Abstract
Abstract The objective of this research is to develop advanced distributed monitoring and control systems for civil infrastructure. The approach uses a cyber-physical co-design of wireless sensor-actuator networks and structural monitoring and control algorithms. The unified cyber-physical system architecture and abstractions employ reusable middleware services to develop hierarchical structural monitoring and control systems. The intellectual merit of this multi-disciplinary research includes (1) a unified middleware architecture and abstractions for hierarchical sensing and control; (2) a reusable middleware service library for hierarchical structural monitoring and control; (3) customizable time synchronization and synchronized sensing routines; (4) a holistic energy management scheme that maps structural monitoring and control onto a distributed wireless sensor-actuator architecture; (5) dynamic sensor and actuator activation strategies to optimize for the requirements of monitoring, computing, and control; and (6) deployment and empirical validation of structural health monitoring and control systems on representative lab structures and in-service multi-span bridges. While the system constitutes a case study, it will enable the development of general principles that would be applicable to a broad range of engineering cyber-physical systems. This research will result in a reduction in the lifecycle costs and risks related to our civil infrastructure. The multi-disciplinary team will disseminate results throughout the international research community through open-source software and sensor board hardware. Education and outreach activities will be held in conjunction with the Asia-Pacific Summer School in Smart Structures Technology jointly hosted by the US, Japan, China, and Korea.

Professor Shirley J. Dyke holds a joint appointment in Mechanical Engineering and Civil Engineering at Purdue University. She is the Director of the NASA funded Resilient ExtraTerrestrial Habitat Institute (RETHi) and the Director of Purdue's Intelligent Infrastructure Systems Lab at Bowen Lab. Dyke is the past Editor-in-Chief of the journal Engineering Structures. Her research focuses on the development and implementation of “intelligent” structures, and her innovations encompass structural control technologies, structural health monitoring, real-time hybrid simulation, and machine learning and computer vision for structural damage assessment. She was awarded the Presidential Early Career Award for Scientists and Engineers from NSF (1998), the George Housner Medal by ASCE (2022), the SHM Person of the Year Award (2021), the International Association on Structural Safety and Reliability Junior Research Award (2001) and the ANCRiSST Young Investigator Award (2006). She has also led many educational programs, including Research Experiences for Undergraduates, GK12, and the University Consortium on Instructional Shake Tables. She holds a B.S. in Aeronautical and Astronautical Engineering from the University of Illinois, Champaign-Urbana in 1991 and a Ph.D. in Civil Engineering from the University of Notre Dame in 1996. Dr. Dyke was the Edward C. Dicke Professor of Engineering at Washington University in St. Louis and was on the faculty there from 1996 until 2009. She served as the Co-leader for Information Technology for the NSF-funded Network for Earthquake Engineering Simulation (NEES) building a community-driven Cyberinfastructure Platform for the earthquake engineering community.
