Numerical investigation of ground tanks for storage subjected near-fault earthquakes
Pollack Periodica, 2021Abstract Finite element method is known as the most common methods in a numerical analysis of reservoirs subjected to the influence of an earthquake. Investigating the effects of interaction between structures and fluid during the earthquake is among the major objectives of the present research.

Performance of TMDs on nonlinear structures subjected to near-fault earthquakes
Smart Structures and Systems, 2015Tuned mass dampers (TMD) are devices employed in vibration control since the beginning of the twentieth century. However, their implementation for controlling the seismic response in civil structures is more recent. While the efficiency of TMD on structures under far-field earthquakes has been demonstrated, the convenience of its employment against ...

Effect of near-fault earthquakes with forward directivity on telecommunication towers
Earthquake Engineering and Engineering Vibration, 2011In this paper, the effect of pulse-type motions caused by forward directivity that can release huge amounts of energy in a short time period is studied on a telecommunication tower. Since telecommunication towers have longer periods, they are not as affected by seismic forces.

Behavior of Quintuple Friction Pendulum System Under Near-Fault Earthquakes
Journal of Earthquake and Tsunami, 2017The Quintuple Friction Pendulum (QTFP) system is a new generation sliding isolation having six spherical sliding surfaces with five effective pendula. Due to multiple sliding surfaces, QTFP system shows highly adaptive behavior under different hazard level of earthquakes, despite being a passive system.

Effect of near-fault earthquakes on North American nuclear design spectra
Nuclear Engineering and Design, 2006Ground motion records from recent earthquakes show that near-fault ground motions are different from far-field ground motions in that they often contain strong coherent dynamic long period pulses and permanent ground displacements. The objective of the current study is to assess the safety implications of near-fault earthquakes (NFE) on nuclear power ...

Aseismic design implications of near‐fault san fernando earthquake records
Earthquake Engineering & Structural Dynamics, 1978AbstractNear‐fault records of the 1971 San Fernando earthquake contain severe, long duration acceleration pulses which result in unusually large ground velocity increments. A review of these records along with the results of available theoretical studies of near‐fault ground motions indicates that such acceleration pulses may be characteristic of near ...

Reliability of semi-active seismic isolation under near-fault earthquakes
Mechanical Systems and Signal Processing, 2019Abstract Structural control can be used for protecting buildings and its vibration-sensitive contents from earthquakes. Seismic isolation is a passive control system that lowers effective earthquake forces by utilizing flexible bearings. However, supplemental damping in the isolation system may become necessary to reduce large isolator displacements ...

EARTHQUAKE RESISTANT DESIGN OF STRUCTURES IN NEAR-FAULT REGIONS
Structures designed by conventional method of earthquake resistant design and built in near-fault (NF) regions are vulnerable to the distinctly different characteristics of NF earthquake strong ground motions¸ which are not considered in conventional earthquake hazard estimation.openaire +1 more source
Near-Fault Peak Ground Velocity from Earthquake and Laboratory Data
Bulletin of the Seismological Society of America, 2007We test the hypothesis that peak ground velocity (pgv) has an upper bound independent of earthquake magnitude and that this bound is controlled primarily by the strength of the seismogenic crust. The highest pgvs, ranging up to several meters per second, have been measured at sites within a few kilometers of the causative faults.
