Aeroelastic behavior of tall buildings in wakes
AbstractExtensive wind tunnel studies of the interaction effect between two similar size structures were reported in previous publications, however only a few researches on the mutual interference between different size structures have been published to date. The increased response and its possible aeroelastic mechanism of a high-rise rectangular building under the interference excitation of several types of upwind buildings with different breadths have been investigated in this paper. In a low turbulence shear layer over open country terrain, the cross wind response of the downstream resonance and increase up to 20 times as large as that of the isolated building at lower reduced velocity ranges of 5∼6. This aerodynamic instability is considered due to the alternate wake deformation, i.e., the switching excitation produced by the interference effect between two buildings. The along wind response has a tendency to increase with the size of upstream building, i.e., with the scale of vortices created by an upstream building.
