文摘

Earthquake excitation power spectra are estimated from incomplete process records. Process records with missing data are reconstructed using compressive sensing. Iteratively re-weighted harmonic wavelet bases are utilized for EPS estimation. A reinforced concrete building FEM is subjected to earthquake ground accelerations. System response and reliability statistics are estimated with up to 40% missing data.
