25-73 EVALUAREA TEORETICĂ A PERFORMANȚELOR UNEI BARIERE DE SIGURANȚĂ RUTIERĂ

THEORETICAL PERFORMANCE EVALUATION
OF A TRAFFIC SAFETY BARRIER
By definition, the railing is a wall or a railing of little height which serves
to delimit the edge of a road, a bridge, aimed at stopping vehicles and
restoration mainly on the carriageway, pedestrians and conveyance of other
road users. Protective guardrail road safety ensures good road contact because
a vehicle deforms elastically, annihilating shock.

22-44 COMPORTAREA OŢELULUI PENTRU CONSTRUCŢII LA TEMPERATURI ÎNALTE

The purpose of the present paper is to determine the response of
main elements and resistance structures to extreme circumstances, specifically
to action of conflagration, considering the temperature distribution inside
structure’s elements, materials characteristics – steel for this case – following
the determination of thermo-mechanic response of main elements and
resistance structures.
