2D ANALYSIS STRATEGIC STRUCTURE
|Abstract:||The inherent strength of a bunker makes it an effective blast resistant structure. Strategic structures like bunkers are used for the protection of personnel, equipment and for storage of explosives/ammunition. Explosive blasts exert loads of high intensity and short duration on structures in the vicinity of the blast. Explosives even from small charges when • placed close to a structure would result in very high peak pressures and could lead to damage. In this dissertation work, two dimensional analysis of bunkers subjected to blast loads has been carried out. Non-linear transient dynamic analysis for blast loads has been carried out by the general purpose finite element program which includes the numerically integrated isoparametric elements. In the elasto-plastic analysis, Tresca, Von Mises, Mohr-Coulomb and Drucker-Prager yield criteria have been considered. An above ground bunker, a bunker with soil cover and a semi-buried bunker have been analysed for blast loads as recommended by 1S:4991-1968.|
