Analysis on Wind-Induced Vibration Dynamic Responses of Transmission Tower-Line System
Applied Mechanics and Materials, 2013Tower-line system of overhead transmission line are sensitive to wind. Therefore, dynamic effect of wind load should be taken into consideration, for instance, wind-induced vibration coefficient. There might be some errors in the calculation of the coefficient in accordance with ‘Load code for the design of building structures’, for its ignoring the ...

Analysis of Wind-Induced Vibration Response for a Long-Span Double-Arch-Support Steel Structure
Applied Mechanics and Materials, 2014As 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.

Journal of Wind Engineering and Industrial Aerodynamics, 2008
The aim of this study was to develop a hybrid vibration experiment system that can evaluate the performance of complicated vibration dampers, e.g. sloshing dampers, which show high nonlinearity. To this end, a system consisting of a computer and an actuator was developed, and applied to an experiment on a building with a tuned mass damper under wind ...

Wind Tunnel Study on Wind-Induced Vibration Responses of a UHV Transmission Tower-Line System
Advances in Structural Engineering, 2013This 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 ...

Transient Evaluation of Wind‐Induced Vibration Response of Heliostat Under Downburst
Energy Technology, 2023As the region with the highest amount of solar radiation, Qinghai–Tibet Plateau has the highest frequency of thunderstorms in China. Downburst generated in thunderstorm can cause high‐intensive wind near the ground, which is a critical threat to heliostats.

Study on Wind-Induced Vibration Response of Aerial Working Arm
Advanced Materials Research, 2012Since boom-type aerial equipment has complex dynamic characteristic under the action of random wind loads, traditional methods are hard to reflect its dynamic response. We put forward an analysis method for wind-induced random vibration response of aerial working arms based on finite element and pseudo-excitation methods.

The evaluation of wind‐induced vibration responses to a tapered tall building
The Structural Design of Tall and Special Buildings, 2007AbstractThe mitigation of wind‐induced excitations of tall buildings was investigated. The shape of a building can be aerodynamically modified by changing the taper of the cross‐section. This modification alters the flow pattern around the building, and reduces wind‐induced vibration of tall buildings.

Study on Vertical Wind-Induced Vibration Response for Portal Frame Structures
Applied Mechanics and Materials, 2011In recent years, as the portal frame’s height toward higher and the span toward wider, the influence of wind vibration becomes more and more prominent among the portal frame structure. In the design of the portal frame, there are many different opinions on whether considering the impact of the vertical wind vibration to the portal frame.

Dominant Modals of Wind-Induced Vibration Response for Spherical Kiewitt Cable Dome
Advanced Materials Research, 2014Correlation coefficients of mode shape between higher frequency modes and lower frequency modes are given. Then 17 high modes were initially selected as the dominant high modes in the analysis of wind-induced response, and cumulative mode correlation was used to judge the rationality of the method of selecting dominant high modals, so dominant modals ...
