Bonjour,
problèmes de terminologie entre contrainte de rupture su sol et contrainte admissible du sol dans le module Semelle / SOL/ normes CSA/ACI/BS Geo de RSA, svp lisez les pièces jointes.Une réponse rapide serait appréciée.
Merci
Explanations for Patrick sent some time ago. Now some summary.
1/ mistake in Help topic http://docs.autodesk.com/RSA/2013/ENU/filesROBOT/GUID-8CED5DA6-06CA-4043-ACA5-B982916AE2E8.htm
instead of q_ult/3 ≤ q_SLS it should be q_ult/3 ≥ q_SLS
2/ not explained in Help superposition&interaction of safety factors 3 (from the code) and user defined value of SF for Capacity from Geotechnical Options - such superposition is observed for Calculated/calculee soil stress
Assuming that SF is safety factor defined for Capacity in Geotechnical Options it seems that:
a/ for Allowable/"de rupture" soil stress
SF ≤ qULT/qSLS
b/ for Calculated/calculee soil stress
SF ≤ qULT/3/qSLS
Above effects reported to be fixed.
