機械式およびディジタル強震計の記録精度について-SMAC強震計記録の補正法の検討-

Abstract

An experimental study has been performed for develoment of correction technique ofstrong motion records obtained by the SMAC-B2 accelerograph. The shaking tests havebeen carried out both for the long period and the short period range by using the typicalstrong motion accelerographs and relevant equipments: they are the SMAC-B2 accelerograph, the digital accelerograph SAMTAC-17E, the AKASHI Servo accelerograph, and the Displace-ment Tape Measure. The cut-off frequencies for the correction filter for the SMAC-B2accelerograms have been examined comparing with the SAMTAC accelerograms and displace-ment time history obtained by the Displacement Tape Measure. The applicability of thecorretion filter for the strong motion records have been examined by using the Japanesetypical records obtained by the SMAC-B2 accelerograph.
