Pulse-like ground motion simulation using wavelet-based Hilbert transforms [PDF]

open access: yesمهندسی عمران شریف, 2022
In areas near active faults, ground motions usually show a large pulse in velocity time history. These near-field pulse-like ground motions increase the structural failure and cause extensive damage to structures.

Determining the Optimal Scalar Intensity Measure of Floor Communication Towers

open access: yesShock and Vibration, 2022
Various structural types and ground motion characteristics lead to distinct intensity measures of structural seismic performance. For the lattice high-rise steel structure of communication towers, determining the intensity measures to adjust ground ...

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 ...

Seismic performance of frame‐bent structures subjected to near‐fault ground motions

open access: yesThe 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 ...

Effects of the Predominant Pulse on the Inelastic Displacement Ratios of Pulse-Like Ground Motions Based on Wavelet Analysis

open access: yesAdvances in Civil Engineering, 2021
Having a predominant pulse is the main feature for pulse-like ground motions differing from others. To investigate the influence of the predominant pulse on the inelastic displacement ratios of pulse-like ground motions, the wavelet analysis method is ...

Method for Ranking Pulse-like Ground Motions According to Damage Potential for Reinforced Concrete Frame Structures

open access: yesBuildings, 2022
To rank the pulse-like ground motions based on the damage potential to different structures, the internal relationship between the damage potential of pulse-like ground motions and engineering demand parameters (EDPs) is analyzed in this paper.

Energy-based response prediction of reinforced concrete buildings with steel damper columns under pulse-like ground motions

open access: yesFrontiers in Built Environment, 2023
The response of structures under pulse-like ground motions is characterized by the large amount of energy input in a few cycles. Consequently, structures with insufficient strength may suffer severe damage owing to excessive deformation.
