高层建筑玻璃幕墙的抗爆炸设计

玻璃幕墙是一种融建筑艺术和建筑功能于一体的建筑外维护构件,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。

Blast protection design of glass curtain wall in high-rise building

Glass curtain wall integrating architectural art and function is chosen comprehensively for high-rise building as perimeter elements.At present,high-rise buildings are attacked frequently in terrorist activities around the world,which prompts the architects to take bomb blast resistant into consideration in building construction.In this paper,aiming at bomb blast protection issue of architectural curtain wall,several methods for design in glass curtain wall and calculation rules of blast loads are proposed on the basis of analyzing the building damage principles caused by blast.The schemes of blast trial for glass curtain wall design are presented and the specifications of carrying out the range test are introduced in the end.
