Problem

Detecting multi-class structural damage in a large-scale bridge from noisy, nonstationary vibration sensor data is difficult for deep learning methods.

Why it matters

Undetected damage in long-span bridges like Tianjin Yonghe Bridge threatens public safety and critical urban infrastructure.

What the AI did

Signal processing (MEMD and Wavelet transform) extracts features from vibration signals, which are fed to tuned LSTM, 1D-CNN, and MLP models for damage classification.

Results

Impact

The abstract states the methods were applied to Structural Health Monitoring of Tianjin Yonghe Bridge, but gives no measured outcomes.
