• Abstract:
  Researchers at the University of Nevada, Reno explored the feasibility of a self-sensing adaptive bridge bearing system. In this system, rubber bearings and sensors made of a magnetorheological elastomer (MRE) (or controllable rubber) respond to loads and vibrations through automated changes in stiffness. The system has a wireless, self-sensing capability that enables bridge owners to set threshold warnings and receive alerts via text message when a bridge reaches a predetermined level of vibration. Researchers validated the systems by testing and evaluating the performance of its adaptive features under simulated wind and traffic loads. Because the sensors collect data, they can show owners the activities and stresses that a bridge experiences.
