Representation of near-fault pulse-type ground motions

Earthquake Engineering and Engineering Vibration, 2005
Near-fault ground motions with long-period pulses have been identified as critical in the design of structures. To aid in the representation of this special type of motion, eight simple pulses that characterize the effects of either the fling-step or forward-directivity are considered.

Simulation analysis of TMD controlled building subjected to far- and near-fault records considering soil-structure interaction

Journal of Building Engineering, 2019
This study aims to investigate the performance of a tuned mass damper (TMD) in mitigating the dynamic response of buildings to far- and near-fault earthquake records including soil–structure interaction (SSI) effects.

A Mathematical Representation of Near-Fault Ground Motions

Bulletin of the Seismological Society of America, 2003
A simple, yet effective, analytical model is proposed for the representation of near-field strong ground motions. The model adequately describes the impulsive character of near-fault ground motions both qualitatively and quantitatively. In addition, it can be used to analytically reproduce empirical observations that are based on available near-source ...

Seismic fragility assessment of a multi-span RC bridge in Bangladesh considering near-fault, far-field and long duration ground motions

Structures, 2019
Seismic vulnerability of a three-span continuous highway bridge located in Kishoreganj, Bangladesh is assessed numerically in this study. Fragility curves have been derived from the nonlinear incremental dynamic analysis results of the bridge subjected ...

Performance of sliding systems under near-fault motions

Nuclear Engineering and Design, 2001
Response of structures supported on the sliding systems under near-fault earthquake ground motion is investigated. The fault normal and parallel components are applied in two horizontal direction of the system. The superstructure is considered to be rigid and the frictional forces mobilized at the interface of the sliding system are assumed to be ...

Reliability of semi-active seismic isolation under near-fault earthquakes

Mechanical systems and signal processing, 2019
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.

Nonlinear seismic responses of the powerhouse of a hydropower station under near-fault plane P-wave oblique incidence

Engineering structures, 2019
Near-fault ground motion has unique motion characteristics that are mainly manifested as long periodic velocity and large displacement pulses. Engineering structures in near-fault areas are frequently damaged severely.

Reversed-Polarity Secondary Deformation Structures Near Fault Stepovers

Journal of Applied Mechanics, 2012
We study volumetric deformation structures in stepover regions using numerical simulations and field observations, with a focus on small-scale features near the ends of rupture segments that have opposite-polarity from the larger-scale structures that characterize the overall stepover region. The reversed-polarity small-scale structures are interpreted
