Internal Forces 2D Results

List of results

There are the following list of results based on selection of Type of values.

• Design (centroid) - forces which are used for design of reinforcement calculated to centre of gravity of cross-section and related to direction (1,2) and surface(+-); these forces are comparable with 1D solution in fact. The forces for upper and lower surface are the same in case of directions(1,2) of designed reinforcement are the same. These forces are calculated based on design (surface) forces and virtual forces

mEd1,+	Dimensional bending moment at centroid recalculated to first defined direction (1) for upper (+) surface
mEd2,+	Dimensional bending moment at centroid recalculated to second defined direction (2) for upper (+) surface
mEd,c+	Dimensional bending moment at centroid recalculated to compression strut in upper (+) surface
nEd,1+	Dimensional normal force at centroid recalculated to first direction (1) and upper (+) surface
nEd,2+	Dimensional normal force at centroid recalculated to second direction (2) and upper (+) surface
nEd,c+	Dimensional normal force at centroid recalculated to compression strut in upper surface(+)
mEd1,-	Dimensional bending moment at centroid recalculated to first defined direction (1) for lower (-) surface
mEd2,-	Dimensional bending moment at centroid recalculated to second defined direction (2) for lower (-) surface
mEd,c-	Dimensional bending moment at centroid recalculated to compression strut in lower (-) surface
nEd,1-	Dimensional normal force at centroid recalculated to first direction (1) and lower (-) surface

nEd,c-	Dimensional normal force at centroid recalculated to compression strut in lower surface(-)
vEd	Shear force resultant

• Basic (centroid) - forces related to centre of gravity calculated purely on FEM (the same forces as are presented in Results >2D members > 2D internal forces

• Principal (surface) - basic forces from surface recalculated to Principal forces in surfaces
