Influence Lines - Plate Forces/Moments


  • Check the internal force influence line of a plate element.



From the main menu, select [Results] tab > [Type : Analysis result] >  [Moving Load] group > [Influ.Lines] > [Plate Forces/Moments]



Results-moving load-influence lines-Plate forces moments.png

Plate Forces/Moments dialog box


Line/Surface Lanes

Select a traffic lane for which the influence line analysis results are to be checked.

Key Element : Enter a plate element number, or click the entry field and the desired plate element in the working window.

Scale Factor : Enter the drawing scale factor for the influence line. This does not affect the influence line values.



Assign a position on the plane of the plate element within which the internal force influence line is sought.



Assign a desired component of the plate element's internal forces.

Fx : Axial force per unit width in the element's local x-direction

Fy : Axial force per unit width in the element's local y-direction

Fz : Shear force per unit width in the element's local x-y plane (In-plane shear)

Mx : Bending moment per unit width about the element's local x-axis

My : Bending moment per unit width about the element's local y-axis

Mz : Bending moment per unit width about the element's local z-axis


Type of Display

Assign the type of display.


1. Contour

1. Contour

Display the plate element's internal force influence line in contour.


Ranges : Define the contour ranges.

Customize Range... : Assign the color distribution range of contour. Using the function, specific colors for specific ranges can be assigned.

Number of Colors : Assign the number of colors to be included in the contour (select among 6, 12, 18, 24 colors)

NOTE.png The ability to specify Contour Range Max/Min values outside the range of the output values has been added. If the values are within the Min/Max range, they will be treated as before. However, if they exceed the range, the Min/Max values will be entered at Rank 0 and Rank 11.

Colors : Assign or control the colors of the contour.

Color Table : Assign the type of Colors.

Customize Color Table... : Control the colors by zones in the contour.

Reverse Contour : Check on to reverse the sequence of color variation in the contour.

Contour Line : Assign the boundary line color of the contour.

Element Edge : Assign the color of element edges while displaying the contour.

Contour Options : Specify options for contour representation.

Contour Fill

Gradient Fill : Display color gradient (shading) in the contour.

Draw Contour Lines : Display color boundaries in the contour.

Draw Contour Line Only

Display only the colored boundaries of the contour.

Mono line : Display the boundaries of the contour in a mono color.

Contour Annotation

Legend or annotation signifying the ranges of the contour is displayed.

Spacing : Specify the spacing of the legend or annotation.

Coarse Contour(faster) (for large plate or solid model)

Represent a simplified contour for a large model using plate or solid elements in order to reduce the time required to represent a complete contour.


Where plate elements or solid elements along a cutting plane are represented in contour, a three dimensional contour is created. The positive direction of the analysis results is oriented in the z-axis direction of the local element coordinate system.
The option is not concurrently applicable with the Deformed Shape option. Similarly, the option cannot be concurrently applied to the cases where the Hidden option is used to display plate element thicknesses or the Both option is used to represent Top & Bottom member forces (stresses).


2. Legend

2. Legend

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


Legend Position : Position of the legend in the display window.

Rank Value Type : Specify the output format and decimal places for the Legend values.


3. Values

3. Values

Display the internal force influence line in numerical values.
The font and color of the numbers can be controlled in Display Option.


Decimal Points : Assign decimal points for the displayed numbers.

Exp. : Express as exponentials.

Min & Max : Display the maximum, minimum values.

Abs Max : Display the absolute maximum value.

Max : Display only the maximum value.

Min : Display only the minimum value.

Limit Scale(%) : Set the screen display limit for internal force influence line values relative to the selected maximum or minimum value.

Set Orientation : Display orientation of numerical values.

NOTE.png The default Decimal Points can be controlled in "Preferences".
Set Orientation = 0 horizontally displays the numerical values to the right of nodes or elements.
The orientation angle represents the counter-clockwise direction, which may be used to enhance the readability of the numbers.


4. Animate

4. Animate

Dynamically simulate the variation of internal forces and deformed shapes due to the moving load.

Click Apply then click Record to the right of the Animation control board at the bottom of the working window.


Animation Mode : Select the type of animation for analysis results.

Animate Contour : Option to change the color of the contour representing the transition according to the magnitudes of variation.

Repeat Half/Full Cycle : Select the repetition cycle for the dynamic representation of the transition.

NOTE.png Select 'Half Cycle' for the transient shapes of a deformed structure and 'Full Cycle' for dynamically simulating vibration modes or buckling modes.

AVI Options : Enter the options required to produce the animation window.

Bits per Pixel : Number of bits per pixel to create the default window for animation.

Compressor... : Assign the method of compressing image data.

Frames per Half Cycle : Number of frames to simulate a 'Half Cycle'.

Frames per Second : Number of frames per second to present dynamic simulation.

Construction Stage Option : Select the animation options when the construction stage analysis is performed.

Stage Animation : Animations by construction stages.

Current Stage-Step : Animations by Steps in the current construction stage.

From ~ To : Starting and ending construction stages or steps for animations.


Include Impact Factor

Reflect the impact factor in the display.


Write to File...

Save the results displayed in the current model window as a text file.
