Abstract
In this study, the structural performance of nuclear power plant containment buildings, which are made of steel fiber reinforced concrete(SFRC) and subject to aircraft crash, is examined by finite element analyses. The applied loads by aircraft crash against the buildings are modeled using Riera impact load function and by the varying aircraft contact area with respect to time. CSCM concrete model in LS-DYNA is employed to model SFRC. The parameters for the material model are determined from SFRC strength prediction models. Based on the volume ratio of steel fiber in SFRC, the structural performance of nuclear containment buildings subject to aircraft crash are analysed using a commercial finite element analysis program LS-DYNA. The safety assessments of the buildings subject to the crash are discussed and the effectiveness of SFRC for nuclear power plant containment building on the increase of aircraft crash resistance is also evaluated.
