Strength analysis of nuclear power plant structures in case of aircraft crash impact

In this article the results of the strength analysis of nuclear power plant structures in case of aircraft crash impact problem are presented.Finite element analysis was performed using ABAQUS CAE system. Nonlinear material models were used, such as “Concrete damaged plasticity” and “Drucker-Prager” for concrete and elastic-plastic model for steel.For the purpose of verification of the mathematical models and engineering methods used in reinforcement concrete buildings strength analysis under different loads (static and transient temperature, structural and other loads), the following computational simulations were carried out: uniaxial compression of the cylindrical concrete specimens; reinforced concrete beams analysis under the static loads;reinforced concrete slab analysis under dynamic loads; reinforced concrete slab analysis under the missile impact. Experimental data for the aforenamed verificatory tasks was found in periodicals.
