APPLICATIONS OF A COUPLED MULTI-SOLVER APPROACH INEVALUATING DAMAGE OF REINFORCED CONCRETE WALLS FROMSHOCK AND IMPACT

摘要

Sabotage from terrorist actions threatens the safety of nuclear power plants and materials. Physical barriers,usually made of steel reinforced concrete must be constructed around areas to be protected and must have adequatestructural strength to prevent failure from terrorist threats. Two hypothetical terrorist threats are considered in thepresent paper: blast from the detonation of a truck bomb and impact from a Boeing 747 passenger jet. To simulatedamage and failure of a thick steel reinforced concrete wall under such blast and impact loadings, a CoupledMulti-Solver approach based upon finite element and finite volume methods is applied. The three-dimensionalnumerical simulations are performed with the nonlinear dynamic analysis computer program AUTODYN?. Thedamage developed in the reinforced concrete walls from these threats is investigated and the most successful use ofphysical barriers is discussed.
