【摘要】：依據(jù)171次地震中3 462組三分量地震記錄,對豎向地震動的一些特性進行了統(tǒng)計分析,結(jié)果表明:(1)在近場區(qū),豎向地震動的影響較大,峰值較大而且往往首先出現(xiàn);(2)地面震動強度越大,豎向地震動的相對比值V/H1越大;(3)V/H1峰值比的總體平均值約為0.5,V/H1≤0.65的總體累積概率約為84.5%;(4)豎向反應(yīng)譜曲線下降段的衰減指數(shù)小于水平向;豎向反應(yīng)譜拐點周期要小于水平反應(yīng)譜,而且與場地條件關(guān)系不大。
[Abstract]:Based on the 3 462 group three component seismic records of 171 earthquakes, some characteristics of vertical ground motion are statistically analyzed. The results show that in the near field region, the vertical ground motion has a great influence on the vertical ground motion. The larger the peak value is and the more the ground vibration intensity is, The larger the relative ratio of vertical ground motion (V/H1) is, the larger the ratio of V / H _ 1 to V / H _ 1 is, the overall cumulative probability is about 0.5V / H _ 1 鈮，
