An isolation device for near-fault ground motions
Structural Control and Health Monitoring, 2013 Seismic isolation is an appreciable control strategy that reduces the vibrations of structural and nonstructural systems induced by strong ground motions. However, under near-fault (NF) ground motion, the seismic isolation devices might perform poorly because of large isolator displacements caused by long-period large velocity and displacement pulses ...

Seismic responses of isolated bridges subjected to near-fault ground motions: simple pulses vs. whole records [PDF]
Frontiers in Built EnvironmentVelocity pulse with strong energy input is the significant feature of near-fault ground motions. Bridges close to or passing across seismic faults may suffer from higher failure risk, which is inseparable from the influence of velocity pulse.
