Bonjour,

 

j'ai calculée une poutre à 3 travée de même inertie (50*100)cm²

portée : 15.22   ;  15.49  et 15.23 m

chargement : G=18.57 KN/m² et Q=2.7 KN/m².

sachant que j'ai que (2/3) de G pour caquot minorée c.à.d G =12.38 KN/m²

et ça ma donne les résultats suivant:

 

 

 

 

                   Moments       Travée 1         Appui B       Travée 2        Appui C       Travée 3

Forfaitaire                          667                436.68         480.35         436.68           668.17

Caquot minorée                  347.49          640.7           45.97           641.08           348.08

 

vous en pensez quoi ?

j’attends vos avis & commentaires

 

cordialement
