The aim of this project is to investigate the long-term reliability of a new earthquake strengthening technique for brick buildings. The technique involves the use of fibre reinforced polymer (FRP) strips as reinforcement for brick walls and has been shown to give substantial instantaneous strength increases. However, no research has been undertaken to ensure that the improved strength is sustained over the remaining life of the building. The only related research involves reinforced concrete which suggests that a reduction of at least 33 per cent could be expected. Hence, this project will quantify the long-term strength of FRP reinforced brickwork to enable engineers to safely apply this new cost-effective retrofit technique.

本课题的目的是研究一种新的砖房抗震加固技术的长期可靠性。该技术涉及使用纤维增强聚合物（FRP）带作为砖墙的加固材料，并已被证明可以显著提高瞬时强度。然而，没有进行任何研究，以确保在建筑物的剩余寿命内保持提高的强度。唯一相关的研究涉及钢筋混凝土，这表明预计至少可以减少33%。因此，该项目将量化玻璃钢加固砌体的长期强度，以使工程师能够安全地应用这种新的具有成本效益的改造技术。
