Response of buildings to near-field pulse-like ground motions

Earthquake Engineering and Structural Dynamics, 1999
Ground motions affected by directivity focusing at near-field stations contain distinct pulses in acceleration, velocity, and displacement histories. For the same Peak Ground Acceleration (PGA) and duration of shaking, ground motions with directivity pulses can generate much higher base shears, inter-storey drifts, and roof displacements in high-rise ...

Decomposition and Effects of Pulse Components in Near-Field Ground Motions

Journal of Structural Engineering, 2010
Long-period pulse components in near-field ground motions have been known to cause significant damage to flexible structures. In this paper, an empirical mode decomposition (EMD) approach is used to identify and separate the dominant pulse, high-frequency, and long-period components in near-field ground motions.

Nonlinear seismic response of mid-rise modular buildings subjected to near-field ground motions [PDF]

Journal of Constructional Steel Research, 2023
In recent earthquakes, structures near seismic sources have suffered severe damage due to near-fault ground motions. When compared with ordinary ground motions, these ground motions create high demands on structures. The presence of a strong energy pulse

Displacement and Acceleration Response Spectra for Near Field Strong Ground Motions

, 2002
Generation of a smoothed design response spectra is essential for practical seismic design. This project presents the results of a statistical regression analysis on displacement and acceleration response spectra for near-field strong ground motion earthquake events.

Response of middle-rise steel frames with and without passive dampers to near-field ground motions

Engineering Structures, 2003
This study analyses the response of middle-rise (6-stories) steel moment-resisting frame (MRF) with rigid joints subjected to near-field ground motions and also to artificial motions based on equivalent pulses.

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 ...

Stochastic model for simulation of near-fault ground motions [PDF]

Earthquake Engineering and Structural Dynamics, 2017
A parameterized stochastic model of near-fault ground motion in two orthogonal horizontal directions is developed. The major characteristics of recorded near-fault ground motions are represented.

Near-Field Across-Fault Seismic Ground Motions

Bulletin of the Seismological Society of America, 2011
Abstract There are many engineering applications that require an understanding of the nature of strong ground motions adjacent to and spanning across faults. Unfortunately, such near-field observations at distances less than 100 m of fault rupture are few and incomplete.

Simulation of Near-Field Pulse-Like Ground Motion

2012
The accurate prediction of ground motions from possible future earthquakes is the first step toward the robust assessment and mitigation of structural damage against earthquake hazards. The modeling of critical or resonant ground motions has been developed by the present authors in several studies.
