Wireless Joint Monitoring System (w-JMS) for Safety of Highway Bridges

| 摘要： | Maintaining the safety and stability of a bridge is a series concern of our nation. ASCE report cards repeatedly give low grades for our bridges indicating the immediate needs for repair and maintenance. The bridges’ expansion joints of our regions are especially vulnerable because of continuous thermal expansions and shrinkage under the severe weather situation in New England. Although major bridges were visually inspected every 2 years to check their conditions which are time consuming, costly, that method often times fails to provide the necessary information if not inspected in the time frame. To assist timely maintenance and increase structures’ life span, a low-cost continuous monitoring system is desired. The objectives of this research project are to develop a wireless monitoring system for bridges’ expansion joints and to deploy the sensors on a field bridge under changes in temperature, humidity, and other live loads. The proposed project will provide comprehensive structural health monitoring framework using commercial wireless sensors networks that can be readily deployed in the field structures for real-time damage alert to the bridge owners. The eventual vision of the project is to increase the service life of our bridges by timely maintenance by real-time continuous monitoring. |
