Inelastic Hinge Status dialog box


Select a Time History Result Function.

Time History Load Case Name

Select a time history load case entered in Time History Load Case.


Specify the step for which the analysis results are to be generated.

Time Function

Select a time history forcing function from the list.

Type of Result

Hinge Status 

The 5 levels of hinge status defined in inelastic hinge properties are displayed.

Ductility Factor 

Results calculated on the basis of the ductility evaluation method defined by the user in inelastic hinge properties are displayed.



Status of Yielding : Display Elastic, Crack or Yielding status.

NOTE.png When "Status of Yielding" in the "Type of Result" is checked, the Status of Yielding is displayed as one of the following four states depending upon the Yield Strength defined for the hysteresis model in Inelastic Hinge Property:
- Linear (elastic), 1st Yield (1st yielding), 2nd Yield (2nd yielding), 3rd Yield (3rd yielding)
For Distributed Type hinge, the Status of Yielding is displayed as an element color. For Lumped Type and General Link Type hinges, the Status of Yielding is displayed as a circular hinge.
If an element has several hinges and even if one hinge is under yielding state, the Status of Yielding is regarded as "Yielding".


Select a desired displacement component.

Dx : Displacement component in ECS x-dir.

Dy : Displacement component in ECS y-dir.

Dz : Displacement component in ECS z-dir.

Rx : Rotational component about ECS x-dir.

Type of Display

Define the type of display as follows:


1. Contour

Display the stresses of beam elements in contour.


Results-Time History-Inelastic Hinge Status-contour detail.png

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.

Extrude : 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. Deform

Display the deformed shape of the model.

Deformation Scale Factor

Magnify or reduce the size of the displacement graphically displayed in the model window.

Deformation Type

Select the type of display for displacement.

Nodal Deform : Display the deformed shape reflecting only the nodal displacements.

Real Deform : Display the detail deformed shape calculated along the sections between both ends of beam elements together with the nodal displacements.

Real Displacement(Auto-Scale off) : The true deformation of the structure is graphically represented without magnifying or reducing it. This option is typically used for geometric non-linear analysis reflecting large displacement.

Relative Displacement : The deformation of the structure is graphically represented relative to the minimum nodal displacement, which is set to "0".

Undeformed : In addition to the deformation, it displays the pre-deformation model shape.

The representation method of the pre-deformation model shape can be adjusted in the Display Option function.


3. Values

Display the internal forces of beam elements in numerical values.
The font and color of the numbers can be controlled in Display Option.


Results-Time History-Inelastic Hinge Status-value output detail.png

Decimal Points : Assign decimal points for the displayed numbers.

Exp. : Express as exponentials.

MinMax Only

Min & Max : Display the maximum and 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 to display inelastic hinge status whose values fall within the range of selected (Max or Min)*Limit Scale.

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. Legend

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


Results-Time History-Inelastic Hinge Status-Legend detail.png

The node numbers at which the maximum and minimum deformations occur are displayed.

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

Rank Value Type : The format of Legend values and the decimal point are specified.


5. Undeformed

Undeformed model shape is additionally displayed on the deformed shape diagram.

Display for the Undeformed model shape can be controlled in Display Option.


6. Animate

Dynamically simulate the internal forces of the beam elements.
Click Apply then click Record to the right of the Animation control board at the bottom of the working window.

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.

Center : Represents the internal forces at the center of the element.

J : Represents the internal forces at the ending node (N2) of the element.
