Abstract

In order to assess the damage of reinforced concrete slabs under the effect of explosion shock wave, finite element models were built with LS-DYNA. Different models under four working conditions in TNT equivalence, reinforcement and slab thickness were considered. Equivalent plastic strain was brought up to indicate the damage of slabs and a damage assessment method was proposed based on principal component analysis (PCA) theory. The assessment result of the new method is consistent with that assessing according to the deflection in deformation direction, which illustrates that the multivariate statistical analysis method can be used to evaluate the damage of reinforced concrete slabs under the effect of explosion shock wave. The method is feasible and will be further applied to other damage assessment.
