Research on Assessment Method of Ammunition Damaging Typical Reinforced Concrete Building

Abstract

To calculate the efficiency of ammunition damaging reinforced concrete buildings, the damage assessment method of reinforced concrete buildings under the ammunition strike was established based on engineering calculation models. The calculation method of building component's damage under explosive load was proposed based on the equivalent single degree of freedom model. The relationship between the damage of component and the damage of building was established, and the calculation model of the degree of building damage at the designated ammunition attack position was obtained. Combining the scattering law of the ammunition, the calculation method of the damage of building considering the hit error of the ammunition was established. A model of ammunition and a reinforced concrete building was constructed, and the effectiveness of the constructed ammunition damaging the constructed building was calculated based on the proposed method. The influence of ammunition's elevation angles, azimuth angle and speeds on damage efficiency was analyzed. The proposed method is feasible and efficient, and it can provide technical support for attacking plans.
