Estimation Method for Wind Load of Building Using Spatial Information

Abstract

Recently, the extent of damage due to localized heavy winds and typhoons has increased because of climate change. Being a peninsula, South Korea is affected by weather patterns arising from the mainland and the ocean as well as dangerous weather phenomena such as hurricanes that occur every year, posing a great danger to the safety of buildings. This study attempts to solve this problem by developing a wind load measurement reflecting method, KBC 2016 criteria. This study employs spatial information to calculate the wind load. By using a reflecting design, the factors affecting the wind load, such as the height of the building, are used to obtain a wind load value. The wind load value applied to a building was calculated, compared, and analyzed with actual application cases. Thus, this study is expected to solve challenges arising when designers calculate the wind load in a subjective and non-scientific manner and will enable the design of more rational and cost-effective wind-resistant buildings.
