Study of Rotational Ground Motion in the Near-Field Region
Bulletin of the Seismological Society of America, 2009 During the nineteenth and twentieth centuries observational seismologists recorded primarily the earthquake-induced translational wave field, while the rotational motion still remains poorly observed and investigated. We aim to further understand the rotational ground motion and its relation to the translational wave field, with a special emphasis on ...

Seismic Performance of Midstory Isolated Structures under Near-Field Pulse-Like Ground Motion and Limiting Deformation of Isolation Layers [PDF]
Shock and Vibration, 2015 Excessive deformation of the isolation layer in midstory isolated structures may occur under strong near-field pulse-like ground motion, which would result in the overturning collapse of the superstructure.

Baseline correction for near-fault ground motion recordings of the 2008 Wenchuan Ms8.0 earthquake
Geodesy and Geodynamics, 2012 In this study, both records of a digital accelerometer and a seismograph at a far-field station for the 2008 Ms8.0 Wenchuan earthquake were analyzed, and a pulsive noise model for acceleration record was found.

Investigating the Correlation between the Parameters of Ground Motion Intensity Measures for Iran's Data [PDF]
Journal of Soft Computing in Civil Engineering, 2022 This paper presents a statistical correlation analysis of peak ground acceleration to peak ground velocity ratio (A/V) and other ground motion intensity measures (IMs) for Iran’s data. A/V is an important parameter that can significantly affect nonlinear

Investigation of Uplift force effects on Seismic Damage of Concrete Gravity Dam in the Near-Fault and Far-Fault Ground Motions:Case Study Shafaroud Dam [PDF]
Journal of Structural and Construction Engineering, 2019 Uplift force has significant role on dynamic response of concrete gravity dams and also seismic response of dams in near field motion can be considerably different from those observed in the far field and the near –fault ground motions can cause ...

Seismic performance of frame‐bent structures subjected to near‐fault ground motions
The Journal of Engineering, 2021 Reinforced concrete frame‐bent structures are one of the structural forms commonly used in industrial factory buildings. In order to study the seismic behaviour of frame‐bent structures located near fault areas, eight pulse‐like, eight non‐pulse near ...

Near-field horizontal and vertical earthquake ground motions [PDF]
Soil Dynamics and Earthquake Engineering, 2003 Strong-motion attenuation relationships are presented for peak ground acceleration, spectral acceleration, energy density, maximum absolute input energy for horizontal and vertical directions and for the ratio of vertical to horizontal of these ground motion parameters. These equations were derived using a worldwide dataset of 186 strong-motion records
