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.
