震源机制对近场地震动反应谱的影响
|
摘要
将欧洲及其毗邻地区以及美国的部分近场强震记录按照震源机制进行分组,详细的分析了震源机制对水平和竖向分量地震动加速度反应谱放大系数以及竖向与水平向反应谱比值的影响。结果表明震源机制对震级不同的地震动以及地震动不同分量反应谱的影响程度不同;震源机制不仅影响反应谱峰值大小以及峰值位置,还在一定程度上影响反应谱的形状。
According to the focal mechanism the 92 groups of near field earthquake records from Europe,its neighbor regions and America are divided into 4 types.Based on the data,the effects of focal mechanism on near filed response spectrum and response spectra ratio in vertical and horizontal component of the acceleration records are analyzed.The results show that the effect of focal mechanism on response spectrum of different magnitude and different components has different features.Focal mechanism has not only some effects on the peak and peak position of response spectrum,but also on the shape of response spectrum in a certain extent.
