The purpose of this study is to analyze the failure of open window glass in a high-rise building by strong wind. Since most high-rise buildings in Korea are residential buildings, there is a possibility that window remains open when strong wind occur. The failure of window glass can not only primarily damage house, but can also cause serious damage due to the flying of window glass debris. In this study, Building wind analysis was conducted by FSI(fluid-structure interaction) analysis the case where the actual open window glass was failed due to strong winds. As a result of the FSI analysis, it was found that wind pressure considering the building wind was greater than the wind pressure of the Korean standard and the subject window glass closing occurs before the failure due to limit deformation. Therefore, it was determined that the target window was damaged due to the impact caused by closing due to strong wind, and the impact load was calculated. Rotational motion equation of window system was used to calculate the impact force. The impact force value obtained in this study is the impact force value generated on the subject window system, not the minimum impact force value when the window glass is failed. If closing loading experiment is conducted on the open window system, the wind pressure that generates window glass failure be obtained. If it is applied to the window system design the values obtained through the experiment, failure of open window glass would be prevented.
