Dynamic Response Evaluation of Bridges Considering Aspect Ratio of Pier in Near-Fault and Far-Fault Ground Motions

open access: yesApplied Sciences, 2020
The recent increase in earthquake activities has highlighted the importance of predicting the seismic response of structures. Damage to civil infrastructure, particularly bridges, can cause considerable human and property losses.

Application of BRB to Seismic Mitigation of Steel Truss Arch Bridge Subjected to Near-Fault Ground Motions

open access: yesBuildings, 2022
In this paper, the seismic response of a steel truss arch bridge subjected to near-fault ground motions is studied. Then, the idea of applying buckling restrained braces (BRBs) to a steel truss arch bridge in near-fault areas is proposed and validated ...

Synthetic Ground-Motion Simulation Using a Spatial Stochastic Model with Slip Self-Similarity: Toward Near-Source Ground-Motion Validation

open access: yesTerrestrial, Atmospheric and Oceanic Sciences, 2016
Near-fault ground motion is a key to understanding the seismic hazard along a fault and is challenged by the ground motion prediction equation approach. This paper presents a developed stochastic-slip-scaling source model, a spatial stochastic model with

The 3D numerical simulation of near-source ground motion during the Marsica earthquake, central Italy, 100 years later [PDF]

open access: yes, 2015
In this paper we show 3D physics-based numerical simulations of ground motion during one of the most devastating earthquakes in the recent Italian history, occurred on Jan 13, 1915, Marsica, Central Italy.

A three-dimensional dislocation model for the San Fernando, California, earthquake of February 9, 1971 [PDF]

open access: yes, 1974
The data from five strong-motion accelerograph stations centered above and surrounding the fault are used to develop an approximate three-dimensional dislocation model for the San Fernando earthquake.

Seismic Fragility Assessment of Steel SMRF Structures under Various Types of Near and Far Fault Ground Motions [PDF]

open access: yesJournal of Rehabilitation in Civil Engineering, 2019
In this paper, the seismic collapse probability of special steel moment-resisting frame (SSMRF) structures, designed to 4th edition of Iranian seismic design code, under near fault pulse-like and far fault ordinary ground motions is evaluated through ...

Near-Source Ground Motions from Simulations of Sustained Intersonic and Supersonic Fault Ruptures [PDF]

open access: yes, 2004
We examine the long-period near-source ground motions from simulations of M 7.4 events on a strike-slip fault using kinematic ruptures with rupture speeds that range from subshear speeds through intersonic speeds to supersonic speeds.

Quantitative Identification of Pulse-Like Ground Motions Based on Hilbert–Huang Transform

open access: yesShock and Vibration, 2021
Aiming to address the problem of pulse-like ground motions being difficult to identify, this paper refines the Baker’s wavelet-based pulse-like ground motions identification method, followed by a new pulse-like ground motion identification method based ...
