Identification of Near-Fault Impulsive Signals and Their Initiation and Termination Positions with Convolutional Neural Networks

Geosciences, 2021
Ground motions recorded in near-fault regions may contain pulse-like traces in the velocity domain. Their long periodicity can identify such signals with large amplitudes.

Correlation analysis between ground motion parameters and seismic damage of buildings for near-field ground motions

Natural Hazards Research, 2022
Pulse-like ground motions constitute a significant challenge to the performance of buildings, as they are characterized by long intense velocity, displacement, or acceleration pulses.

Seismic Performance of Midstory Isolated Structures under Near-Field Pulse-Like Ground Motion and Limiting Deformation of Isolation Layers

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.

A non-separable stochastic model for pulse-like ground motions [PDF]

, 2014
A phenomenological non-separable non-stationary stochastic model is proposed to represent near-fault pulse-like ground motions (PLGMs) by means of a parametrically defined evolutionary power spectrum (EPSD). Numerical data pertaining to ensembles of EPSD compatible realizations and considering statistical analysis of peak elastic and inelastic spectral

The Effect of Ground Motion Selection Methods for Seismic Design of Tall Buildings: A Case Study of Mandalay City

Walailak Journal of Science and Technology, 2020
The near-fault earthquakes ground motion usually observed a few kilometers away from the active faults generally contains high energetic velocity pulses as a consequence of directivity effects.

Tuned Mass Dampers for Response Reduction of a Reinforced Concrete Chimney Under Near-Fault Pulse-Like Ground Motions

Frontiers in Built Environment, 2020
The article investigates response mitigation of a reinforced concrete (RC) chimney subjected to pulse-like near-fault ground motions using tuned mass damper (TMD) schemes. The total height of the chimney is 265 m with a mass of 11,109 ton.

Recurrent neural network-based seismic slope displacement hazard assessment considering the effects of slope aspects

Geomatics, Natural Hazards & Risk
Directionality of ground motion with respect to faulting is crucial if directivity pulse-like effects are observed; as a result, ground motion along slope sliding directions with pulse-like effects has a significant impact on slope stability during ...

Inelastic displacement ratio for rocking buildings subjected to far-field and near-field pulse-like ground motions [PDF]

Journal of Structural and Construction Engineering, 2019
Self centering rocking buildings are capable of reducing permanent damage and concentrating damage to replaceable energy dissipation devices. This paper aims to calculate inelastic displacement ratio for self centering rocking buildings under far field ...

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations

FEBS Letters, EarlyView.
The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...
