“…Mena and Mai [7] proposed to use a spectrogram analysis for detecting pulses, in which a key parameter, representing the window length, and scaling with the earthquake magnitude, needs to be pre-determined. Hayden et al [10] developed a new pulse-classification scheme, which involves several somewhat complex steps, like filtering the record, identifying the largest PPV pulse, and scoring the motion. Based on a cumulative pulse extraction method, Lu and Panagiotou [9] presented an iterative method for extracting multiple pulses.…”

Summary This study proposes an improved energy‐based approach for quantitative classification of velocity‐pulse‐like ground motions. The pulse amplitude is determined, in its value and in time location, by the amplitude of the half‐cycle pulse having the largest seismic energy. After conducting statistical analyses, a newly‐determined threshold level for selecting pulse‐like ground motions is derived; and then what followed is a comparison analysis of three pulse‐detecting schemes, one using the wavelet analysis, the other two using the energy concept. It is believed that other than providing a useful way of classifying pulse‐like ground motions for structural demand analysis, knowledge of this work could also benefit the development of the ground motion prediction equations accounting for pulse effects, and further to aid the probabilistic seismic hazard analysis in a near‐fault environment.

“…The fling-step and forward-directivity are widely recognized as special keywords to characterize such near-fault ground motions (Mavroeidis and Papageorgiou, 2003;Bray and Rodriguez-Marek, 2004;Kalkan and Kunnath, 2006;Mukhopadhyay and Gupta, 2013a,b;Zhai et al, 2013;Hayden et al, 2014;Yang and Zhou, 2014). Especially, Northridge earthquake in 1994, Hyogoken-Nanbu (Kobe) earthquake in 1995, and Chi-Chi (Taiwan) earthquake in1999 raised special attention to many earthquake structural engineers.…”

“…At the same time, the effects of near-fault ground motions on structural response have been studied extensively (Bertero et al, 1978;Hall et al, 1995;Sasani and Bertero, 2000;Alavi and Krawinkler, 2004;Makris and Black, 2004;Mavroeidis et al, 2004;Kalkan and Kunnath, 2006;Xu et al, 2007;Rupakhety and Sigbjörnsson, 2011;Yamamoto et al, 2011;Minami and Hayashi, 2013;Khaloo et al, 2015;Vafaei and Eskandari, 2015). These many investigations made clear the characteristics of the fling-step and forward-directivity inputs (Mavroeidis and Papageorgiou, 2003;Bray and Rodriguez-Marek, 2004;Kalkan and Kunnath, 2006;Mukhopadhyay and Gupta, 2013a,b;Zhai et al, 2013;Hayden et al, 2014;Yang and Zhou, 2014). It should be mentioned that Northridge earthquake in 1994, Hyogoken-Nanbu earthquake in 1995, and Chi-Chi earthquake in 1999 brought strong attention to earthquake structural engineers and designers.…”

A dynamic stability criterion for elastic-plastic structures under near-fault ground motions is derived in closed form. A negative post-yield stiffness is treated in order to consider the P-delta effect. The double impulse is used as a substitute of the fling-step near-fault ground motion. Since only the free vibration appears under such double impulse, the energy approach plays a critical role in the derivation of the closed-form solution of a complicated elastic-plastic response of structures with the P-delta effect. It is remarkable that no iteration is needed in the derivation of the closed-form dynamic stability criterion on the critical elastic-plastic response. It is shown via the closed-form expression that several patterns of unstable behaviors exist depending on the ratio of the input level of the double impulse to the structural strength and on the ratio of the negative post-yield stiffness to the initial elastic stiffness. The validity of the proposed dynamic stability criterion is investigated by the numerical response analysis for structures under double impulses with stable or unstable parameters. Furthermore, the reliability of the proposed theory is tested through the comparison with the response analysis to the corresponding onecycle sinusoidal input as a representative of the fling-step near-fault ground motion. The applicability of the proposed theory to actual recorded pulse-type ground motions is also discussed.
