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 > Deformations > Deformed Shape.

 

Select Deformations > Deformed Shape in the Menu tab of the Tree Menu.

 

Click Deformed Shape in the Icon Menu.

 

 

 

 

Load Cases/Combinations

 

Select a desired load case or load combination.

 

Click to the right in order to enter a new load combination or to modify the existing one. (Refer to "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 highrise buildings 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.

 

 

  • Checking the Pushover Analysis Results

    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 and

     

    2. When the hinge is assigned to a member and a general link

     

    Out of the diagrams below the first one corresponds to 1 and the second & the third correspond to 2. (In case when a general link is not defined, the hinge status for general link is not produced.)

     

    FEMA Type Hinge

     

     

     

    FEMA Type Hinge + General Link Hinge

     

    Hinge Status: 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.  

     

     

     

     

    Multi-linear Type Hinge + General Link Hinge

     

    Hinge Status: 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.

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 zero.

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.

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.

Assign a Base File Name under which the types of results (selection data in the Batch Output Generation dialog box for graphic outputs) are stored. 

Specify the Base Files to perform Batch Output Generation, construction stages, load cases (combinations), steps, etc. in the following dialog box.
