OASIS: A Real-Time Structural Monitoring System

This paper presents a commercially available real-time monitoring system using dynamic measurements for continuous evaluation of the integrity of critical civil structures. OASIS - On-Line Alerting of Structural Integrity and Safety - utilizes a variety of sensors and a unique set of parameters derived by the responsible engineer to continuously monitor structures for critical behavior. Monitoring can be done during construction for safety purposes or during operation as part of a modern maintenance program. OASIS examples include the operational monitoring of a large suspension bridge in South Korea and a cable-stay bridge in Thailand, and construction monitoring of a building in Thailand.
