摘　　要：世界各地恐怖主义爆炸袭击和各种爆炸事件呈上升趋势,爆炸给人类及建筑物造成极大的伤害和破坏。据统计,爆炸中大多数人员伤亡是由建筑玻璃破碎的碎片造成的。目前已对建筑夹层玻璃在冲击等荷载下的破坏强度、动力响应、安全性及经济性等方面进行了某些研究,有关其在爆炸冲击荷载下的性能研究还处于初步阶段,试验和有限元数值模拟成为其主要研究手段。对抗爆玻璃性能、研究分析方法及冲击荷载作用下建筑夹层玻璃的破坏研究现状做了较全面的综述。Terrorist bomb attacks and various bomb events are on the rise all over the world. High-explosive detonations cause extensive damage to both the human beings and the buildings. It is estimated that the majority of nonfatal injuries from bomb blasts result from flying fragments from architectural glazing. At present failure strengths, dynamic response, safety and economy of architectural laminated glazing are investigated, and performance research under explosive load is still in its initial stage. Blast-resistant experiment and finite element simulation of glazing are the main research means. This paper presents a review of blast-resistant glazing properties, research and analysis methods and recent studies on the failure of laminated glazing under bomb blasts.
