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 transmission line system

Journal of Wind Engineering and Industrial Aerodynamics, 1992
Abstract This paper describes results of a full-scale measurements and a time series analysis for the wind-induced vibration of a transmission line system. The time series analysis is based on a quasi-static assumption. The study is mainly discussed as in terms of the effects of the coupling motion between a steel tower and conductors.

Wind-induced random vibrations of structures

2007
Modern wind codes indicate calculational procedures which allow engineers to deal with structural systems which are susceptical to conduct wind excited oscillations. In the codes approximative formulas are specified which relate the dynamic problem to rather abstract parameter functions.

Spectral Approximation for Wind Induced Structural Vibration Studies

Meccanica, 1998
The authors discuss the prediction of the response of structural systems to wind loads. The solution is obtained by using modal coordinates. In order to evaluate the stochastic structural response of considered multi-degree-of-freedom linear systems, it is necessary to calculate the corresponding spectral moments.

Wind-Induced Vibration of Tubular Diagonals of the Werkspoorbridge

Structural Engineering International, 2004
Vibrations were recorded two months after the completion of the Werkspoorbridge in Utrecht, The Netherlands, during heavy winds. The vibrations were due to excitation generated by von Karman vortices. The vibrations could lead to fatigue damage. In situ measurements were conducted to determine the natural frequency and the damping ratio of the diagonal

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 ...

Rain-wind induced vibration of cables

Journal of Wind Engineering and Industrial Aerodynamics, 1995
Full scale wind tunnel tests have been conducted on a section of the stays of the Normandie Bridge. Climatic and dynamic exact characteristics of the rain-wind induced excitation have been reproduced and the phenomenon identified with standard polyethylene cylindrical smooth casing.

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.
