Abstract

U posljednjih par desetljeća javlja se sve veća potreba analiziranja udarnog djelovanja eksploziva na konstrukcije od armiranog i mikroarmiranog betona. Pri detonaciji se stvara udarni val kojeg karakterizira nagli porast tlaka do vršnog tlaka, pri kojemu su moguća oštećenja ili popuštanje betonskih konstrukcija. S obzirom na dostupnost potrebnih materijala i jednostavnost izrade eksploziva kućne radinosti, postoji zabrinutost za sigurnost ljudi i pojedinih građevina uslijed terorističkih aktivnosti. Istraživanje djelovanja eksploziva važno je zbog razvoja materijala i zaštitnih elemenata otpornih na detonaciju, ali također i za otkrivanje slabih točaka na strukturama te za sprječavanje progresivnog kolapsa. U radu je dan pregled različitih ispitivanja djelovanja eksploziva na građevine od betona.

Abstract (english)

Over the recent decades, many papers have been published on the behaviour of regular and fiber reinforced concrete under blast loading. Explosive detonations create a blast wave, characterized by an almost instantaneous rise of atmospheric pressure to a peak overpressure, which might damage the building, or even cause structural failure. Considering the availability of required materials and the simplicity of manufacturing certain improvised explosive devices, there is a growing concern for the safety of the general population and for the safety of the infrastructure of a nation amidst terrorist activities. Analysing the effects of blast loading is not only essential for developing new materials and protective elements, but is also crucial for detecting any weak points a structure may have and preventing progressive collapse. This paper presents current studies on the effects of blast loading on concrete structures.
