Satish Nagarajaiah

Professor of Civil and Mechanical Engineering

Research Summary

Dr. Satish Nagarajaiah's teaching and research interests are in the areas of structural dynamic systems; seismic protection; earthquake engineering; smart structures; system identification; structural health monitoring; fault and damage detection; sensing and monitoring of structures subjected to earthquake, wind and waves; applied nanotechnology; and offshore structures. His current research focuses on seismic protection with novel negative stiffness systems, smart structures, health monitoring of deepwater risers and damage detection, and nanosensors in projects funded by the National Science Foundation, Department of Energy, Air Force Office of Scientific Research and other private industries.

Satish Nagarajaiah’s main research thrust in seismic/vibration isolation and smart structures has focused on semiactive, adaptive, passive, variable stiffness and damping structural systems. His group has performed widely cited research on variable stiffness structural systems and smart tuned mass dampers. Smart/adaptive tuned mass dampers with variable stiffness systems that he and his team developed lead to full scale implementation in China. His main research thrust in system identification and control has centered on the development of new time-frequency algorithms. In a recently concluded Institute/center funded by National Aeronautics and Space Administration (Texas Institute of Intelligent Bio-Nano Materials and Structures for Aerospace Vehicles—in which he served as co-principal investigator) his team conducted widely cited research on nanocomposite based strain sensing—one of the first in the world to explore the potential of macrostrain sensing using nanomaterials. Although most of his group’s research efforts (80% of the effort) are theoretical and analytical, the group believes in small scale experimental verification and performs innovative testing (20% of the effort). The group’s key research contributions have resulted in widely cited journal papers and U.S. patents.
