Function
- Check the Deformed Shape of the model.
- When the pushover analysis or the time history analysis is completed, check the deformed shape of the model for each time step.
When the pushover analysis is carried out using the inelastic general link elements (Spring Type), the yield status of the general link elements are displayed in the Legend along with the percentage of the hinge status level.

Input
Deformed Shape dialog box
Load Cases/Combinations
Select a desired load case or load combination.
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.
Displacement : Display the maximum deformed shape of the model. (Activated after time history analysis).
Velocity : Display the maximum nodal velocities of the model. (Activated after time history analysis). The magnitudes of the velocities are diagrammatically represented as if the values were displacements.
Acceleration : Display the maximum nodal accelerations of the model. (Activated after time history analysis). The magnitudes of the accelerations are diagrammatically represented as if the values were displacements.
Absolute Acceleration : Display the maximum nodal absolute accelerations of the model. (Activated after time history analysis). The magnitudes of the absolute accelerations are diagrammatically represented as if the values were displacements.
Difference between '(Relative) Acceleration' and 'Absolute Acceleration'
Acceleration (Relative) = Acceleration (Absolute) + Observer's Acceleration
As seen from the above expression, Relative and Absolute accelerations differ depending on the presence of Observer's acceleration.
Above items become activated only when time history analysis has been performed.

Type of Display
Assign the type of display as follows:

Deformation Type
Select the type of display for displacement
Nodal Deform : Display the deformed shape only with 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"

Overlap the undeformed and deformed shapes of the model.
The type of display for the undeformed shape of the model can be controlled in Display Option.

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.

Element numbers pertaining to the maximum and minimum forces are displayed.
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 forces/moments of plate elements.
Click the Apply button then click Record button to the right of the Animation control board at the bottom of the working window.
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
Select 'Half Cycle' for the transient shapes of a structure and 'Full Cycle' for dynamically simulating vibration modes or buckling modes.
AVI Options : Enter the options required to produce 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 (3~300) : Number of frames to simulate a 'Half Cycle'
Frames per Second (5~60) : 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
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.
Half Model Mirroring
Quarter Model Mirroring
Mirror by : Specify the mirror plane (s) by designating a plane and a coordinate in the direction perpendicular to the plane in GCS.
Hinge Status
The status of hinges formed by Pushover analysis is produced.
Current Step Disp.
Produce the displacements pertaining to the selected step of the construction stage if a construction stage analysis has been performed.
Stage/Step Real Disp.
Display the Real Displacements for each construction stage when the construction stage analysis is performed.
Real displacement is relevant only for construction stage analysis. To illustrate real displacement, a cantilever is constructed in 3 stages as shown below. Node 3 is activated at the stage 3, and the deflection δ33 occurs due to the self weight of the segment 3. But when constructing steel girders or PC girders, the virtual displacements δ31 and δ32 occur at the stage 1 and stage 2 respectively. Real displacement is the summation of virtual displacements, which occur before the corresponding node is even activated and net displacement, which occurs after the node is activated. Real displacement corresponds to the fabrication camber.

Pushover Hinge
Hinge status : The status of hinges formed by pushover analysis is produced.
Element Yield Status : The yield status of components (Fx, Fy & Fz, Mx, and My & Mz) by pushover analysis is produced. This option is useful in verifying if a shear failure occurred in any element.
Checking the Pushover Analysis Results
The deformed shape resulting from the pushover analysis can be checked for the following two cases:
1. When the hinge is assigned to a member
2. When the hinge is assigned to a member and general link
Hinge Status For FEMA Type hinge : For FEMA type hinge, the hinge status will be produced according to the hysteresis curve that is defined at Design > Pushover Analysis > Define Hinge Property. For general link hinge, the hinge status will be produced according to the hysteresis curve that is defined at Model > Property > Inelastic Hinge Property.
Hinge Status for Multi-linear type hinge : The pattern of the hysteresis curve defined at Design > Pushover Analysis > Define Hinge Property for Multi-linear Type hinge is the same as that defined in Model > Property > Inelastic Hinge Property for general link hinge. Therefore, the same hinge status is produced.
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.
