Dynamic responses and vibration control of the transmission tower-line system: a state-of-the-art review. [PDF]
This paper presented an overview on the dynamic analysis and control of the transmission tower‐line system in the past forty years. The challenges and future developing trends in the dynamic analysis and mitigation of the transmission tower‐line system under dynamic excitations are also put forward.

Large megawatts offshore wind turbine (OWT) with low natural frequency and low damping is subjected to significant vibration from wind and wave actions in its service environment. The one‐dimensional prestressed tuned mass damper (PSTMD) is further extended to a 3D‐PSTMD for the control of vibrations of the OWT in this paper.

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

Seismic Vibration Mitigation of a Cable‐Stayed Bridge with Asymmetric Pounding Tuned Mass Damper
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

Vibrations due to mechanical excitation and internal and external fluid flow can cause fatigue in pipelines and leaks in fittings. A beam‐based dynamic vibration absorber (beam DVA) is a device comprising an L‐shaped beam with a concentrated mass at its free end that can be used to absorb and dissipate vibrations in the pipeline.

Development of a Frequency‐Adjustable Tuned Mass Damper (FATMD) for Structural Vibration Control
The tuned mass damper (TMD) can be applied to suppress earthquake, wind, and pedestrian‐ and machine‐induced vibration in factory buildings or large span structures. However, the traditional TMD with a fixed frequency will not be able to perform effectively against the frequency variations in multiple hazards. This paper proposed a frequency‐adjustable

The voided biaxial concrete slab has been widely used in the engineering field. The slab has become a popular choice for designers and architects looking to reduce slab thickness and overall structure weight recently. Utilizing the empty space in the voided slab and introducing the structural control technology of mass damper into it, a new pounding ...

An Updated Analytical Structural Pounding Force Model Based on Viscoelasticity of Materials
Based on the summary of existing pounding force analytical models, an updated pounding force analysis method is proposed by introducing viscoelastic constitutive model and contact mechanics method. Traditional Kelvin viscoelastic pounding force model can be expanded to 3‐parameter linear viscoelastic model by separating classic pounding model ...

Parametric Study of Tuned Mass Dampers for Long Span Transmission Tower‐Line System under Wind Loads
A parametric study of tuned mass dampers for a long span transmission tower‐line system under wind loads is done in this paper. A three‐dimensional finite element model of transmission tower‐line system is established by SAP2000 software to numerically verify the effectiveness of the tuned mass damper device.
