Seismic Vibration Mitigation of a Cable-Stayed Bridge with Asymmetric Pounding Tuned Mass Damper [PDF]

Mathematical Problems in Engineering, 2021
In order to mitigate the seismic response of a cable-stayed bridge, a new type damping device named asymmetric pounding tuned mass damper (APTMD) is developed in this paper on the basis of the traditional symmetric pounding tuned mass damper. The novel APTMD has three parameters to be determined: the left-side gap, the right-side gap, and the frequency

Reduction of Vibrations in Long‐Span Continuous Girder Bridges with Pounding Tuned Mass Dampers

Advances in Civil Engineering, 2022
Earthquakes often cause bridges to vibrate to different degrees; moreover, in the case of poor road conditions, the vibration amplitude of bridges caused by vehicles often exceeds a reasonable range, thus causing different degrees of damage to bridges.

Control Action of a Tuned Mass Damper in Mitigating Earthquake-Induced Structural Pounding Between Building Floors

, 2022
Passive control devices are widely used in the reduction of lateral vibrations of building structures. The control of these lateral vibrations is vital in preventing collisions between adjacent building structures during a seismic event. These collisions modify the dynamic behavior of the intervenient structures and cause substantial local damage.

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.

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

Earthquake Engineering &Structural Dynamics, Volume 55, Issue 11, Page 2719-2741, September 2026.
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

Enhancement of Seismic Resilience of Structures With Tuned Mass Damper Inerter by Using Effective Damping Ratio

Earthquake Spectra, Volume 42, Issue 3, August 2026.
This study investigates the performance of a tuned mass damper inerter (TMDI) in enhancing the seismic performance of structures by focusing on the concept of effective damping ratio (EDR) and its enhancement through the effective damping ratio enhancement (EDRE) approach. An analytical model is developed for a single‐degree‐of‐freedom system subjected

Disorder‐Driven Fast Na+ Transport: From Crystalline to Amorphous Networks in the Mixed‐Anion NaTaOxCl6−2x Oxychlorides

Advanced Energy Materials, Volume 16, Issue 24, 24 June 2026.
Oxygen substitution in NaTaOxCl6‐2x drives structural evolution from isolated [TaCl6]– octahedra, through oxygen‐bridged [Ta2OCl10]2– dimers, toward extended trans‐[TaO2Cl4]3– chain‐like arrangements. At intermediate compositions, zero‐dimensional corner‐sharing motifs are proposed to create a flexible, disordered framework that peaks ionic ...
