RESPONSE SPECTRA OF 61 EARTHQUAKE GROUND ACCELERATION RECORDS ARE CALCULATED, AND EFFECTS OF SUBSOIL CONDITIONS ON THE SHAPES OF RESPONSE SPECTRUM CURVES ARE STUDIED. RELATIONSHIPS BETWEEN THE SHAPES OF RESPONSE SPECTRUM CURVES AND EARTHQUAKE MAGNITUDE, MICROTREMOR SPECTRA, AND SPECTRUM INTENSITIES ARE EXAMINED. THE STRONG-MOTION EARTHQUAKE STATIONS ARE CLASSIFIED INTO THREE GROUPS IN ACCORDANCE WITH THE SHAPES OF RESPONSE SPECTRA, WHICH ARE CALCULATED FROM THE ACCELEROGRAMS RECORDED AT EACH STATION. THE VARIATION RANGES OF THE SUBSOILS OF THE STATIONS IN EACH GROUP ARE STUDIED. THE AVERAGE RESPONSE SPECTRA OF 0%, 5%, AND 10% OF CRITICAL DAMPING ARE COMPILED FOR THE THREE GROUPS. THE AVERAGE RESPONSE SPECTRUM OF THE GROUP B IS COMPARED TO AVERAGE RESPONSE SPECTRA PRESENTED PREVIOUSLY BY OTHER INVESTIGATORS. /AUTHOR/
