建筑玻璃安全防爆距离研究

Research on Safe Extent of Architectural Glazing Subjected to Explosion

玻璃作为一种透明或半透明材料,在极大提高建筑魅力的同时也给建筑的安全带来了一些问题,玻璃碎片常常会给人们造成巨大伤害。结合目前严峻的反恐形势,从防爆角度探讨了玻璃的安全防爆距离问题。在分析了玻璃的动力特性后,结合爆炸空气冲击波的传播性质,研究了玻璃在爆炸荷载下的冲击响应,并提出玻璃安全防爆距离的计算方法。为了便于工程应用,经过比较分析提出了简化的安全距离计算公式,并给出各类玻璃的相关参数,为建筑的防爆设计提供参考。

As a kind of transparent or translucent material, architectural glazing caused some security problems while it dramatically raised the level of attractiveness of building. The glass debris often did great harm to people. Combined with present anti - terrorism situation, the paper discussed the architectural glazing safe extent from the aspect of explosion - proof, introduced a method, which was based on the glass dynamic properties and shock wave propagation, and gave out the safe extent formula and parameters. It was helpful for structure explosion - proof design.
