1.
On the basis of typical strike-slip earthquake ground motions,the relations of ground motion amplitudes and response spectra between forward-directivity effect component (CFN),fling-step effect component (CFP) and two orthogonal coupling components (C45°,C-45°) are analyzed by considering the influence of site conditions.
以典型走滑断层型地震动为数据基础,考虑场地条件的影响,对近断层方向性效应地震动分量(CFN)、滑冲效应地震动分量(CFP)以及相互垂直的两耦合地震动分量(C45°和C-45°)的峰值、反应谱分别做了定性的比较。
2.
Ground motions with forward-directivity effect in the near-fault region are obviously different from ordinary far-field ground motions.
具有向前方向性效应特征的地震动与普通远场地震动存在明显差异。
