Zusammenfassung:In this paper, we strived to the goal to ensure various special structures against damage factors of high-explosive blast. Together with application of combined blast protection devices, we considered reinforcement of constructive elements and simulated the impact and interaction of detonating projectile with reinforced concrete wall. Various packages of computational mechanics which belong to ANSYS family were applied to numerical simulations, as well as the developed numerical model of reinforced media which can be effective in development of combined blast-protective structures for urban environment. Protection devices based of developed blast-protective structures combine influence of blast-absorbing multiphase media with durability of rigid reinforced base constructions, so the numerical simulation of blast wave reflection and projectile impact are also necessary for their research and development. Our computational results, achieved in this study, have shown that, owing to reinforcement, the considered coating slab retained its integrity, though some cracking and ejection of concrete really occurred.
