地震动的脉冲效应取决于它的方向,因此有必要识别具有最强脉冲的地震动的方向。本文提出了一种简单而有效的多分量地震动最强脉冲识别方法,通过将地震动旋转到与最大峰值地震动速度(PGV)相关的方向上。结果表明,脉冲状的地面运动分量的最大PGV值的方向有可能产生最大的平均/中值比旋转到所有其余的方向的组件的延性。所提出的方法与现有的方法进行比较,进一步表明,所提出的maximumPGVmethodology可以准确地识别最强的脉冲。确定的最强脉冲可以在工程实践中用于估计结构的最大地震需求。
The ground motion pulse-like effect depends on its orientation, it is thus necessary to identify the direction of the ground motion with the strongest pulse. A simple yet efficient method to identify the strongest pulse over all orientations in multicomponent ground motions is presented in this study, through rotating the ground motions to the orientation associated with the maximum peak ground velocity (PGV). It is demonstrated that the pulse-like ground motion components in the orientation with the maximumPGVvalue have the potential to produce the largest mean/median ductility than the components rotated to all remaining orientations. A comparison of the proposed methodology with an existing method is also performed, further demonstrating that the proposed maximumPGVmethodology can accurately identify the strongest pulse. The determined strongest pulse can be utilized in engineering practice to estimate the maximum seismic demands on structures.
