Local Structure Response of High-Rise Empty Cylindrical Shell Towers to Wind-Induced Resonance Vibration

ASME 2010 Pressure Vessels and Piping Conference: Volume 3, 2010
High-rise towers are very sensitive to wind loads because of their high flexibility. Wind-induced resonance vibrations due to Karman vortex street have great impact on these structures, especially for the high empty cylindrical shell towers. In a petrochemical enterprise, a few local cracks were detected in some empty towers and the wind-induced ...

Study on Wind Induced Vibration Response of High-voltage Disconnector Switch by Wind Tunnel Test

2020 IEEE 4th Conference on Energy Internet and Energy System Integration (EI2), 2020
The disconnector switch is highly sensitive to the wind load. Under the strong wind, such structure can have a huge wind-induced vibration, which may cause its destruction and result in the loss of the high-voltage substations. In order to study this vibration characteristic, the wind-tunnel test of the GW35-550 high voltage disconnector switch has ...

Analysis of Wind-Induced Vibration Response for a Long-Span Double-Arch-Support Steel Structure

Applied Mechanics and Materials, 2014
As a new long-span double-arch-support steel structure system is applied to a stadium, it is necessary to study the wind-induced vibration response of the roof structure to meet the need of design. The modal analysis and the response analyses which include static wind response and wind-induced vibration response are calculated by ANSYS.

Wind Tunnel Study on Wind-Induced Vibration Responses of a UHV Transmission Tower-Line System

Advances in Structural Engineering, 2013
This paper presents an experimental investigation on the wind-induced vibration of a transmission tower-line system. A discrete stiffness method is applied to design the aero-elastic model on the basis of similarity theory. The dynamic characteristics of the single tower and the tower-line system are identified and the displacement responses at ...

Vibration Modes Coupling Effect in the Wind-Induced Response of a Ribbon-Like Long Span Roof

Advanced Materials Research, 2011
The test conditions and main results of wind tunnel test for an exhibition hall and a stadium ribbon-like long span roof of a Sports Convention Center are introduced. We got the average and fluctuating wind pressures of the roof. Then we use typical points measuring method to analyze them. According to the energy contribution method, dominant modes are

Viscous-Tuned Hybrid Structural Vibration Mitigation System: Wind-Induced Response Analyses Method and Case Study

2019
The wind-induced vibrations of super tall buildings become excessive due to strong wind loads, super building height and high flexibility. Tuned mass dampers (TMDs) and viscous dampers have been widely used to control vibrations for actual super tall buildings for decades.

Wind-induced Vibration Response of Substation Pillar-type Switch Structures Based on Wind Tunnel Tests

International Journal of Structural Stability and Dynamics
To investigate the wind-induced vibration characteristics of the high-voltage disconnect switch (DS) system in the switching-off state andquantitatively evaluate the contribution of higher-order modes to the overall structural response, this study employed the finite element software ABAQUS to perform dynamic analysis of a refined finite element model ...
