Displacement Contour

 

 

Evaluate the displacements of a model by Displacement Contours

 

 

 

From the Main Menu select Results > Results > Deformations > Displacement Contour.

 

 

 Load Cases/Combinations

Select a desired load case, load combination or envelope case.

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 displacement of the model in contour.

Velocity

Display the velocity in contour.

Acceleration

Display the acceleration in contour.

Absolute Acceleration

Display the absolute acceleration in contour.

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.

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).

Disp.

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.
