Blast Loads and Their Effects on Structures

Abstract

AbstractThe main objective is to investigate the present proceedings on the blast loads on the civil structures as an act of terrorism, industrialization or mining actions. Explosives are detonating materials that explode with high pressure on ignition. The blast explosion inside or at a proximity distance of a structure damages the structure physically, incurring trauma/death to the inmates or people in the surrounding. During the present Anthropogenic epoch, the act of terrorism has surged targeting mainly the commercial units, high-rise buildings, 5-star hotels and crowded places. The bombing action is done through a small packet bomb to suicidal trucks or even aeroplanes. Customarily while designing the imposed loads on a structure, the structural engineers consider the dead, live, lateral and seismic loads but do not consider the blast load. In designing important and high rising structures, it has become pertinent to consider blast loads (dynamic loads) along with other loads. Since it was not warranted, there was no code provision for the blast load in the design of structures. The present research is an attempt to review all the old literature available and to find the research gap before proceeding with the calculation of blast loads in the design of a structure. The conclusions derived from the research gap shall be helpful to understand the behaviour of blast loads on structures and can be useful in designing the important structures.KeywordsBlast loadImpact loadDynamic loadsCollapse analysis
