Bridge failures have occasionally been reported around the world. Condition assessment of bridges is vital to maintain their safety. It is difficult to assess quantitatively the deterioration and damage using traditional methods. Vibration-based methods are very sensitive to noise in vibration measurement and error in finite element modelling. This project will study the effects of measurement noises and finite element model errors on bridge condition assessment, and develop improved techniques for predicting load carrying capacities of bridges. The technique developed will be applied to Main Roads WA bridges, will also be applicable to the assessment of other types of structures.

世界各地时常有桥梁故障的报道。桥梁的状况评估对于维护其安全至关重要。使用传统方法很难定量评估恶化和损坏。基于振动的方法对振动测量中的噪声和有限元建模中的误差非常敏感。该项目将研究测量噪声和有限元模型误差对桥梁状况评估的影响，并开发预测桥梁承载能力的改进技术。开发的技术将应用于西澳主要道路桥梁，也将适用于其他类型结构的评估。
