摘要(Abstract)：

近年来建筑结构的爆炸事件频繁发生,而我国目前还没有统一的建筑结构抗爆设防目标。基于安全性风险评估理论,利用爆炸风险平均发生概率和爆炸风险破坏程度的等级划分,确定爆炸风险的平均影响程度。结合我国《建筑结构可靠度设计统一标准》和实际爆炸事件的特点,提出基于建筑结构重要性的抗爆设防等级分类方法,从而确定抗爆安全等级。根据我国国情综合考虑建筑结构抗爆安全等级和爆炸超压强度等级,确定不同类型建筑结构的抗爆设防指标。建立了以建筑结构设防目标作为工程抗爆设计的基础原则,通过对以往爆炸事件的统计分析,确定不同爆炸超压荷载对人员伤亡和建筑结构损伤程度的设防目标,为建筑结构抗爆设防指标提供一种新的方法。

关键词(KeyWords)： 比例距离;爆炸强度等级;建筑结构爆炸安全等级;抗爆设防指标
