๐ข Case Study: High-Fidelity SHM of a 21-Story High-Rise Building
Traditional structural-health-monitoring (SHM) often faces challenges balancing precise damage localization with real-time monitoring. Our solution combines Seismic Ambient Noise (SAN) with machine-learning algorithms and has been validated on a 21-story building in Shanghai.
Setup: 22 SmartSolo IGU-16HR 3C nodes were deployed floor-by-floor (from the basement to the 21st floor) + 2 ground stations. The instruments continuously recorded data at a sampling rate of 250 Hz over a 22-day campaign, successfully capturing two Beaufort Wind Force 8-9 strong-wind events.
Key Results:
โ
Captured non-uniform stiffness distribution (frequencies 0.38โ0.45Hz) under strong wind.
โ
Precisely localized an approximate 2% reduction in wave velocity between F6-F7 and F9-F10, marking zones of stress concentration.
Conclusion: All 24 units performed flawlessly for 22 days. This confirms the technical feasibility of dense nodal arrays for building SHM, proving SmartSolo's exceptional stability and high-resolution measurement performance within complex urban environments.
