Wind-Induced Vibrations in the European Court Towers
Issues regarding occupancy comfort in vibration-sensitive structures are the motivation of this study concerning wind-induced vibrations in the European Court Towers in Luxembourg. In one of the two identical towers tuned liquid dampers (TLD) have been installed.Hansen, Jannick Balleby +4 more

Rain-wind induced vibration of cables
Journal of Wind Engineering and Industrial Aerodynamics, 1995Full 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.

Spectral Approximation for Wind Induced Structural Vibration Studies
Meccanica, 1998The 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.

Fuzzy sliding surface control of wind-induced vibration
2014 IEEE International Conference on Fuzzy Systems (FUZZ-IEEE), 2014Although 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.

Control of wind-induced vibrations of cable-stayed bridges
Journal of Wind Engineering and Industrial Aerodynamics, 1983Abstract 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, 2008Increasing 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
2007Modern 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.
