Pile axial capacity (pile cap:EC2)
Annex A of EC7 allows bearing capacity to be checked using two sets of partial factors: A1 and A2.
In Tekla Structural Designer the bearing capacity check is performed on STR load combinations using set A1 and on GEO load combinations using set A2.
Pile capacity passes if:
Rc,d ≥ Pn ≥ - R t,d
where
Rc,d = Pile design compression resistance
Rt,d = Pile design tension resistance
Pn = Pile load
