A Self-Sensing Adaptive Material for New Generation of Multifunctional Highway Bridge Bearing System

The objective is to develop self-sensing adaptive bearing (SSAB) system that uses a wireless magnetorheological elastomer (MRE) sensor, which combines self-sensing (force, displacement, lateral stiffness-sensing actuation) with adaptive stiffness/vibration damping (tuned vibration absorption) into a single system. The proposed system will be capable of sensing transient displacement/load in monitoring bridge responses to environmental disturbances (such as traffic or high wind) at support locations, while at the same time producing variable stiffness properties for protection of bridges against various types of loading conditions. The successful realization of such a new multifunctional system could lead to quantum-leap changes in long-term highway bridge performance and maintenance. The information obtained through the MRE sensors will have an impact in future design of structures during extreme events.
