Rotation measurements in structural health monitoring of civil engineering structures: a review
摘要
The need for reliable and affordable structural health monitoring of civil engineering structures drives the constant development of increasingly robust monitoring techniques. In some cases, novel sensors are developed and applied, or sensors that were never used in this particular area are studied. This is an example of gyroscope sensors, which are typically used for navigation as part of inertial measurement units, but were only recently recognised as a potential structural monitoring device. Despite extensive research on the application of these sensors in civil engineering, the studies are largely isolated from one another. To bridge this gap, the authors attempted to provide a comprehensive overview of existing solutions in reliable literature sources. In discussing the topic, an attempt was made to classify these solutions from the perspective of the measurement methods used, with a focus on rotation measurements within a dynamic range, specifically rotation rate and rotation acceleration. The advantages and disadvantages of the most used sensor technologies are also discussed, providing a reference for future studies.
