构是非常有前途的。本项目旨在为老化的金属桥梁开发可靠的碳纤维布加固体系。旨在突破对复合载荷作用下cfrp -金属复合材料疲劳裂纹扩展的认识。它还打算为工程师提供实用指南，以加强老化的金属桥梁。

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.
