Aerodynamic shape effects of tall building for vortex induced vibration

Hayashida, H. / Iwasa, Y.

AbstractThe effects of building plan shape on aerodynamic forces and displacement response have been studied for super high-rise building with an assumed height of 600 m in a wind tunnel. Experiments have been carried out using rigid models with eight kinds of building plan shapes of equal area ( $= 6400 m$ ²), equal building height ( $= 600 m$ ), and equal density ( $= 125 kg/m$ ³). The measurement model force had been combined analytically with a computer model of the building to provide estimates of the actual building response. The dynamic response behavior of a super high-rise building under strong wind due to vortex shedding and the aerodynamic damping effect of vibration by changing the cross section of building were clarified from these results.
