In this paper, a simplified closed-form approximation using decaying sinusoids is proposed to model longperiod velocity pulses in near-fault ground motions. The objective of such formulation is to represent dominant kinematic characteristics of ground motions instead of modeling ground motions accurately since only the most prominent frequency component of such ground motions can be represented by the closedform approximation. The validity and usefulness of the proposed approximation is demonstrated using near-fault earthquakes measured during Northridge (1994) and Landers (1992) earthquakes.
