This paper presents the analysis of peak ground motion data from 1,368 horizontal acceleration records of 201 earthquakes at 78 free field sites. The analysis used only those records which have horizontal acceleration in any direction 5 cm/s2 or greater. Conversion factors of peak ground motion indices and acceleration response spectrum among different definitions of peaks were investigated considering the use in attenuation and damage estimation relationships. Each pair of two orthogonal horizontal components was combined in the time domain to get the maximum resultant peak ground motion indices and acceleration response spectrum in the horizontal plane. From the analysis, the means of larger/resultant ratio were found to be 0.934 for acceleration, 0.926 for velocity and 0.913 for displacement. The similar decreasing trend was observed for the means of the average/resultant ratio of the ground motion indices and acceleration response spectrum. キーワード（英）： - 記事区分： - 区分 　　　委員会論文集
