文摘
- •
A method for generating spectrum-compatible accelerograms is proposed.
- •
Generated accelerograms capture time and frequency features of real record.
- •
The wavelet packet based procedure is flexible to use for engineering practice.
- •
The max relative fitting error of spectrum can be as small as around 6% or below.
