Abstract
In this paper, considering that valuable information concerning the aseismic design of structures are hidden in saturated records, a more resonable method to mend the Japan Meteorological Agency's (JMA) low-magnification seismograms is proposed through a shaking table test. This method is able to mend a saturated seismogram with an error lower than 10% for engineering purpose. Seven JMA's records with saturations obtained during the 1968 Tokachi-oki earthquake, the 1978 Miyagiken-oki earthquake and the 1983 Nihonkai-chubu earthquake are mended by the proposed method. Consequently, some mended displacement seismograms are found to give much higher response spectra than design values for long-period (5 to 15 seconds) structures.
