Traction liernes

Recommended Posts

Bonjour,

comment calculer les efforts de traction des liernes pour le dimensionnement des pannes. Je comprends pas le N1=R/2 et N2=N1+R et N3=R+N2.

merci!

Merci Mr elmahsani ms j’arrive pas à shématiser l’effort provenant du sablière et la moitié de la charge car la charge appliquée sur la panne est constante donc  T1=1.25hl/2 ( effort de l’appui)
