Purpose
Dynamic testing of bridge span structures, natural frequency determination, vibration diagnostics
Description
Equipment set for express bridge testing. Methodology was developed at OAO CNIIS from 1989 to 2006. In 2001, Methodological Recommendations for Vibration Diagnostics of Road Bridges were approved at Rosavtodor. Dynamic data is recorded in digital form to electronic storage with subsequent digital processing.
Operating Principle
ATt90 accelerometers are installed on left and right sidewalks in the middle section of the span. MS4812 Controller records vibrations. Simultaneously, traffic data is manually recorded (speed, direction, time). Data processing is performed by ex32.exe program.
Applications
- •Dynamic bridge testing
- •Vibration diagnostics of span structures
- •Natural frequency determination
- •Technical condition assessment
- •Scientific and technical reports
