Research on safety range of architectural glazing under blast loading

As a kind of transparent or translucent material, architectural glass is widely used in modern buildings, but it is easily broken under explosion shock, resulting in wounding fragments. Combined with present anti-terrorism situation, this paper discussed the safety range of architectural glazing from the point of explosion-proof. And using the theory of elastic vibration and considering the propagation characteristics of blast shock wave, the dynamic responses of the architectural glazing under blast loading were theoretically analyzed and the maximum stress and deflection were obtained. Based on the theory of the strength of glass, a calculation method for the safety range of the architectural glazing was proposed. For application convenient, the simplified formula for the safety extent of architectural glazing under explosion and the parameters of different glass were presented. It was helpful for structure explosion-proof design.
