Function
- Check the distribution of member forces per unit length in plate elements in Contours or Vectors for each Pushover Step, based on the pushover analysis results.
Call
From the main menu, select [Poshover] tab > [Diagram] group > [Forces] > [Plate Forces/Moments]
Input
Plate Forces/Moments 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.
The Construction Stage applicable for the output of the construction stage analysis is defined in Select Construction Stage for Display or Stage Toolbar.
When pushover analysis is performed for a structure containing Plate, Plane Stress or Solid elements, the pushover analysis results for Plate, Plane Stress or Solid elements can be produced by "Steps"
Plate Force Options
Local : Produce the contour representing member forces per unit width in the plate element local coordinate system.
UCS : Produce the contour representing member forces per unit width in the User-defined Coordinate System for the plate elements placed parallel to the x-y plane in UCS. If UCS has not been defined GCS is applied.
Print UCS Axis : The UCS Axis and View Point activated in the Display settings are visible only on the screen and not displayed in printouts. To enable the option for printing the UCS Axis, activate the option to include UCS Axis in printouts.
Element : Display the contour using the internal forces calculated at each node of an element.
Avg. Nodal : By utilizing the average value of member forces at each node, shared by the elements connected to that node, contour plots are generated. However, this feature is not available in Envelope Type load combinations.
Avg.Nodal does not consider the simultaneity for the load case in which maximum member forces are displayed about all elements such as Moving Load Case, Settlement Load Case and Time History Load Case.
Avg.Nodal Active Only : The Avg.Nodal function is performed only for the currently active elements.
Components
Select the desired internal force component among the following:
Fxx : Axial force per unit width in the element's local or UCS x-direction (Perpendicular to local y-z plane)
Fyy : Axial force per unit width in the element's local or UCS y-direction (Perpendicular to local x-z plane)
Fxy : Shear force per unit width in the element's local or UCS x-y direction (In-plane shear)
Fmax : Maximum Principal Axial Force per unit width
Fmin : Minimum Principal Axial Force per unit width
FMax : Maximum absolute Principal Axial Force per unit width
Mxx : Bending moment per unit width in the direction of the element's local or UCS x-axis (Out-of-plane moment about local y-axis)
Myy : Bending moment per unit width in the direction of the element's local or UCS y-axis (Out-of-plane moment about local x-axis)
Mxy : Torsional moment per unit width about the element's local or UCS x-y plane
Mmax : Maximum principal bending moment per unit width
Mmin : Minimum principal bending moment per unit width
MMax : Maximum absolute Principal Moment per unit width (Larger magnitude of Mmax and Mmin)
Vxx : Shear force per unit width in the thickness direction along the element's local or UCS y-z plane
Vyy : Shear force per unit width in the thickness direction along the element's local or UCS x-z plane
VMax : Maximum absolute shear force per unit width (Larger magnitude of Vxx and Vyy)
1*Mxx+1*Mxy : Displaying the results for the combination of bending moments Mxx (or Myy) and torsional moment Mxy.
Wood Armer Moment : Displays Wood-Armer moments per unit width which is the combination moment of bending moment (Mxx or Myy) and torsional moment (Mxy).
Fvector : Representation of maximum and minimum principal force directions and the larger absolute magnitude at the centers of plate elements
Mvector : Representation of maximum and minimum principal moment directions and larger absolute magnitude at the centers of plate elements
Vector Scale Factor : Drawing scale and thickness for the vector diagram
Type of Display
Define the type of display as follows :
Contour : Display the forces/moments of plate elements in contour.
Deform : Display the deformed shape of the model.
Values : Display the forces/moments of plate 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 forces/moments of plate 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.
Cutting Diagram : Graphically display the internal forces of the plane elements along a cutting line or plane.
Value Option
When the contour display method is set to "Element," you can choose the Value display method. If the contour display method is set to "Avg.Nodal," the maximum value among the averaged results at the joints is displayed.
Max : Display the absolute maximum value among the forces of a plate element at node.
Element Center : Display the force at the center of a plate element.
(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 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.
