Shake Table Validation: Structural Response Forecasting
Model's PGA Predictions Match Measured Data within 5% Error
The hybrid ANN-PSO model's predictions were validated through a shake table test on a 1:10 scale three-story building model in Saman, Iran. Accelerometer data recorded at 100 Hz confirmed that the model's predicted Peak Ground Acceleration (PGA) values aligned with measured structural responses within a 5% error margin. This validation confirms the model's utility in forecasting structural vibration responses under seismic loads, supporting applications in structural health monitoring and seismic retrofitting strategies.
Key Findings:
- Predicted PGA values matched measured data within a 5% error margin.
- Demonstrated applicability in vibration engineering for structural health monitoring.
- Supports the identification of critical vibration thresholds for buildings.

Vibration Signal Processing & ANN-PSO Integration
- Input Features: Incorporates 12 vibration-based input features (e.g., Peak Ground Acceleration (PGA), Shear Wave Velocity (Vs30), Spectral Intensity (SI)) derived from seismotectonic and accelerometer data, capturing seismic wave dynamics.
- Signal Processing: Utilizes Fast Fourier Transform (FFT) for frequency-domain features (dominant frequencies, spectral intensities) and Discrete Wavelet Transform (DWT) with Daubechies db4 wavelet for time-frequency components, enhancing detection of transient seismic events by 12%.
- PSO Optimization: Particle Swarm Optimization is custom-coded to optimize ANN weight initialization, reducing Mean Squared Error (MSE) by 15% and training time by 26% compared to standard ANNs, improving convergence stability.
- ANN Architecture: Features a feedforward Multilayer Perceptron (MLP) with a 12-20-2 topology (input-hidden-output neurons), using tansig activation in the hidden layer and purelin in the output layer, fine-tuned with Levenberg-Marquardt algorithm.
- Regional Dataset: Trained on a dedicated, high-resolution dataset of 10,000 seismic-vibration events from the Saman region, Iran, enriched with local seismotectonic variables, allowing learning of region-specific wave-propagation patterns.
