9526102 Kiremidjian The rapid assessment of the state of critical and conventional civil infrastructures, in normal operation as well as in natural hazard conditions is essential. In this project an intelligent system will be developed for monitoring the state of structures that utilizes advanced sensing, microprocessing, wireless transmission, and damage diagnostic methods. The monitoring system will evaluate the global damage level as well as the specific location, type, and degree of local damage to structural elements and connections. The system will be designed to periodically test and assess the condition of a structure under normal operating conditions; and will evaluate its state following extreme loads such as those caused by hurricanes, earthquakes, or blasts. Application of the monitoring system with wireless communications capabilities to both existing and newly built structures will be investigated. The research effort will focus primarily on the design and development of the distributed sensor units, site master processor, and the efficient wireless communication system ofthe damage monitoring system. Combinations of sensors will be utilized to enable assessment of the overall damage state of the structure and to identify specific locations and types of deterioration. Advanced computational algorithms will be developed to enable efficient and reliable estimation of the state of the structure. ***

9526102 Kiremidjian快速评估关键和常规民用基础设施在正常运行和自然灾害条件下的状况至关重要。 在这个项目中，将开发一个智能系统，利用先进的传感，微处理，无线传输和损伤诊断方法监测结构的状态。 该监测系统将评估结构元件和连接件的整体损坏程度以及局部损坏的具体位置、类型和程度。 该系统将被设计为定期测试和评估正常运行条件下的结构状况;并将评估其在极端载荷（如飓风、地震或爆炸引起的载荷）下的状态。 将研究具有无线通信能力的监测系统在现有和新建结构中的应用。 研究工作将主要集中在分布式传感器单元，现场主处理器，和有效的无线通信系统的损坏监测系统的设计和开发。 传感器的组合将被用来评估结构的整体损坏状态，并确定具体的位置和类型的恶化。 先进的计算算法将被开发，以使有效和可靠的估计结构的状态。 ***
