Deformed Shape

 

 

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.

Note

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.

 

 

 

From the Main Menu select Results > Results > Deformations > Deformed Shape.

 

 

 

     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.

Note
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.

Note1.
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.

Note2.
Above items become activated only when time history analysis has been performed. 

 

 

Components

Select the desired deformation component among the following:

DX: Displacement component in GCS X-direction

DY: Displacement component in GCS Y-direction

DZ: Displacement component in GCS Z-direction

DXY =

DYZ =

DXZ =

DXYZ =

 

Local (if defined) : Where nodes are defined with local coordinate systems, displacements are produced with respect to the local coordinate systems.

 

Type of Display

Assign the type of display as follows:

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 displacement display

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

Real Deform: Display the detail deformed shape including the calculated displacements along the sections between the end nodes in addition to the nodal displacements for beam elements.

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"

Undeformed

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.

Values

Display the nodal displacements 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 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.

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 then click Record 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

Note
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 the animation window.

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

: 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.

Note

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.
