Abstract
The present paper aims to clarify the range of detailed modeling of surrounding buildings that affect mean wind pressure acting on low-rise building roofs. The study takes its basis in wind tunnel experiments with wind tunnel models that are developed with digital data focusing on a 410 m by 810 m area in the southern part of Osaka prefecture. Taking advantage of the digital data, the height and footprint are considered for all wind tunnel models. In addition, the roof shape is considered for buildings in the vicinity of the target buildings. The series of wind tunnel experiments was conducted by changing the range of the detailed modeling of surrounding buildings. The results indicate that the surrounding buildings within approximately 420 m to 600 m can affect the mean wind pressure of target low-rise buildings.
