Huda05 Posted March 26, 2018 Report Share Posted March 26, 2018 (edited) Bonjour, Si je compte renforcer un profilé en IPE travaillant comme étant un poteau disant que je veux "rigidifier" ce profilé pour qu'il atteint les mêmes caractéristiques mécaniques qu'un autre plus performant (exp: IPE400==>IPE450). Selon l'EC3, l'axe de forte inertie est celui parallèle aux semelles du profilé (y-y) et l'axe de faible inertie est celui passant par l'âme (z-z) ! Pardon ! Dans ce cas, la procédure se fait par : - Renforcement de l'âme (ajout de plaque par exemple); ou - Renforcement des ailes du profilé ? En fait, l’ambiguïté réside dans la notion de forte et faible inertie et comment s'en exploiter ... Merci.
