本文提出了一种在无法确定弹坑位置的情况下确定恐怖袭击中爆炸物位置和质量的方法，并将其应用于1994年7月发生在阿根廷布宜诺斯艾利斯的以色列-阿根廷互助协会大楼袭击事件。对同一条街道上一个街区的相对建筑物排所对应的拥挤的城市环境进行了计算动力学分析。模拟了不同位置、不同药量下的多个方案，并对相应的压力和冲量分布进行了评价。借助于等损伤曲线。模拟不同方案的建筑物立面损伤分布，并将其与真实的观察到的损伤模式进行比较。这种方法可以确定爆炸焦点最可能的位置以及攻击中使用的爆炸物的质量。(C)2004 Elsevier Ltd.保留所有权利。
A methodology to determine the location and mass of explosive in a terrorism attack when the location of the crater is unavailable is presented in this paper and applied to the case of the AMIA (Israel-Argentina Mutual Association) building attack that occurred in Buenos Aires, Argentina in July 1994. A computational dynamic analysis was carried out over the congested urban environment that corresponds to the opposite rows of buildings of a block, in the same street. Many alternatives corresponding to different locations and explosive mass were simulated and the corresponding distribution of pressures and impulses which were used to evaluate. with the aid of isodamage curves. the distribution of damage on building facades for the different alternatives simulated and compare them with the real observed damage patterns. The methodology allows the determination of the most probable location of the focus of the explosion as well as the mass of the explosive used in the attack. (C) 2004 Elsevier Ltd.
