Response Spectra of Structures under Subway Induced Vibrations
Passing underground trains induce vibrations transmitted to the ground surface and the nearby structures. Ordinarily, these vibrations do not result in structural damage but can harm nonstructural elements and disturb the occupants. These effects are more pronounced when evaluating buildings like hospitals, laboratories, museums, etc., and their assessment is an important design need. To respon...
متن کاملNumerical Investigation of Wind Induced Ovalling Vibrations in Silo Groups
Wind induced ovalling vibrations were observed during a storm in October 2002 on several empty silos of a closely spaced group consisting of 8 by 5 thin-walled silos in the port of Antwerp (Belgium). In the present study, it is investigated if the observed ovalling oscillations can be numerically predicted. To this end, the silo structures are modeled using a finite element (FE) model and the w...
متن کاملWind-structure interaction simulations of wind induced ovalling vibrations in silo groups
Wind induced ovalling vibrations have been reported to occur on several empty, flexible silo structures in group arrangement. The focus in this paper is on the numerical prediction of this phenomenon by simulating the wind flow around a single silo and taking into account the interaction of the wind flow with the structural response. The importance of the 3D turbulent wind flow and wake effects...
متن کاملInvestigation of wind induced vibrations of silos using 2D and 3D CFD simulations
Wind induced ovalling vibrations were observed during a storm in October 2002 on several empty silos of a closely spaced group consisting of 8 by 5 thin-walled silos in the port of Antwerp (Belgium). To clarify the cause and location of the observed silo vibrations, a thorough analysis of the aerodynamic pressures on the silo surfaces is required. Therefore, both 2D and 3D computational fluid d...
متن کاملSuppression of the vibrations of wind turbine towers
We investigate the suppression of the vibrations of a wind turbine tower using colocated feedback to achieve strong stability. We decompose the system into one model describing the vibrations in the plane of the turbine axis and another model in the plane of the turbine blades. In the plane of the turbine axis, we obtain a non-uniform Spacecraft Control Laboratory Experiment (SCOLE) model with ...
