Casualty analysis of major terrorist attacks in recent decades shows an enormous increase in fatalities and economic losses. Due to frequent terrorist attacks and failure of engineering structures under blast load, this issue has gained the attention of scientists and structural engineers. Recently, threat due to explosions is considerably raised owing to the availability of small size explosive devices with powerful and high range explosive materials. Thus, there is an immediate need for the structures, vulnerable to such tragic events, to be analysed and designed to resist these extreme loading conditions. To predict the behavior of structure under explosion loads, blast load analysis needs to be done. The effective blast parameters such as standoff distance, angle of incidence, explosive type and charge weight with its damaging effects discussed by various researchers have been overviewed in the present work. Further, it is uneconomical to harden the structure to resist the blast load. Therefore, certain strategies which can be adapted to mitigate the effect of blast pressure have also been analysed, and discussed different analytical models for prediction of blast loads. The paper present basics of blast for beginner researchers and structural engineers to understand such complex loading scenario.

爆炸波参数和爆炸载荷减轻方法的批判性回顾

近几十年来对重大恐怖袭击的伤亡分析表明,死亡人数和经济损失急剧增加。由于频繁的恐怖袭击和爆炸载荷下的工程结构故障,这个问​​题已引起科学家和结构工程师的关注。近来,由于可提供具有强力和高射程爆炸材料的小型爆炸装置,大大提高了爆炸的威胁。因此,迫切需要对易受此类悲剧事件影响的结构进行分析和设计,以抵抗这些极端的载荷条件。为了预测结构在爆炸载荷下的行为,需要进行爆炸载荷分析。有效的爆炸参数,例如,对峙距离,入射角,炸药的类型和装药重量及其破坏作用已被许多研究人员讨论,目前的工作已得到概述。此外,硬化结构以抵抗爆炸载荷是不经济的。因此,还分析了某些可以减轻爆炸压力影响的策略,并讨论了预测爆炸载荷的不同分析模型。本文为初学者和结构工程师提供了爆炸的基础知识,以了解这种复杂的载荷情况。并讨论了用于预测爆炸载荷的不同分析模型。本文为初学者和结构工程师提供了爆炸的基础知识,以了解这种复杂的载荷情况。并讨论了用于预测爆炸载荷的不同分析模型。本文为初学者和结构工程师提供了爆炸的基础知识,以了解这种复杂的载荷情况。
