Resilient and Advanced Infrastructure Laboratory (Rail)

RAIL and UVa Logos
The  research in the Resilient and Advanced Infrastructure Laboratory (RAIL) focuses on applying smart technologies and interdisciplinary expertise to the development of resilient and sustainable civil infrastructure systems.  The actively pursued areas are:  (1) development of innovative structural systems and design strategies to enhance the performance and safety of structures; (2) application of advanced materials for disaster resistant design of structures as well as repair and retrofit of deficient and aging civil infrastructure; (3) development of damage detection and non-destructive evaluation techniques for structural health monitoring of civil infrastructure systems.

The Resilient and Advanced Infrastructure Laboratory is equipped for component level testing and allows for multiple loading configurations under static and dynamic conditions. The laboratory is equipped for performing real-time hybrid simulation experiments, in which scale experiments and numerical simulations are coupled, allowing for a real-time system level interaction while only testing a substructure component.
