변장비가 2인 주변건물에 의한 고층건물의 풍하중 상호작용에 관한 연구

The evaluation of wind loads on buildings in Korea is carried out mainly by using Korean Standard Design Loads for Buildings. whose specifications are generally based on wind-tunnel tests performed on isolated structures considering wind exposure. However, it has been shown that wind loads on buildings in realistic environments surrounded by neighboring buildings may be considerably different from those measured on isolated buildings. Wind-induced interference effects depend mainly on the geometry and arrangement of these structures, their orientation and upstream terrain conditions. The most important factor among them is the arrangement of building structures. It is examined in this study that how wind loads on a high-rise building with square section are affected by the arrangement of neighboring buildings with side ratio of 2.0 to the measured building. Wind-induced interference effects on high-rise buildings were performed by wind-tunnel tests of force balance model. Interference factor was defined as ratio of wind force on a building with interfering buildings present to wind force on an isolated building.
