Strong-Motion Records and Fourier Spectra for Vibration System Analysis

202.5 MB of processed strong-motion records from the K-NET and KiK-net databases, including calculated intensity measures and Fourier amplitude spectra. The dataset, authored by Haizhong Zhang and last updated in April 2026, contains MATLAB scripts for reproducing the associated research on vibration systems with linearly behaving materials.

Use Cases

• Reproducing research on Fourier amplitude spectrum scaling based on the provided MATLAB scripts and processed data.
• Analyzing ground motion intensity based on calculated measures like PGA, PGV, and Ia.
• Studying spectral ratios derived from strong-motion records for vibration system characterization.

Strengths

• Includes 202.5 MB of processed data and analysis scripts, allowing for result reproduction.
• Data sourced from authoritative seismic networks (K-NET and KiK-net, NIED).
• Released under a permissive CC-BY-4.0 license for reuse.

Limitations

• Column-level documentation is absent; field semantics must be inferred after download.
• Row count is unknown, which may limit suitability assessment.
