高层建筑玻璃幕墙冲击波防护问题的研究

玻璃幕墙是一种融建筑艺术和建筑功能为一体的建筑外围护构件,在高层建筑中得到广泛应用。近年来,世界各地袭击高层建筑的恐怖活动频繁发生,促使建筑设计中逐渐考虑到建筑的抗爆炸设计要求。文章针对建筑玻璃幕墙的爆炸冲击波防护问题,在分析冲击波对建筑幕墙破坏原理的基础上,给出了玻璃幕墙抵抗爆炸冲击波设计的途径,建立了冲击波荷载的计算准则。最后,提出了玻璃幕墙的冲击波试验方案,并具体介绍了距离试验的实施方法。

Research on Blast Protection Issues of Glazing Curtain Wall in High-level Buildings

As one kind of envelope,glazing curtain wall integrated with architecture art and function has been widely used in high-level buildings.At present, high-level buildings are frequently attacked in terrorist activities around the world,which had stirred the architects to take bomb blast resistant into consideration.In this paper,aiming at bomb blast protection issues of glazing curtain wall,several methods for its design approaches and calculation rules of blast load were proposed on the basis of analyzing the building damage principles caused by blast.In addition,the schemes of blast trial for glazing curtain wall design were presented and the specifications of carrying out the range test were introduced.
