bentafat_rachid Posted May 17, 2009 Report Share Posted May 17, 2009 salam il s"agit d'une simple étude comparative d'une structure formée par deux voiles liés par des linteaux . le logiciels Etabs staadpro v8i ; sap2000 donnent des résultats logiques , par contre avec robot , je remarque que la somme des efforts tranchants à la base est largement supérieure à l'effort horizontal qui sollicite la structure au sommet . j'ai remarque que la somme des efforts T1+T2 tend vers la valeur de l'effort extérieur lorsque le maillage est raffiné !! chose qui diminue la performance de ce logiciel . s'il sagit d'une etude d'un grand projet , la convergence exige donc une Ram de 10 gega . hauteur des trumeaux 9m largeur des trumeaux 4m e=30 cm Coffrage des poutres linteaux 30 x50 cm . Longueur poutre linteau = 2 m la force nadale statique = 100 kn . voici le modéle ROBOBAT . la somme des efforts réduits "Efforts tranchant " dépasse la charge extérieure !!! T1 = 81.08 kn coupe A-A1 T2 = 106.59 KN coupe A-A2 logiquement T1+T2 doit etre egale à 100 KN NB ; CETTE ANOMALIECONCERNE UNIQUEMENT LA MÉTHODE COUPE SECTION.mais la méthode réaction d'appuis donne des résultats logiques Quote Link to comment Share on other sites More sharing options...
