A feasible approach to avoid falling objects is to set up a protective plate on the ground floor of the building. And the width of has attracted considerable concerns. Although people have worked out some basic rules for the width of a protective plate of multiple-layer or high-rise buildings for present construction, but those rules lack theoretical research, and there are still some shortage of clear and definite regulations for a super high-rise building. For construction reference, this article is going to find the relation between the spreading range and height of falling objects, and figure out the construction data table and simplified calculating formula of the width of the protective plate by way of theoretical analysis while considering the influence of air 下载后可任意编辑resistance.KEYWORDS: Falling objects, Spreading range, the width of the protective plate, Air resistance, Construction1 绪论随着中国改革开放的深化, 多层建筑已不能满足国家进展的需要...
