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

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.
