Function
- Check the hinge status (Ductility, Deformation, Force, Status of yielding) resulting from the Pushover analysis in Contours.
Call
From the Main Menu select [Pushover] tab > [Pushover Results] group > [Pushover Hinge Status Results]
Input
Pushover Load Case Name
Select a desired load case, load combination entered in Pushover Load Cases.
Step : Specify the step for which the analysis results are to be produced.
Type of Result
Ductility Factor
D/D1 : Ratio of the displacement to the 1st yielding displacement at the corresponding step
D/D2 : Ratio of the displacement to the 2nd yielding displacement at the corresponding step
Deformation
Plastic Deformation : Plastic deformation (total deformation yielding deformation)
Note
Plastic deformation is displayed as zero before yielding.
Force
Status of Yielding : Hinge status for Bilinear/Trilinear type hinge.
Note
Based on the assigned yielding strengths in Define Pushover Hinge Properties, the hinge status is classified as follows:
- Bilinear : Linear, 1st Yielding strength, 2nd Yielding strength
- Trilinear : Linear, 1st Yielding strength, 2nd Yielding strength, 3rd Yielding strength
If the pushover hinge is a Distributed type, hinge status is classified by elements color. (Linear : Blue, 1st Yield: Green, 2nd Yield : Red).
Status of Yielding (FEMA) : Hinge status for FEMA type hinge.
Note
Hinge status is classified based on three levels of FEMA functionality.
- FEMA : Linear, IO(Immediate Occupancy), LS(Life Safety), CP(Collapse Prevention), Collapse
Status of Yielding (EC8:2004) : Hinge status for EC8:2004 type hinge.
Note
Hinge status is classified based on three Limit States of EC8:2004.
- EC8:2004 : Linear, DL(Damage Limitation), SD(Significant Damage), (Near Collapse), Collapse
Components
Select the desired member force component:
Dx : Axial component in the element's local x-direction
Dy : Shear component in the element's local y-direction
Dz : Shear component in the element's local z-direction
Rx : Torsional component about the element's local x-axis
Ry : Bending moment component about the element's local y-axis
Rz : Bending moment component about the element's local z-axis
Type of Value
Positive : Display the maximum positive displacement
Negative : Display the minimum negative displacement
Abs Max. : Display the absolute maximum displacement
Type of Display
Define the type of display as follows:
Contour
Display the displacement of the model in contour.
The ... Button
Ranges: Define the contour ranges.
The Customize Range... Button : Assign the color distribution range of contour. Using the function, specific colors for specific ranges can be assigned.
Note
Contour Range Max/Min values can be larger than the max/min output values. If the Contour Range values exceed the output values, they are entered at Rank 0 and Rank 11.
Number of Colors : Assign the number of colors to be included in the contour (select among 6, 12, 18, 24 colors)
Colors : Assign or control the colors of the displacement contour.
Color Table : Assign the type of Colors.
The Customize Color Table Button : 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 : Display the spacing for the legnd 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).
Deform
Display the deformed shape of the model.
The ... Button
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 nonlinear 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.
Values
Display the nodal displacements in numerical values.
The font and color of the numbers can be controlled in Display Option.
The ... Button
Decimal Points : Assign decimal points for the displayed numbers
Exp. : Express as exponential
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 for nodal displacements relative to the selected maximum or minimum value
Set Orientation : Display orientation of numerical values
Note
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.
Legend
Display various references related to analysis results to the right or left of the working window.
The ... Button
Legend Position : Position of the legend in the display window
Rank Value Type : Specify a type of values in the Legend and the number of decimal points.
Animate
Dynamically simulate the transition process.
Click the Apply Button then click Record to the right of the Animation control board at the bottom of the working window.
The ... Button
Animation Mode : Determine 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
Select 'Half Cycle' for the transient shapes of a structure and 'Full Cycle' for dynamically simulating vibration modes or buckling modes.
