Abstract

L'invention (schématisée en figure 3b) est destinée à la réalisation d'ouvrages en béton armé (poteaux, poutres, voiles, planchers et toitures d'inclinaisons diverses) particulièrement dans les zones à risques accidentels (séismes ou déflagration). Elle caractérise un ouvrage 1 qui comprend un volume intérieur 4 dont le coffrage est assuré par un dispositif filtrant qui réduit la pression hydrostatique de remplissage, et abouti à une surface de rugosité importante. Ledit volume intérieur 4, qui est ceinturé par une couronne en matière résistante à module d'élasticité élevée (béton armé en général), est rempli par un matériau 5 à 9 compressible ou non mais de viscosité élevée. Sous contraintes accidentelles, dans la zone élastique la ceinture externe 1 qui se déforme réduit le volume intérieur 4. Lorsqu'il est incompressible, l'excédent du produit de remplissage 5 à 9 migre vers un vase d'expansion {7} à travers un orifice de faible section 10. Ces deux propriétés (frottement et perte de charges) sont exploitées afin d'absorber une partie de l'énergie provoquée par les risques accidentels.The invention (shown diagrammatically in FIG. 3b) is intended for the production of reinforced concrete structures (columns, beams, walls, floors and roofs of various inclinations), particularly in areas at risk of accident (earthquakes or explosion). It characterizes a structure 1 which comprises an internal volume 4, the formwork of which is provided by a filtering device which reduces the hydrostatic filling pressure, and results in a surface of significant roughness. Said internal volume 4, which is surrounded by a ring made of resistant material with a high modulus of elasticity (reinforced concrete in general), is filled with a material 5 to 9 which may or may not be compressible but of high viscosity. Under accidental stresses, in the elastic zone the external belt 1 which deforms reduces the internal volume 4. When it is incompressible, the excess of the filling product 5 to 9 migrates towards an expansion vessel {7} through a orifice of small section 10. These two properties (friction and pressure drop) are exploited in order to absorb part of the energy caused by accidental risks.
