Abstract0511046Henry Yang, Univ. Santa BarbaraThis project aims at the development of a hybrid structural health monitoring and management of civil and mechanical structures through Integrated Sensing module for Monitoring, Decision-Making, Model Management, and Control.Such modules provide the ability of assessing the health condition of structures at both global and local levels, and offers improved performance over traditional methods focused on either level. One objective is to develop reliable global damage detection and identification methods. The structure will be modeled as integration of several subsystems. By monitoring the change in the dynamic behavior within each subsystem, the region of damage can be located at the subsystem level. Another objective involves the development of local damage detection methods. The novel sensing technique using ultrasonic infrared imaging will be adopted and continuously developed in this study. The final objective is to propose that these two methods, global and local, interact in a mutually complimentary manner during real time monitoring process to assure optimal monitoring and management results, including the determination of exact location and characterization of damage and accounting for the effects from unknown environmental conditions.

摘要0511046杨亨利，大学。圣巴巴拉该项目旨在通过用于监测、决策、模型管理和控制的综合传感模块，开发土木和机械结构的混合结构健康监测和管理。这些模块提供在全球和本地两个层面评估结构健康状况的能力，并提供比侧重于任何一个层面的传统方法更好的性能。一个目标是开发可靠的全球损害检测和识别方法。该结构将被建模为几个子系统的集成。通过监测每个子系统内动态行为的变化，可以在子系统级别上定位损坏区域。另一个目标涉及开发局部损害检测方法。本研究将采用并不断发展基于超声红外成像的新型传感技术。最终目标是提出，在实时监测过程中，这两种方法--全球的和当地的--以互补的方式相互作用，以确保最佳的监测和管理结果，包括确定损害的准确位置和特征，并考虑未知环境条件的影响。
