项目摘要

The proposed research aims at developing innovative design and smart structural health monitoring for sustainable performance of bridge infrastructure. Focus is placed on two themes: Theme 1 - Development of Sustainable Hybrid Bridge Systems: Innovative corrosion-free hybrid systems are currently under development by the applicant. The main objective of this research is to develop an optimum design of a sustainable and more durable and cost-effective system for short- and medium-span bridges. The proposed system can apply to hundreds of bridges constructed every year. In the new system, the superstructure is built entirely from materials that are immune to corrosion. Advantages of the system include reduced self-weight and enhanced durability. The light weight reduces the required amount of prestressing and the load on the supports, resulting in a smaller size of the substructure, or allows for longer spans, which may lead to a smaller number of supporting piers in multi-span bridges and, hence, reduction in the initial cost. The enhanced durability reduces the maintenance cost and can lead to a bridge lifespan that is double or even triple that of the average traditionally constructed bridges. The long-term objective is to develop guidelines and procedures for the design, fabrication and construction of the new bridge system. Theme 2 - Development of Damage Identification Technique for Structural Health Monitoring: A vibration-based damage identification technique (DIT) is currently under development. It can detect structural damage, determine its location, and estimate its severity in in-service bridges. The DIT combines discrete wavelet transforms and spectral entropy in a relative procedure to detect and quantify damage-induced disturbances in bridge dynamic responses measured under ambient vibration. This relative wavelet entropy (RWE) based DIT is a practical means for damage identification in in-situ cases, where the bridge normal operation cannot be interrupted to perform dynamic excitation tests and when data from a reference (undamaged) state of the bridge are not available for comparison with data obtained from current (damaged) state. Preliminary results of implementing the RWE DIT in a variety of bridge components tested under static and fatigue loading have proved efficacy of the technique in identifying test-induced damage under varying operational and environmental conditions. The objective of this theme is to further develop the DIT to be able to characterize various types of damage and quantify their actual (not estimated) severity. This can be done by combining a finite element (FE) model updating procedure with the developed RWE-based technique. For this purpose, RWE indices obtained from bridge component tests will be compared with the ones obtained from the FE models. Different optimization tools will be investigated in this study to enhance accuracy of the FE models.
拟议的研究旨在开发创新设计和智能结构健康监测,以实现桥梁基础设施的可持续性能。重点关注两个主题: 主题 1 - 可持续混合桥梁系统的开发:申请人目前正在开发创新的无腐蚀混合系统。这项研究的主要目标是为中短跨桥梁开发可持续、更耐用且更具成本效益的系统的优化设计。该系统可应用于每年建造的数百座桥梁。在新系统中,上层建筑完全由耐腐蚀的材料建造。该系统的优点包括减轻自重和增强耐用性。重量轻减少了所需的预应力和支撑上的载荷,从而导致下部结构的尺寸更小,或者允许更长的跨度,这可能导致多跨桥梁中支撑墩的数量更少,因此,减少初始成本。增强的耐用性降低了维护成本,并且可以使桥梁的使用寿命是传统桥梁平均寿命的两倍甚至三倍。长期目标是为新桥梁系统的设计、制造和施工制定指南和程序。主题 2 - 用于结构健康监测的损伤识别技术的开发:目前正在开发基于振动的损伤识别技术(DIT)。它可以检测结构损坏,确定其位置,并估计在用桥梁的严重程度。 DIT 在相关过程中结合了离散小波变换和谱熵,以检测和量化在环境振动下测量的桥梁动态响应中损伤引起的扰动。这种基于相对小波熵 (RWE) 的 DIT 是现场情况下损伤识别的实用方法,在这种情况下,桥梁的正常运行不能中断以进行动态激励测试,并且桥梁参考(未损坏)状态的数据不可用。可与从当前(损坏)状态获得的数据进行比较。在静态和疲劳载荷下测试的各种桥梁构件中实施 RWE DIT 的初步结果证明了该技术在识别不同操作和环境条件下测试引起的损坏方面的有效性。该主题的目标是进一步开发 DIT,使其能够表征各种类型的损坏并量化其实际(而非估计)严重程度。这可以通过将有限元 (FE) 模型更新程序与开发的基于 RWE 的技术相结合来完成。为此,将从桥梁构件测试中获得的 RWE 指数与从 FE 模型中获得的指数进行比较。本研究将研究不同的优化工具,以提高有限元模型的准确性。
