Abstract

In typhoon weather, the wind-born debris caused by the rupture of the glass curtain wall is the main reason for the large-scale damage to the glass curtain wall. This paper mainly discusses the accurate mathematical model of glass curtain wall damage rate under the probability of a typhoon attack, as well as the potential and expected value of losses caused by the typhoon of a skyscraper in Hong Kong. Results show that the output of the mathematical model is roughly normally distributed around the actual values which can approximately reflect the potential loss of a skyscraper in a strong typhoon. Discussion of the correlation of wind speed and height, the influence of the surrounding low-rise buildings, and the material of glass enhance the applicability of the results. Meanwhile, it is difficult to fully consider the complexity of the surrounding environment, which is the limitation of this study. However, this study can still benefit urban planning, architectural engineering, and insurance companies.
