The article discusses probabilistic methods for calculating road safety barriers based on the theory of limit states of structures.In this case, the design schemes are presented in the form of a multi-span continuous beam and frame.The frame design scheme is considered in various variants: rigid connection of the profile sheet with posts with rigid supports, hinged connections of the profile flooring with protected posts, rigid connection with posts with hinged supports. All tasks brought to the determination of the limit state. Fencing structures are mainly designed for roadsides, but they can also be used as dividing lanes. A dynamic calculation of a rack with a profile sheet is performed, and the design scheme is defined as a chain with two freedom ties.
