Abstract:With the help of the nonlinear finite element code LS-DYNA, a discrete finite element model was developed to numerically simulate the dynamic response of the reinforced concrete containment under internal blast loading by employing a fluid-structure-coupling algorithm. And the simulated results were compared with those by the Henrych formula as well as ones in the TM5-1300 standard, respectively. The comparisons indicate that a reliable simulation can be achieved by the developed model for the reinforced concrete containment subjected to the internal explosion under the scale distance of 3.258 m/kg1/3 when the explosion source is 48 m above the containment base.
