美国规范中门窗玻璃抗爆设计方法探讨

近年来爆炸事故发生的时候,建筑物中的门窗玻璃往往首先发生破坏,破碎的玻璃碎片给建筑物内外的居民及行人造成的伤害往往是巨大的。门窗设计中考虑采用抗爆玻璃是减小玻璃破碎引起人员伤亡数量的有效措施。本文在门窗玻璃抗爆设计概念的基础上,针对美国规范中的两种抗爆设计方法,对门窗玻璃中的建筑玻璃板的设计及门窗连接件的设计方法进行了对比分析,可为国内的门窗玻璃抗爆设计提供参考。

High-explosive detonations first cause extensive damage to glass doors and windows of buildings. The injuries caused by broken shards of glass to the building residents and pedestrians are often huge. In the design of doors and windows the using of blast-resistant glazing is an effective measure to mitigate the casuahies caused by glass fragments. Based on the idea of blast- resistant design of doors and windows, the comparative analysis of two design methods mentioned in American standards on glass plate and framing members and their connecting hardware is carried out. The analysis resuhs could be regarded as a reference for the blast-resistant design of domestic glass doors and windows.
