| 520 | _a The interference effects from one and many neighboring buildings that do not have identical shapes on tall buildings with complex configuration and vibration mode shapes are studied by a series of wind tunnel tests and numerical analysis. Moreover, to have a more practical view, two real building cases will be investigated in this study to understand about aerodynamic interference effects of surrounding buildings on the principle buildings having complex geometry and vibration characteristics (3D coupled modes). The results show that the 3D coupling analysis slightly influences responses of the first building having lowcoupled effects, but it significantly affects responses of the second building having highcoupled effects. The interfering effects on the buildings{u2019} responses such as displacements and accelerations are investigated by computing interference factors (IF). The shielding, channeling effects and vortex-shedding phenomenon also occur due to the presence of interfering building(s). The shielding and vortex-shedding phenomena have stronger effects on responses of the first building. Namely, while shielding effects reduce the maximum lateral displacements about 2.0 times, highly turbulent wind forces induced by vortex-shedding phenomenon from upstream building increase the maximum acceleration about 3.26 times. | ||
