23-77 CONSIDERAȚII PRIVIND SOLICITAREA DINAMICĂ PRIN ȘOC A MATERIALULUI UZUAL UTILIZAT PENTRU PARAPETELE DE PROTECȚIE LA DRUMURI


CONSIDERATIONS ON DYNAMIC LOADING BY SHOCK OF
MATERIAL USUAL USED ON ROAD RESTRAINT SYSTEMS
This paper presents a presentation between the results of experiments
conducted by dynamic loading by shock of the material which is made the road
restraint systems, S235JR black and galvanized. For an appropriate safe level,
protection systems must absorb as much energy as possible during impact,
maintaining their integrity. Road restraint systems protect the road vehicles
from dangers, which are forwarded to the roadway minimizing serious injury.
Restraint deformed metal systems components are made of S235JR, S275JR
or other equivalent. After road restraint systems components execution, they
are promoted to the technological flow hot dip galvanizing, which are protected
against corrosion.
