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.

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 ...

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 ...

Fuzzy sliding surface control of wind-induced vibration

2014 IEEE International Conference on Fuzzy Systems (FUZZ-IEEE), 2014
Although normal fuzzy sliding mode controllers can reduce the chattering problem in building structure control, there are some problems such as they need the equivalent control and the upper bounds of the uncertainties. In this paper, we use fuzzy logic to approximate the sliding surface for the sliding mode control.

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.

Control of wind-induced vibrations of cable-stayed bridges

Journal of Wind Engineering and Industrial Aerodynamics, 1983
Abstract The objective of this paper is to present new trends in the development of cable-stayed bridges and to review practicable control techniques concerning wind-induced vibrations. That contains the results of examinations carried out by the Institute of Light-Weight Structures of the Aachen Technical University and the DSD Dillinger Steel ...

Mitigation of Wind-Induced Vibration with Liquid Column Vibration Absorber

Advances in Science and Technology, 2008
Increasing heights of tall buildings often require supplementary damping system for occupant comfort in windy condition. This paper presents a liquid column vibration absorber (LCVA) installed in a 64-story building, which is the highest residential building with flat plate structural system in Korea, for mitigation of wind-induced motion.

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.
