A Novel Bridge Deflection Missing Data Repair Model Based on Two‐Stage Modal Decomposition and Deep Learning

open access: yesStructural Control and Health Monitoring, Volume 2025, Issue 1, 2025.
The bridge structural health monitoring (SHM) system will inevitably experience missing data. To ensure the integrity and practicability of the bridge SHM system, it is essential to repair the missing data. The existing data recovery methods mainly use the spatial correlation with other monitoring data but cannot adequately capture the time dependence ...
