Monitoring and Maintaining the Structural Health of Bridges Using Vibration Characteristics

桥梁是我们有形基础设施系统的重要组成部分，仅在昆士兰州就有近3000座桥梁的年维护成本超过2000万美元，重置价值超过20亿美元。必须确保这些桥梁在任何时候都能安全高效地发挥作用。桥梁故障将导致正常生活中断和昂贵的维修费用。为此，这个项目将开发一个创新的结构健康监测系统，以监测和维护我们的桥梁的结构健康。项目成果将立即在澳大利亚和海外应用，为社区带来经济和社会效益。

Bridges form an important part of our physical infrastructure system and in Queensland alone there are nearly 3000 bridges with an annual maintenance cost in excess of 20 million dollars and a replacement value in excess of 2 billion dollars. It is necessary to ensure that these bridges function safely and efficiently at all times. Bridge failure will cause disruption to normal lives and expensive repairs. Towards this end, this project will develop an innovative structural health monitoring system to monitor and maintain the structural health of our bridges. The project outcomes will have immediate applications in Australia and overseas with economic and social benefits to the community.
