This paper examines the influence of the different factors that affect the problem of the collisions against the concrete safety barriers used to narrower the carriageways. In particular we studied both the influenece of the damage of the vehicles and the shear strength necessary in teh joints between the barriere elements.

Abstract
This paper examines the influence of the different factors that affect the problem of the collisions against the concrete safety barriers used to narrower the carriageways. In particular we studied both the influenece of the damage of the vehicles and the shear strength necessary in teh joints between the barriere elements.
