Relation Between Near‐Fault Ground Motion Impulsive Signals and Source Parameters [PDF]
AbstractNear‐fault ground motion records often present impulsive signals, characterized by a large amplitude in the velocity wavefield and by the energy concentrated in a short time window as compared to the total earthquake duration. This pulse‐like behavior is ascribed to the directivity of the seismic rupture, and it requires a stronger demand to ...

The velocity pulse contained in near-fault ground motions have a tremendous impact on dam safety. Previous studies have mainly focused on the response of dams under near-fault seismic records without considering the obliquely incident seismic waves.

Local and global effects of forward directivity
Previous studies have revealed that near-fault ground motions perpendicular to the fault slip are very destructive for structures. Due to the common use of moment resisting frames and the importance of near-fault strong motions, the local and global ...

Evaluation of seismic parameters of steel moment resisting frames based on “FEMA P-695” under near-field rotated ground motion [PDF]
Behavior factor (R) is one of the seismic design parameters that considers nonlinear performance of structures during an earthquake. In most of the seismic design codes, behavior factor has been used for considering nonlinear performance of structures in

Estimation of Near-Fault Strong Ground-Motion
Accumulated data of strong ground motions have been providing us very important knowledge about rupture processes of earthquakes, propagation-path, site-amplification effects on ground motion, the relation between ground motion and damage... However, most of the ground motion databases used in the development of ground motion prediction models are ...

Variable friction pendulum system for near-fault ground motions
The seismic response of a flexible multi-storey building isolated with variable friction pendulum system (VFPS) is investigated under normal component of six near-fault ground motions. The VFPS, an advanced friction base isolator, is proposed in this study.

Seismic damage analysis due to near‐fault multipulse ground motion
AbstractNear‐fault pulse‐like ground motion is a significant class of seismic records since it tends to cause more severe damage to structures than ordinary ground motions. However, previous researches mainly focus on single‐pulse ground motions. The multipulse ground motions that exist in records receive rare attention.
