Title: "Cyber-physical Approaches to the Design of Structural Systems."
Design trends for civil infrastructure are shifting from prescriptive code procedures to performance-based methods. The structural engineers of tomorrow will be asked to produce lighter, taller, and more cost-effective designs to meet new performance goals. Sustainable solutions that consider long-term costs and benefits will require new approaches to design and optimization. In civil engineering, experimental testing remains essential to capture complex behavior for which numerical models are insufficient or unavailable. These high-fidelity experimental components can be linked to numerical algorithms through sensing and actuation to create a cyber-physical systems (CPS) design framework.
One application of CPS is “model-in-the-loop” testing, where the complete response of a structure is obtained from the experimental evaluation of components of interest, coupled with the online numerical simulation of the remainder of the structure. A second application of CPS is the proposed “loop-in-the-model” testing, where a specimen undergoes physical changes as it approaches a numerically-driven optimal solution. Recent advances in the use of CPS for the design and optimization of civil infrastructure are discussed with a focus on wind engineering and earthquake engineering. Examples include design details to reduce the effects of wind loads on structures and new seismic protective systems for low-frequency structures. Cyber-physical systems stand to greatly enhance the capabilities of laboratories worldwide, enabling researchers to deliver more reliable and cost-effective solutions in a performance-based design environment.
Brian M. Phillips is an associate professor in the Department of Civil and Coastal Engineering at the University of Florida. He received his bachelor’s degree from the University of Pittsburgh in 2006, master’s degree from the University of Illinois in 2008, and PhD degree from the University of Illinois in 2012. His research interests include structural dynamics, structural control, protective systems, wind engineering, and earthquake engineering. His current focus is on the use of cyber-physical systems for the design and optimization of civil infrastructure.
