Input
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")
Step
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.
Components
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 stre
Combined(Axial+Moment)
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.
Type of Display
Define the type of display as follows :
Contour : Display the stresses of beam elements in contour.
Deform : Display the deformed shape of the model.
Values : Display the stresses of beam 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 beam 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 location at which internal stresses of the beam elements are produced in numerical values.
I : Display the stress at the start node (N1) of a beam element.
Center : Display the stress at the center of a beam element.
J : Display the stress at the end node (N2) of a beam element.
Max : Display the maximum stress among the stresses at the quarter points of each beam 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 : 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 : Specify the Base Files to perform Batch Output Generation, construction stages, load cases (combinations), steps, etc. in the following dialog box.
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.
Stages
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 non-linear 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 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.
Import /Export is only meaningful for different projects. In a given structural model, the Base Files are automatically stored and listed.
