This project aims to develop a novel structural system leading to more economical concrete bridge construction by utilising a customised structural fuse. A significant margin of safety is required in structural design to account for accidental over-loading and to reduce the risk of structural collapse. Such a margin leads to more material usage. Incorporation of a fuse into the structure that is triggered upon over-loading will cause a safer failure mode and prohibit further increase of loading, both of which result in a reduced structure without undermining safety. The project is expected to advance structural theory, and also provide significant benefits to the construction industry via cost reduction and more eco-friendly constructions.

该项目旨在开发一种新的结构系统，通过使用定制的结构保险丝，实现更经济的混凝土桥梁建设。在结构设计中需要有很大的安全裕度，以考虑意外超载和减少结构倒塌的风险。这样的裕度导致更多的材料使用。在结构中安装一个在过载时触发的引信，将造成一种更安全的故障模式，并禁止进一步增加载荷，这两种情况都导致结构缩小而不损害安全。该项目预计将推进结构理论，并通过降低成本和更环保的建筑为建筑行业带来重大利益。
