Abstract
ABSTRACT We compare and analyze the consistency of observed acceleration and velocity data recorded by accelerometer and seismometer simultaneously in five aspects: time series, 5% damped response spectra, the variation and distribution characteristics of peak value ratios and spectral acceleration ratios, and correlation analysis. The results show that these two have good consistency, especially in medium-frequency bands and medium- and far-fields. In the research dataset of ground motion prediction equations (GMPEs), we propose the weight ratios of the observed acceleration and velocity records and verify that the empirical weighted ratios are reasonable and reliable and applicable to southwest China.
