Abstract
Since 1990s many skyscrapers have been built in Seoul. However, gusty winds occur amongtall buildings by descending turbulences due to the upper air blocking. This study aims toinvestigate the wind characteristics of skyscraper prevailing wind direction. In order to evaluatethe building wind in this area, The wind speed and the wind direction were measured usingpropeller type RM-Young wind monitor in this study. The maximum wind speed was recordedby 15.1 m/sec and the main wind direction is WNW and NW. The ultimate purpose of thisstudy is to figure out the phenomena of building wind impact and also to provide essentialbasic data for establishing proper guidelines in building wind impact assessment for skyscrapers in Korea.
