Behaviour of raked column subjected to blast loading

An explosion generates a blast wave that lasts only a few milliseconds and when detonates it produces an increased pressure involves a violent and sudden burst of energy that can cause catastrophic damage within or around the building resulting in a collapse of an external and internal portion of th...

Description
Summary:An explosion generates a blast wave that lasts only a few milliseconds and when detonates it produces an increased pressure involves a violent and sudden burst of energy that can cause catastrophic damage within or around the building resulting in a collapse of an external and internal portion of the building. An analytical study has been carried out to know the behaviour of raked columns under blast loading using Coupled Eulerian–Lagrangian (CEL) method. This study investigates the blast wave interaction of raked columns subjected to blast loading. The behaviour of raked columns under blast loadis studied by varying the standoff distance and amount of explosive. The analytical results show that the charge weight and standoff distance are the key parameters deciding the stability of the structure. Graphical abstract The blast wave developing inside the Eulerian domain from 0.5 to 4.07 ms is shown in Fig. A–F for 50 kg TNT at a standoff distance of 5 m. Figure G–L represent the development of explosion wave in the isosurface at 0.5 ms and blast wave leaving the domain at 4.07 ms.
