Blast Resistance of POZD-Coated Reinforced Concrete Beams under Contact Explosion

In order to obtain the anti-blast performance of polyisocyanate-oxazodone (POZD) coated reinforced concrete beams under contact explosion, numerical simulation studies were carried out on reinforced concrete beams of the same size. Hypemesh and LS-DYNA were used to establish the model of POZD-coated reinforced concrete beams, and the failure modes and damage effects of POZD-coated reinforced concrete beams under contact explosion were analyzed. The failure mode of ordinary reinforced concrete beams under contact explosion was simulated and verified, the failure modes and damage conditions of reinforced concrete beams under different POZD coating positions and different charge amounts were studied, and the protective effects of different POZD coating positions were evaluated.
