This paper proposes a new analysis of previous works related to the concrete tensile behaviour under impact loadings.

This analysis permits to conclude that:
1. Inertial effects do not exist in concrete specimen under impact loadings until tensile stress rates of 100 GPa.s-1.
2. Viscous phenomena lead to the existence of a unique relation, relevant for all concretes, linking the evolution of the tensile strength in function of the logarithm of the tensile stress rate until tensile stress rates of 100 GPa.s-1.

The paper also proposes strategies of modeling the behaviour of concrete constructions under impact loadings.?

Keywords: Concrete; Strain rate effect; Tensile behaviour; Numerical models.
