Acceleration‐Based Design Procedure for Sloped Rolling‐Type Bearings with an Added Rotational Inerter

Structural Control and Health Monitoring, Volume 2023, Issue 1, 2023., 2023
This research numerically investigates the mechanical behavior of sloped rolling‐type bearings equipped with an inerter. After deriving equations of motion, the mechanical behavior, under harmonic excitation, of a sloped rolling‐type bearing with its inherent rotational mass (i.e., considering the inertial and restoring forces generated by the existing

A Double‐Tuned Pendulum Mass Damper Employing a Pounding Damping Mechanism for Vibration Control of High‐Rise Structures

Structural Control and Health Monitoring, Volume 2023, Issue 1, 2023., 2023
Recently, enhancing conventional tuned mass dampers (TMDs) with a pounding damping mechanism is demonstrated to be an efficient way for vibration control of flexible structures. In this paper, a double‐tuned pendulum mass damper employing a pounding damping mechanism (DTPMD‐PD) is proposed.

Optimal design and performance assessment of multiple tuned mass damper inerters to mitigate seismic pounding of adjacent buildings [PDF]

, 2022
This work investigates the efficiency of tuned inerter dampers (TIDs) in controlling seismic response of two adjacent buildings and the pounding distance between them. Pervious research on this subject has shown that installing TIDs in every floor of one

Optimal Seismic Response Control of Adjacent Buildings Coupled with a Double Mass Tuned Damper Inerter

, 2022
Adjacent buildings are exposed to a high risk of pounding against each other during seismic events. In recent strong earthquakes events, the separation gap has been found to be insufficient to prevent structural damage related to pounding phenomena.

Concept, Tests, and Optimum Design of Novel Negative Stiffness Friction Dampers for Seismic Protection of Long‐Span Bridges

Earthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT Viscous dampers (VDs) are widely used to mitigate the excessive responses of long‐span bridges. However, VDs face some intricate challenges in engineering practices, including high damping coefficient requirement, potential base shear amplification and tremendous damping force under high velocity. To address these issues, this study develops a

Structural Health Monitoring of a Unidirectional Isolation Bridge: Bidirectional Seismic Behavior, Stochastic Model Updating, and Prediction

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 3, Page 759-780, March 2026.
ABSTRACT Accurate mechanical characterization of civil engineering structures after construction remains challenging due to the unique complexities of each structure, including geometric configurations, imperfect design modeling assumptions, soil conditions, and pervasive uncertainties in actual operational environments. Leveraging actual measurements,

Neuro‐Immune Crosstalk: Molecular Mechanisms, Biological Functions, Diseases, and Therapeutic Targets

MedComm, Volume 7, Issue 2, February 2026.
Neurons, immune cells, and other cellular components within the disease microenvironment (such as stromal cells and tumor cells) constitute a dynamically evolving ecosystem. Neurons directly modulate immune cell activity and inflammatory responses through the release of neurotransmitters (e.g., norepinephrine and CGRP), while also promoting tumor ...

Wind-induced vibration control of power transmission tower using pounding tuned mass damper [PDF]

, 2015
Wind-induced vibration control of power transmission tower using pounding tuned mass damper is studied in the paper. The power transmission tower, which is often a high and flexible structure, is very susceptible to wind-induced vibrations. To reduce the

Role Of Tuned Mass Dampers (Tmds) For Seismic Pounding Mitigation

International Journal of Environmental Sciences
During earthquakes, buildings that are too close together may crash into each other because there aren't enough gaps between them. This is called seismic bashing. This effect can cause serious damage to structures, which can put people's safety and the ability of things to work at risk.
