Structural Health Monitoring

Structural Health Monitoring (SHM) modules BZ-8550 – BZ-8554 provide damage indicators, mode tracking, drift analysis and automatic file uploading and processing. Damage detection is done in the physical domain using state-space models to ensure robust and reliable damage predictions. This is different to the traditional approach of using detection in the reduced modal domain.

The benefits of SHM include:

• Catastrophic failure avoidance
• Customized structural inspections
• Optimized maintenance services
• Optimal use of structures
• Minimized downtime
• Extended lifetime of structures

Structural Health Monitoring modules BZ-8550 – BZ-8554 are available for OMA Pro Type 8762 and together they provide a completely integrated, accurate and flexible solution to ensure structures perform and can continue to perform as intended.

USE SCENARIOS

• Long-term continuous structural health monitoring of large civil engineering and mechanical structures to ensure structural integrity
• Timely indication of structural damage to determine required health management
• Automatic mode tracking (natural frequencies, damping ratios and mode shapes) as a function of analysis sessions to study mode changes due to damage
• Analysis of inter-story drift of high-rise buildings after seismic activity
• Using experienced gained from structural health monitoring to improve future designs. For example, obtaining reduction in aircraft weight without compromising structural integrity 

CAPABILITIES

• Automatic upload and processing of measurement files from designated file folders
• Two statistical subspace-based damage detection indicators (classic and robust). Robust to changes in ambient conditions
• Control chart prediction for unification of damage indicators
• 3D data view for simultaneously displaying spectra and damage indicators as a function of analysis sessions
• Definition of event triggers and configuration of alerts to be sent as auditory and visual notifications, emails and web service posts
