The response of Karnali Bridge, Nepal to near-fault earthquakes
Proceedings of the Institution of Civil Engineers - Bridge Engineering, 2012Seismic records during recent destructive earthquakes such as Northridge (1994), Kobe (1995), Duzce (1999) and Chi-Chi (1999) revealed peculiarities of ground motion near active faults. Those earthquakes indicated that the vertical acceleration can reach values comparable to horizontal acceleration or may even exceed these accelerations.

Multifractal characteristic analysis of near-fault earthquake ground motions
Soil Dynamics and Earthquake Engineering, 2015Abstract This study aims to reveal the multi-scaling behavior and quantify the irregularity of near-fault earthquake ground motions from a new perspective of multifractal theory. Based on multifractal detrended fluctuation analysis, the multifractal characteristic parameters of acceleration time series for typical near-fault ground motions are ...

Near-Fault Baseline Correction Method and Appliction in Wenchuan Earthquake
Applied Mechanics and Materials, 2012To eliminate the drifting in recordings from Ms8.0 Wenchuan earthquake, a modified two segments baseline correction method is brought up and systematic acceptance standard is presented. The method is applied to recordings from Qingping station and Bajiao station, which are closest stations to surface rupture traces. The effect of baseline correction on

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.

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 ...

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.

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.

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 ...
