Plots the 2D interaction diagram of a prestressed concrete section according to the selected direction.

POST1:Concrete Checking

Entity

Label identifying the entity type to be drawn.

BEAM	Beam element
SOLSEC	Solid section
CUT	Support beam cut
VERTEX	Shell Vertex

NUM

Number of beam element, solid section, cut or shell vertex.

KeyIJ

End to be considered. Ignored for solid sections or shell vertices.

If Lab = ‘BEAM’:

KeyIJ = I           I section.

KeyIJ = J          J section.

If Lab = ‘CUT’:

KeyIJ = I           Left section.

KeyIJ = J          Right section.

DIRKEY

Key identifying the direction to analyze the section.

For solid sections, cross sections and cuts:

DIRKEY	Description
0	Bending in XY plane of element coordinate system (Mz Moments). (Default value).
1	Bending in XZ plane of element coordinate system (My Moments).

For shell vertices

DIRKEY	Description
0	X direction.
1	Y direction.

KEYPL1

Plot point.

KEYPL1	Description
0	Dot included (default value).
1	Dot not included.

KEYPL2

Diagram plot options.

KEYPL2	Description
0	Plot only prestressing section diagram (default value).
1	Add reinforced concrete interaction diagram.

N

Axial force.

M

Moment.

VAL1

Not used.

VAL2

Not used.

VAL3

If the active code is ACI 318-05: Type of member (different strength reduction factors for axial compression, and axial compression with flexure are used in each case).

1	Members with spiral reinforcement (f = 0.70).
0	Other cases (f = 0.65). Default value.

 

If the active code is ACI 349-01: Type of member (different strength reduction factors for axial compression, and axial compression with flexure are used in each case).

1	Members with spiral reinforcement (f = 0.75).
0	Other cases (f = 0.70). Default value.

 

If the active code is ACI 359-04: Load category.

0	Factored loads.
1	Service loads.

VAL4

If the active code is ACI 359-04: Force Classification.

0 or 1	Primary forces.
2	Primary + Secondary forces.
3	Primary forces + SIT
4	Primary + Secondary forces + SIT.
5	Primary forces + SIT (RG 1.90).
6	Primary + Secondary forces + SIT (RG 1.90).

VAL5

If the active code is ACI 359-04: Type of stress-strain diagram used for concrete.

Blank	Diagram selected as the Design Diagram in the material.
             0	User defined.
1	PCA parabolic
2	Rectangular
3	Parabolic ACI359
4	Linear ACI359

 

Notes

- If N and M are defined, they are considered; if not, the forces and moments corresponding to the selected end and active load step are taken.
