Influence of Interfered Square Buildings on Wind Responses of U-Shaped Tall Building
The computational fluid dynamics (CFD) simulation has been adopted in the present study to measure the wind responses of the U-shaped tall building under isolate and interference conditions for 0° to 360° wind flow at an interval of 15°. The flow streamlines pattern, force coefficient and mean pressure coefficient have been evaluated for each case which demonstrates the variation in building responses in different conditions. The interference factor (IF) is calculated to understand the impact of wind interference on the object building due to the four similar square buildings in parallelogram arrangement around the U-shaped building. The validation and the mesh refinement study are also executed to validate the numerical analysis results. The interfered buildings obstructed the wind flow, which caused a chaotic flow pattern. With the change in the wind flow direction, the significant variation in force coefficient and the tremendous pressure fluctuations on the object building faces have been observed. Due to interference, the massive increase of drag force around 559.94% has been noted in 75° and 285° and an increase of 561.72% in lift force is noted in 15° and 345°. The decrement in drag force and lift force of 140.81% and 84.09% is measured in 90° and 270° flow. At face A and E maximum decrement of 171.46% in mean pressure coefficient is observed at 15° and 345°, respectively. Those similar faces experience a maximum increase of 44.53% at 300° and 60°, respectively. Those critical fluctuations illustrate the requirements of interference study in wind resistance design.
