North American Euro-Pacific Workshop for Sensing Issues in Civil Structural Health Monitoring

摘要要实施成功的结构健康监测计划，需要选择和放置适合于测量影响结构系统性能和健康的关键参数的传感器。除了结构上的考虑外，传感器的选择还需要基于与材料的兼容性以及测量范围和范围。尽管传感器领域最近取得了技术进步，但其在民用基础设施系统中的应用遇到了许多挑战。阻碍传感器技术快速实施的一些主要问题包括：结构尺寸大，需要多路复用传感器，恶劣的施工环境，恶劣的暴露条件，长期的可靠性和耐久性，以及不存在用于测量土木结构中相关重要参数的传感器。有必要制定一个协调的研究方案来解决这些问题。拟议的研讨会将帮助NSF确定优先顺序并规划协调研究计划，以研究和开发传感器和传感器组件，用于桥梁、大坝和隧道等土木工程类型的结构的特定用途。研讨会将讨论材料性能和传感能力之间的关键联系。讲习班的最终成果将是一本详细介绍实践情况的精装书和一份概述详细的国家研究五年计划的综合报告。

AbstractImplementation of successful structural health-monitoring programs requires selection and placement of sensors suitable for measurement of key parameters that influence the performance and health of the structural system. In addition to the structural considerations, sensors need to be chosen based on compatibility with the materials and the range and scope of measurements. Despite the recent technological advances in the field of sensors, their applications in civil infrastructure systems have met with many challenges. Some of the primary issues of concern that impede rapid implementation of sensor technologies include large size of structures and the need for multiplexing a multitude of sensors, harsh construction environment, adverse exposure conditions, long term reliability and durability, and inexistence of sensors for measurement of relevant parameters of importance in civil structures. There is a need for development of a coordinated research program to address these issues. The proposed workshop will aid NSF in prioritization and planning of a coordinated research program for research and development of sensors and sensor packages for specific use of civil engineering type of structures, such as bridges, dams and tunnels.The workshop will address the key link between the material performance and the sensing capability. The final products of the workshop will be in the form of a hardbound book detailing the state-of-the-practice, and a comprehensive report outlining a detailed five-year national plan for research.
