Truss Stresses


  • Check axial stresses in Truss, Tension-only, Cable, Hook, Compression-only and Gap Elements in contours.



From the main menu, select [Poshover] tab > [Diagram] group > [Stresses] > [Truss Stresses]

Truss Stresses dialog box

Load Cases/Combinations

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 nonlinear analysis as Load Step, and additional steps are defined in the construction stages of bridges or heat of hydration analyses.


Select the desired stresses.

All : Display axial stresses for all the truss elements in contour

Tens. : Display stresses for only the members with tension forces in contour

Comp. : Display stresses for only the members with compression forces in contour.

Type of Display

Define the type of display as follows :

Contour : Display the stresses of truss elements in contour.

Deform : Display the deformed shape of the model.

Values : Display the stresses of truss elements in numerical values.

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

Animate : Dynamically simulate the stresses of the truss elements.

Undeformed : Overlap the undeformed and deformed shapes of the model.

Mirrored : "Mirrored" allows the user to expand the analysis results obtained from a half or quarter model into the results for the full model by reflecting planes.

Output Section Location

Assign the section locations at which stresses of the truss elements are produced in numerical values.

I : Display the stress at the start node (N1) of a truss element.

J : Display the stress at the end node (N2) of a truss element.

Max : Display the maximum stress among the stresses at the quarter points of each truss element, at the center of each element.

All : Display i, j & Max simultaneously.

(Batch Output Generation)

Given the types of analysis results for Graphic outputs, generate consecutively graphic outputs for selected load cases and combinations. A total number of files equal to the products of the numbers of checked items in the three columns of the dialog box below are created.

Batch_Output_Generation___.png : Batch Output Generation : Assign a Base File Name under which the types of results (selection data in the Batch Output Generation dialog box for graphic outputs) are stored.

Batch_Output_Generation___.png : Batch Output Generation : Specify the Base Files to perform Batch Output Generation, construction stages, load cases (combinations), steps, etc. in the following dialog box.

Pushover-pushover results-stress-truss stresses-batch.png

Saved Menu-Bar Info's : Listed here are the Base Files. Select the Base File Names for Batch Output.

Delete the selected : Delete all the Base Files selected with the mouse.

When the construction stage analysis is carried out, all the construction stages are listed. We simply select the stages of interests to be included in the batch output. If no construction stage analysis is performed, the column in the dialog box becomes inactive and lists load (combination) conditions.


The results output of all the construction stages are produced. The construction stages are listed below.

Post CS Loads

The results output for only the Final Stage are produced. The construction stages are listed below. If no construction stage analysis is performed, the load (combination) conditions are listed.

Use Saved

Apply only the (saved) step or load (combination) condition selected at the time of creating each Base File.

Stage LCase/LComb

When the construction stage analysis is carried out, the auto-generated construction stage load conditions and the additionally entered construction stage load combinations are listed. 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.

Step Option

Specify the steps for which the outputs will be produced when the construction stage analysis or large displacement geometric nonlinear analysis is performed.

Saved Step : Use only the steps used for creating the Base Files

All Steps : Use all the steps

Output Options

Output File Type

Select a Graphic File type, either BMP or EMF.

Auto Description : At the top left of the Graphic Outputs produced in batch, auto-generate and include the notes such as the types and components of the analysis results, construction stages and steps, load (combination) conditions, etc. The font size, color, type, etc. can be changed upon clicking the ....png button.

Output Path

Specify the path for saving the graphic files to be produced in batch.

File Prefix : Specify the prefix of the Graphic Files to be created. The filenames will be consisted of "Prefix"_"Base File Name"_"Load Comb.".bmp (emf) or "Prefix"_"Base File Name"_"Stage"_"Stage LCase"_"Step".bmp (emf).

Make Output : Produce the specified batch Graphic Files reflecting the contents of the dialog box.

Export / Import

Produce the contents of data input in the Base Files and Batch Output Generation dialog box in a binary type file (fn.bog). Click the Import button and select a fn.bog to use the same output format.

NOTE.png Import /Export is only meaningful for different projects. In a given structural model, the Base Files are automatically stored and listed.
