This work contains a comparative analysis of dynamic strenght for two options for concrete reinforcement: classic using steel reinforcement and using composite materials. CSCM is used as a model for concrete, the behavior of reinforcement is modeled by piecewise linear plasticity. For all types of reinforcement, impact is produced at different heights of dropping the impactor. The contact interaction between concrete and impactor is modeled using the ASSC method. The interaction between concrete and reinforcement is modeled via CBIS method. The test results of steel reinforcement of concrete are being verified.
