Modeling of rain-wind induced vibrations

Wind and Structures, 2003
Rain-wind induced vibrations of cables are a challenging problem in the design of cable-stayed bridges. The precise excitation mechanism of the complex interaction between structure, wind and rain is still unknown. A theoretical model that is able to accurately simulate the observed phenomena is not available.

Wind-induced vibration of structural cables

Nonlinear Dynamics, 2020
The wind-induced vibration of cables has been widely studied over the past decades because of cables’ many applications in cable-stayed, suspension, and tied-arched bridges, and power transmission lines. They have been mostly investigated through research conducted on rigid model cables with a finite length and circular cross-sectional geometry that ...

Wind-induced vibrations

1995
This chapter deals with wind-induced structural vibrations from the point of view of structural engineering. Basically, no civil engineering structure is safe from wind loading effects. Of critical importance are the non-stationary characteristics of natural wind and the dynamic properties of the structure it acts upon.

Experimental Assessment of Wind‐Induced Vibrations

Journal of Engineering Mechanics, 1987
The present study is initiated to investigate the possible causes for excessive lamp failure rates on high‐mast illumination towers in the state of Minnesota. The study consists of an experimental effort during which one of the illumination towers is instrumented and motion data is collected for various wind conditions.

Wind-induced vibrations of nonsymmetrical structures

Journal of Wind Engineering and Industrial Aerodynamics, 1996
Even high slender structures of beam type, like masts, do not always deflect in the same plane as the loading acts. The nonsymmetry of the cross-section or imperfections of the material evoke a combined response in space. Torsion can occur too: it can be coupled with the bending through the guy supports, if the forces in windward and leeward guys of ...

Conversion of wind-induced vibrations into electricity

2014 IEEE 36th International Telecommunications Energy Conference (INTELEC), 2014
The recently growing concern to reduce the energy from non-renewable sources encourages the development of new energy harvesting methods. In case of unattended remote telecom equipment, it should be advantageous to obtain energy from the wind while no rotation is applied.

Wind Induced Vibration in Light Poles

Journal of the Structural Division, 1970
Modal analysis is applied to obtain a solution to the differential equations of motion of a vibrating cantilevered light pole when subjected to wind forces. Use is made of a high-speed computer in the solution processes. The excitation forces are those caused by vortices which are shed alternately along the cylindrical portion of the vertical support ...

Wind Induced Vibration of Cylindrical Structures

Journal of the Engineering Mechanics Division, 1957
With reference to problem of designing tall stacks wind tunnel investigations were made to determine dynamic behavior of cylindrical sections under action of wind at high Reynold's numbers; results show that wind induced vibration normal to direction of wind is self excited rather than forced; basic aerodynamic phenomenon associated with higher ...

Practical experiences with wind-induced vibrations

Journal of Wind Engineering and Industrial Aerodynamics, 1990
Abstract A refined engineering model for the estimation of vortex-induced vibrations slender stuctures is briefly presented. Experiences with this model in relation to full-scale observations are shown within three different examples. The first example is related to steel stacks, the second describes the experience with bridge hangers and its ...

Wind-induced vibrations of a facade element

Journal of Wind Engineering and Industrial Aerodynamics, 1983
Abstract A facade element of a hospital building was tested in the wind tunnel of the Federal Research Institute in Vienna. This element consisted of six main parts: the window, the window frame, the inspection walkway in front of the window, the console, the handrail of the walkway and the sunshades.
