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

Frontiers 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

Buildings, 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 ...

Critical Response of Single-Degree-of-Freedom Damped Bilinear Hysteretic System under Double Impulse As Substitute for Near-Fault Ground Motion

Frontiers in Built Environment, 2018
A double impulse input is used as a substitute for near-fault earthquake ground motions. An explicit expression is derived on the maximum elastic–plastic response of a single-degree-of-freedom damped structure with bilinear hysteresis under the “critical

Closed-form critical response of elastic-plastic shear building with viscous damper under pseudo-double impulse for simulating resonant response under near-fault fling-step motion

Frontiers in Built Environment, 2022
A set of approximate closed-form solutions of the maximum interstory drifts under the critical pseudo-double impulse (PDI) is derived for non-proportionally damped multi-story shear building models with bilinear hysteresis.

Modelling of Mechanical Behaviour of High-Frequency Piezoelectric Actuators Using Bouc-Wen Model

Metrology and Measurement Systems, 2017
The paper presents application of a modified, symmetrical Bouc-Wen model to simulate the mechanical behaviour of high-frequency piezoelectric actuators (PAs). In order to identify parameters of the model, a two-step algorithm was developed.

Dynamic analysis of dry friction system based on improved bilinear hysteretic model

Journal of Hebei University of Science and Technology, 2018
Considering that the dry friction force only shows stiffness characteristic when the normal contact force is high and combining with the existing conclusions of experimental research, the bilinear hysteresis model is improved.

Comparison of Vehicle Suspension Dynamic Responses for Simplified and Advanced Adjustable Damper Models with Friction, Hysteresis and Actuation Delay for Different Comfort-Oriented Control Strategies

Acta Mechanica et Automatica, 2023
Throughout the years, many control strategies for adjustable dampers have been proposed, designed to boost the performance characteristics of a vehicle. Comfort control strategies such as Skyhook (SH), acceleration-driven damping or power-driven damping ...
