Critical response of a single-degree-of-freedom system with bilinear hysteresis and viscous damping under triple impulse

open access: yesFrontiers in Built Environment
A triple impulse is used as a mathematical model of forward-directivity inputs, which are fault-normal components of near-fault earthquake ground motions. In this paper, two types of the triple impulse input are employed.

Nonlinear Dynamics of a Vibratory Cone Crusher with Hysteretic Force and Clearances

open access: yesShock and Vibration, 2011
Based on the analysis on crushing process and hysteresis of material layers, a hysteretic model with symmetrical clearances is presented. The mechanical model of two-degree of freedom with bilinear hysteresis and its dynamical equations of system are ...

Behaviour Investigation of SMA-Equipped Bar Hysteretic Dampers Using Machine Learning Techniques

open access: yesApplied Sciences, 2021
Most isolators have numerous displacements due to their low stiffness and damping properties. Accordingly, the supplementary damping systems have vital roles in damping enhancement and lower the isolation system displacement. Nevertheless, in many cases,

Computational modeling of yielding octagonal connection for concentrically braced frames [PDF]

open access: yesИнженерно-строительный журнал, 2020
Ductility is a feature which allows a structure to undergo large plastic deformations without any strength loss. Yield dampers are energy dissipation devices which increase the ductility and control the vibration of structures by absorbing earthquake ...

Critical Response of Nonlinear Base-Isolated Building Considering Soil-Structure Interaction Under Double Impulse as Substitute for Near-Fault Ground Motion

open access: yesFrontiers in Built Environment, 2018
The critical nonlinear response considering soil-structure interaction is investigated for a base-isolated building under a double impulse as a substitute for near-fault earthquake ground motions.

Helical single-walled carbon nanotubes under mechanical and electrostatic loading

open access: yesCarbon Trends, 2022
Here, we characterize the axial response of helical single-walled carbon nanotubes (HSWCNTs) to mechanical and electrostatic loads, separately. The study considers low-pitch (closed) and high-pitch (open) HSWCNTs of different number of turns in their ...

A tensor network study of the complete ground state phase diagram of the spin-1 bilinear-biquadratic Heisenberg model on the square lattice [PDF]

open access: yes, 2017
Using infinite projected entangled pair states, we study the ground state phase diagram of the spin-1 bilinear-biquadratic Heisenberg model on the square lattice directly in the thermodynamic limit.

Collapse-Limit Input Level of Critical Double Impulse for Damped Bilinear Hysteretic SDOF System With Negative Post-yield Stiffness

open access: yesFrontiers in Built Environment, 2019
The collapse-limit input velocity level of the critical double impulse simulating the principal part of near-fault ground motions is derived for an elastic-plastic structure with viscous damping and P-delta effect.

The Influence of Wind Direction on the Inelastic Responses of a Base-Isolated Square Section High-Rise Building

open access: yesBuildings, 2022
Previous studies show that the largest wind-induced response of a square section fixed-base high-rise building occurs when the strong wind is blowing perpendicular onto a building face, and the greatest translational response is likely to occur in the ...
