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. 0aTall buildings0 aPennung Warnitchai,eChairperson1 aAnwar, Naveed,eExamination Committee0 aNoppadol Phien-Wej,eExamination Committee2 aNetherlands Ministry for Development Cooperation,eScholarship donor  3Full-Textuhttp://203.159.5.9/ait-thesis/detail.php?q=B04774  a.b12341769bmnaitcj  a240423  b0c200108dmea  fjg0  c2679d2679
