From the main menu, select [Results] tab > [Type : Analysis results] > [Result Display] group > [Stresses] > [Beam Stresses]
Select a desired load case, load combination or envelope case.
Click 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 non-linear analysis as Load Step, and additional steps are defined in the construction stages of bridges or heat of hydration analyses.
The Construction Stage applicable for the output of the construction stage analysis is defined in Select Construction Stage for Display or Stage Toolbar.
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 : Normal stress resulting from the moment (Mz) about the element's local z-axis
Sbz : Normal stress resulting from the moment (My) about the element's local y-axis
Combined : Combined stress (Combined stress: Sax ± Sby ± Sbz). When warping effect is considered in Section Properties, combined moment is obtained by maximum or minimum value of Sax Sby Sbz Sax(Warping).
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)
Ssz(Mw) : Shear Stress due to Warping Moment (τxz)
Combined(Ssy) : Shear Stress due to “Transverse + Twisting Moment + Warping Moment”(τxy)
Combined(Ssz) : Shear Stress due to “Transverse + Twisting Moment + Warping Moment” (τxz)
Combined stress is calculated as (Sax ± Sby ± Sbz), and if the 7-degree-of-freedom option is selected in the section definition, the combined stress is calculated as the maximum/minimum value of (Sax ± Sby ± Sbz ± Sax(Warping)).
Maximum : Combined stress representing the absolute largest among combined stresses at 1, 2, 3 and 4 (the location 1, 2, 3 and 4 shown in the Section Shape of the Section Data window)
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
When applying the Chinese Standard Load CJJ77-98 to the structural design, the distributed load Qm is used to calculate the combined stress based on the sectional forces induced by the load.

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.
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

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.
