Why is the unit of point load kN/m in PLAXIS 2D? Are 10 kN/m in PLAXIS 2D and 10 kN in PLAXIS 3D same?
Dear Debasmita,
This is because in PLAXIS 2D we assume that the model is under plane strain conditions. The assumption here is that we have 1m slice of a model and in the out-of-plane direction, therefore the calculated forces resulting from prescribed displacements represent forces per unit length in the out-of-plane direction.
A point load in PLAXIS 2D is actually a line load in PLAXIS 3D.
So, the 10 kN/m of a point load is considered to be a line load of 10 kN with a length of 1m in PLAXIS 3D.
