Function
- Display the internal forces of plate elements along defined cross sectional lines in a graph.
- This functionality allows us to check the analysis results in a desired direction regardless of the element local coordinate system used in creating plate elements.
Call
From the Main Menu select [Results] tab > [Type : Analysis Result] > [Result Display] group > [Forces] > [Plate Cutting Line Diagram]
Input
Load Cases/Combinations
Select a desired load case, load combination or envelope case.
Click the ... Button 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.
Note 1
The Construction Stage applicable for the output of the construction stage analysis is defined in Select Construction Stage for Display or Stage Toolbar.
Note 2
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.
Cutting Line Detail
Define coordinate systems, which will become the bases for producing the internal forces of plate elements.
Name : Name of a defined cutting line through which a force diagram will be produced
P0, P1, P2 : Coordinates defining the coordinate system
The Add Button : Add the defined cutting line to the list.
The Modify Button : Modify cutting line data registered in the list.
Saved Menu-Bar Info's : Listed here are the Base Files. Select the Base File Names for Batch Output.
The Delete the Selected Button : 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.
PostCS 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
The Delete Button : Delete a selected cutting line registered in the list
Plate Force Options
Element : Display the contour using the internal forces calculated at each node of an element.
Avg. Nodal : Display the contour using the average internal nodal forces of the contiguous elements sharing the common nodes.
Avg. Nodal Active Only : Execute Avg. Nodal for only currently active elements.
Components
Select the desired internal force component among the following:
Fxx : Axial force per unit width in the x-axis direction defined by P0 and P1
Fyy : Axial force per unit width in the y-axis direction perpendicular to the x-axis of the plane
Fxy : Shear force per unit width of the x-y plane
Mxx : Bending moment per unit width about the x-axis defined by P0,P1
Myy : Bending moment per unit width about the y-axis perpendicular to the x-axis defined by P0,P1
Mxy : Torsional moment per unit width of the corresponding x-y plane
Vxx : Shear force in the thickness direction per unit width in the x-axis direction defined by P0 and P1
Vyy : Shear force in the thickness direction per unit width in the y-axis direction perpendicular to the x-axis defined by P0,P1
(a) Forces per unit length due to in-plane actions
(b) Moments per unit length due to out-of-plane bending actions

Define the plane and color for representing the graph.
Normal : Express the graph normal to the plate elements.
In Plane : Express the graph in the plane of plate elements.
Scale Factor : Define the output scale ratio.
Reverse : Express the graph in the opposite direction.
Graph : Produce the diagrams in graph windows.
The ... Button
Prompt the Plate Cutting Diagram Mode dialog box to determine the type of graph window.
Draw graphs
on separate panes : Produce a number of Plate Cutting Line Diagrams in separate graphs.
All in one pane : Produce a number of Plate Cutting Line Diagrams all in one graph.
X-Axis : Define the X-Axis of the graph.
Distance from Pnt 1 : The scale of the X-axis of the graph is drawn following the length of the cutting line starting from the first point.
Global X Coord. : The scale of the X-axis of the graph is drawn on the basis of the cutting line projected on the Global X-axis.
Global Y Coord. : The scale of the X-axis of the graph is drawn on the basis of the cutting line projected on the Global Y-axis.
Global Z Coord. : The scale of the X-axis of the graph is drawn on the basis of the cutting line projected on the Global Z-axis.
Value Output
Produce the output in numerical values.
MinMax Only
Produce only minimum and maximum values if Value Output is selected.
Note
The 'Cutting Line' option in Cutting Diagram of Plate force/moment and Plate Cutting Line Diagram differ in the following aspects:
1) When 'Cutting Line' of Cutting Diagram is executed after selecting 'Local' of Plate Force Option in Plate Forces/Moments,
In this case, the plate forces in ECS x or y axis can be obtained at the intersections between the plate elements and the Cutting Line at A, B, C & D. The limitation is that only a single force component or contour can be checked.
2) When Cutting Line' of Cutting Diagram is executed after selecting 'UCS' of Plate Force Option in Plate Forces/Moments
Similar to the case 1 above, the plate forces can be obtained but in UCS, which is defined in advance in the directions of force components of interests.
3) When Plate Cutting Diagram is executed, force components can be obtained in any desired coordinate system.
This eliminates predefining UCS as in the case 2 above. However, contour is not provided in this function.
