Function
- Evaluate the displacements of a model by Displacement Contours
Call
From the main menu, select [Poshover] tab > [Diagram] group > [Deformations] > [Displacement Contour]
Input
Displacement Contour 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")
Step : 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.
Displacement : Display the displacement of the model in contour.
Velocity : Display the velocity in contour.
Acceleration : Display the acceleration in contour.
Absolute Acceleration : Display the absolute acceleration in contour.
Difference between '(Relative) Acceleration' and 'Absolute Acceleration'
Acceleration (Relative) = Acceleration (Absolute) + Observer's Acceleration
As seen from the above expression, Relative and Absolute accelerations differ depending on the presence of Observer's acceleration.
Above items become activated only when time history analysis has been performed
Components
Select the desired displacement component among the following.
DX : Displacement component in GCS X-direction
DY : Displacement component in GCS Y-direction
DZ : Displacement component in GCS Z-direction
RX : Rotation component about GCS X-axis
RY : Rotation component about GCS Y-axis
RZ : Rotation component about GCS Z-axis
Rw : Warping component
DXY =
DYZ =
DXZ =
DXYZ =
Type of Display
Define the type of display as follows.
Contour : Display the displacement of the model in contour.
Deform : Display the deformed shape of the model.
Values : Display the nodal displacements in numerical values.
Legend : Display various references related to analysis results to the right or left of the working window.
Animate : Dynamically simulate the transition process.
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.
Plate Cutting Diagram : Displacement of plate elements is produced in a graph along a specific line or plane cut through the elements. The following dialog box is used to specify the conditions required to generate the displacement diagram along the cutting line/plane.
Current Step Disp. : Produce the displacements pertaining to the selected step of the construction stage if a construction stage analysis has been performed.
Stage/Step Real Disp. : Display the Real Displacements for each construction stage when the construction stage analysis is performed.
(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.
: 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.
: 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
Outputs only the results of the Post CS model. The list at the bottom lists the load (combination) conditions applied to the Post CS model.
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 "Final Stage 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 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.
