| Abstract |
As a large number of middle, low and high?rise buildings are clustered densely in urban downtowns, various types of damage are caused by the wind occurring around the buildings. Newly constructed apartment complexes are exposed to the risk of strong winds at the corners of apartment buildings or gusts on the pedestrian passages. In Korea and other countries, research is being made on pedestrians’ safety in connection to wind flow inside and outside apartment complexes constructed in downtown areas. This study selected 3 types of apartment complexes, and compared the wind velocity ratio among different spots in the complexes through wind tunnel experiment and CFD analysis. Furthermore, we changed the deployment and outward form of apartment complexes through CFD analysis and examined the wind velocity ratio reduction effect. According to the results of wind tunnel experiment, wind velocity between two buildings decreased usually, but wind velocity increased in the space between the sides of two buildings and the space between front and back apartment buildings. Furthermore, when the results of wind tunnel experiment were compared with the results of CFD analysis, they showed similar tendencies except for wake areas. |
