Calculation precision for one of the diagram
"branches". The value means how many times the strain
plane is readjusted from the position of section under full compression
to the position of section under full tension.
Default value = 180.
The value influences the accuracy and the
speed of calculation.
See Figure 1 below.
Vertical division
Number
of directions in which the diagram is calculated (number of "branches").
Default value = 72.
See Figure 1 below.
Horizontal division
The
value affecting the accuracy of vertical sections. Because "branches"
of the diagram are not generally planar, the calculation of vertical
sections is based on horizontal sections.
Default value = 100.
See Figure 1 below.
Method
of check
The interaction diagram shows the ultimate
bearing capacity. The following approaches can be applied:
Nu
– assuming Md is constant
Mu
– assuming Nd is constant
NuMu
– assuming eccentricity is constant
Muy
– assuming Mdz is constant
Muz
– assuming Mdy is constant
Default value = Muy.
See Figure 2 below.
