    Abstract

    Due to series of military invasions among countries, development of probabilistic models for predicting the effect of various local hard missile impact on reinforced concrete (RC) protective panels gained momentum. Parameters of the study include penetration depth, perforation limit, ballistic limit of missile, and residual velocity of missile. These probabilistic models are developed using the union of experimental tests (Berriaud’s test in 1978) and finite element numerical results. The components are residential slabs, bunkers, containments, aircraft shelters, and storage tanks. Numerical modelling is sculpted in Hypermesh and post-processed in LS-DYNA. These models are grounded on Gardoni’s probabilistic technique in association with the Bayesian approach. The established formulae account for all aleatoric and epistemic uncertainties involved in missile impact interaction with the target, geometrical configurations, material properties, and measurement errors. Also, these models account for strain rate & inertia effect, the multi-modal response of structure, and multiple transitions of failure modes, etc. The prediction from the developed equations has been validated with the experimental results, in order to verify the reliability and credibility of the estimated equations. Not alone missile impact but present study can accommodate wind-borne missiles, pressure pipes, iron rods, etc
