Load Cases/Combinations

Select a desired load case, load combination or envelope case.

Click ....png to the right to enter new or modify existing load combinations. (Refer to "Load Cases / Combinations")

Specify the step for which the analysis results are to be produced. The Step is defined in geometric nonlinear analysis as Load Step, and additional steps are defined in the construction stages of highrise buildings or heat of hydration analyses.

NOTE.png The Construction Stage applicable for the output of the construction stage analysis is defined in Select Construction Stage for Display or Stage Toolbar./span



Select the desired stress component among the following :

Part : Select a specific part for which member forces will be produced. This function is activated when parts are defined in the Composite Section for Construction Stage

Sax : Axial stress in the element's local x-direction

Ssy : Shear stress in the element's local y-direction

Ssz : Shear stress in the element's local z-direction

Sby : Bending stress in the element local y-direction due to the bending moment about the element's local z-axis

Sbz : Bending stress in the element local z-direction due to the bending moment about the element's local y-axis

Combined : Combined stress (maximum or minimum value among Sax ± Sby ± Sbz)

7th DOF :

Sax(Warping) : Warping Normal Stress

Ssy(Mt) : Shear Stress due to Twisting Moment (τxy)

Ssy(Mw) : Shear Stress due to Warping Moment (τxy)

Ssz(Mt) : Shear Stress due to Twisting Moment (τxz)

NOTE.png Combined stress is calculated as (Sax ± Sby ± Sbz), and if 7 degrees of freedom are considered in the cross-section configuration, the combined stress is calculated as the maximum/minimum value among (Sax ± Sby ± Sbz ± Sax (Warping)).



Maximum : Combined stress representing the absolute largest among combined stresses at 1, 2, 3 and 4

1(-y, +z) : combined stress at 1

2(+y, +z) : combined stress at 2

3(+y, -z) : combined stress at 3

4(-y, -z) : combined stress at 4

Contour Options : Specify options for contour representation

Contour Fill

Gradient Fill : Display color gradient (shading) in the contour.

Draw Contour Line Only
Display only the colored boundaries of the contour.

Mono line : Display the boundaries of the contour in a mono color.

Contour Annotation
Legend or annotation signifying the ranges of the contour is displayed.

Spacing : Display the spacing for the legnd or annotation.

Coarse Contour (faster) (for large plate or solid model)
Represent a simplified contour for a large model using plate or solid elements in order to reduce the time required to represent a complete contour.

Where plate elements or solid elements along a cutting plane are represented in contour, a three dimensional contour is created. The positive direction of the analysis results is oriented in the z-axis direction of the local element coordinate system.
The option is not concurrently applicable with the Deformed Shape option. Similarly, the option cannot be concurrently applied to the cases where the Hidden option is used to display plate element thicknesses or the Both option is used to represent Top & Bottom member forces (stresses).



Display the deformed shape of the model.



Deformation Scale Factor
Magnify or reduce the size of the displacement graphically displayed in the model window.

Deformation Type
Select the type of display for displacement

Nodal Deform : Display the deformed shape only with nodal displacements.

Real Displacement (Auto-Scale off) : The true deformation of the structure is graphically represented without magnifying or reducing it. This option is typically used for geometric nonlinear analysis reflecting large displacement.

Relative Displacement : The deformation of the structure is graphically represented relative to the minimum nodal displacement, which is set to "0"



Display the forces/moments of plate elements in numerical values.

The font and color of the numbers can be controlled in Display Option.



Decimal Points : Assign decimal points for the displayed numbers

Exp. : Express as exponentials

Min & Max : Display the maximum and minimum values

Abs Max : Display the absolute maximum value

Max : Display only the maximum value

Min : Display only the minimum value

Limit Scale(%) : Set the screen display limit for internal forces relative to the selected maximum or minimum value

Set Orientation : Display orientation of numerical values

The default Decimal Points can be controlled in "Preferences".
Set Orientation = 0 horizontally displays the numerical values to the right of nodes or elements.
The orientation angle represents the counter-clockwise direction, which may be used to enhance the readability of the numbers.



Display various references related to analysis results to the right or left of the working window.

Element numbers pertaining to the maximum and minimum forces are displayed.



Legend Position : Position of the legend in the display window

Rank Value Type : Specify a type of values in the Legend and the number of decimal points

Check on only the load (combination) conditions that will be used to produce batch outputs. This column becomes inactive if "Post CS Loads" is selected or no construction stage analysis is carried out.
