A huge number of structures being built nowadays are wind sensitive due to their slenderness, size, lightweight, and flexibility which is responsible for the continuous vertical growth of major cities. Construction of a tall structure depends upon some major criteria such as withstand lateral pressures brought on by wind, considering the requirements for strength, drift, and the comfort of the occupants. Around the world, tall buildings closely spaced are frequently used. Therefore, the wind load on nearby tall buildings is quite different from the wind load on an isolated tall building. This study carried out a detailed investigation on hexagonal-shaped tall buildings under interference conditions with wind incidence angles (WIA) varying from 0° to 90° at an interval of 15° and from 90° to 330° at an interval of 30°. The distance between the interfering building and the principal building has been taken as 200 mm. A scale of 1:300 is used to study the building model. The numerical analysis is performed using CFD based on the RANS k-ε models to investigate the variation of mean pressure at all the faces of the principal building and compared against the varying WIA for isolated case and interfering case. Interference factors (IF) have been introduced to show how different scenarios are connected. The effects of other buildings on the hexagonal tall building are investigated. For both isolated and interfering cases, a significant fluctuation in the pressure and force coefficient is observed. In both the isolated and interfering conditions, a graphical comparison of the force coefficients for different WIA is also presented. For wind angles of 15°, 45°, and 75°, asymmetrical vortices developed at the leeward side of the buildings. The critical values of along-wind and across-wind force coefficients for an isolated building are 0.75 and −0.64, respectively. Interference Factor (IF) is found to be minimum at an angle of 90° in each of the faces.
