Abstract

Most of the megacities are located near the active faults. Ground motions in the vicinity of the active faults are associated with two main phenomena so called rupture directivity and fling effects. Therefore, it is important for earthquake resistance design and seismic hazard mitigation to evaluate the characteristics of near-fault ground motions in the megacities. In this paper, the near-fault ground motion was simulated using kinematic model for Tehran City, the capital of Iran. Tehran city was developed along the North Tehran Fault (NTF), which assumed to be the most probable seismic source for the city. Kinematic models are efficient tools to simulate long-period ground motions including slip heterogeneity (Asperities) on the fault and underground geology. Here, the near-fault ground motions are generated assuming NTF scenario using kinematic finite fault model. Then, the variations of faulting parameters such as rise time, maximum slip, rupture velocity, and site to fault distance on the near-fault pulse characteristics are numerically examined and discussed.
