Strain-based Fatigue Crack Monitoring of Steel Bridges using Wireless Elastomeric Skin Sensors
| 项目名称： | Strain-based Fatigue Crack Monitoring of Steel Bridges using Wireless Elastomeric Skin Sensors |
| 摘要： | The main objective of this proposed research is to provide state departments of transportation (DOTs) a practical and cost-effective long-term fatigue crack monitoring methodology using a wireless elastomeric skin sensor network. This research is intended to demonstrate the value-added of fatigue crack monitoring of steel bridges using wireless skin sensors over the traditional bridge inspection in the following ways: (1) The ability to collect objective information regarding fatigue crack activity under in-service loading of bridges in a continuous manner, improving the assessment, safety, and reliability of fractural-critical bridges, and providing early warning regarding evolving internal defects; (2) The ability to improve prioritization of bridge repairs (condition-based maintenance) and retrofit for fatigue cracks so as to maximize the effectiveness of limited resources; and (3) The ability to better assess the effectiveness of various fatigue repair and retrofit techniques for steel bridges through long-term crack monitoring. |
