CHAPITRE - A 1 -

PRINCIPES ET DEFINITIONS

ARTICLE - A 1 - DOMAINE D 1APPLIC ATION

Les présentes régles de calculs sont applicables à tous lesouvrages et constructions en béton armé, soumis à des ambiances

s'écartant peu des seules influences climatiques, et dont le bétonest constitué de granulats naturels normaux, avec un dosage en

ciment au moins égal à 300 kg par m3 de béton mis en oeuvre. -

Sont considérées en béton armé les pièces qui sont encoreaptes à jouer leur rôle dans la structure dont elles font partie,lorsque la résistance à la traction par fléxion de leur bétonconstitutif est supposée nulle.

Restent en dehors du domaine des présentes régles :- les constructions en béton non armé,- les constructions en béton constitué de granulats légers,- les constructions en béton caverneux ou cellulaire mixtes acier-

béton,- les éléments soumis en service à des températures s'écartant

sensiblement de celles qui résultent des seules influencesclimatiques.

D'autre part certains ouvrages peuvent faire l'objet de régles particulières auxquelles il est alors fait référence.
