520			_aNowadays, irregular plan shaped tall buildings is emerging in urban environments due to the development of innovation in architectural design. The present paper is focused on wind behaviour around the T-plan shape tall buildings both by numerically and experimentally. The numerical study is done using computational fluid dynamics (CFD) and validated experimentally using a subsonic wind tunnel. The building models and wind speed are scaled in the ratio 1:300 and 1:5, respectively. The analysis is done for the wind angles 0°, 45°, 90°, 135°and 180° at a wind speed of 10 m/s, and pressure distribution on various faces of the buildings was observed. In order to check the accuracy of the results between wind tunnel and CFD, error analysis is carried using R2, MAE, RMSE and MAPE. From the results, detailed flow patterns such as streamlines, the formation of a vortex, stagnation point, upstream and downstream flow, wake formation were represented graphically and further drag and lift coefficients were studied in the above-said wind angles. It is observed that minimum drag is obtained at a 90° wind angle. Since the drag value has a direct impact on wind loads on buildings, 90°wind angle is the desired orientation for T-plan shapes tall buildings.
