课题：Predicting structural failure of FRP-wrapped concrete columns

Project Description:
The pursuit to enhance life-cycle performance and reduce the carbon footprint of new infrastructure, such as bridges, will increasingly drive construction towards the use of cost-efficient, high performance, lightweight and durable materials. Moreover, considerable existing infrastructure was not designed for the continuously increasing traffic load, or the extreme climactic events such as hurricanes and flooding; with recent evidence of links between anthropogenic climate change and increased tremor activity. Consequently, many existing structures require strengthening work to preserve or extend their service life. The optimal use of high performance and durable materials is essential for both new construction and retrofitting of existing structures.

Advanced fibre-reinforced polymer (FRP) composites have superior specific strength, stiffness and durability compared to traditional structural materials such as steel and concrete. They are extensively used in the latest generation of aerospace and marine platforms which are often less sensitive to the cost of raw materials. An increasing level of research is being conducted on their application in civil construction, particularly as strengthening material on existing structures. One common application is for strengthening concrete columns and bridge piers by wrapping. A challenging issue in this application is that the rupture strain of the FRP in wrapped columns is found to be much lower (40-70%) than coupon test results indicate, restricting the full exploitation of this material. To date, a full explanation of this phenomenon is still outstanding. This is a challenging problem as it involves the complex behaviour of localized concrete deformation, interaction between the concrete, fibres and adhesive, and damage of FRP.

The aim of this project is to identify the cause of this lower rupture strain and thus develop innovative ways to make full use of the FRP, using combined expertise from both Civil and Aerospace Engineering. The project will involve sophisticated experiments and advanced numerical modeling of composite damage, developed for the aerospace industry, as well as advanced models developed for concrete, incorporating modern fracture mechanics. The project shall lead to new design methods for much more efficient strengthening of concrete columns. The outcome will also have much wider implications for understanding the behaviour of FRP and its interaction with other construction materials.
