NUMERICAL STUDY OF OPTIMIZATION OF INTERFERENCE EFFECT ON PENTAGONAL PLAN SHAPED TALL BUILDING

Tall building designs are changing with the emerging demand of various architectural features and efficient design based on structural geometry. With the growing demand, tall building structures are paving way towards challenging aspects of design with unconventional expressions. More slender structures are proposed with economic and structurally efficient design. This necessitates the study of wind loading effect on various geometrical shapes and also the interference behaviour due to surrounding buildings and their spacing in the neighbourhood. Sufficient availability of pressure and force coefficients for symmetric and regular buildings are provided in various international codes, but they lack the study of interference effect and unsymmetrical building plans. The present research work is a numerical study of wind interference effect and its optimization caused by the change of inter-spacing of interfering buildings and also the varying wind angle of attack on a pentagonal plan shaped building which serves as principle building.
