Reduction of wind induced motion utilizing a tuned sloshing damper
AbstractServiceability of buildings is affected by excessive acceleration experienced at the top floors in wind storms that may cause discomfort to the occupants. To ensure functional performance of tall buildings it is important to keep the frequency of objectionable motion levels below the discomfort threshold. This paper addresses a new approach that facilitates mitigation of wind induced motion of buildings utilizing tuned sloshing dampers. First, a theoretical background of the fluid sloshing system is given, which is followed by modeling of sloshing fluid and structural systems. An example of a tall building equipped with a tuned sloshing damper is presented to illustrate the effectiveness of such devices in mitigating structural motion. Finally, a brief discussion of the potential for practical applications is presented.
