Analysis Result of Fiber Section
Analysis results of fiber sections from time history analysis are displayed. The results consist of member force history of inelastic beam members modeled with fiber elements, stress - strain results of each section cell, and the state of fibers.
From the Main Menu select Results > Time History > T.H Results > Analysis Result of Fiber Section
Element
Enter a beam element number modeled with fibers. Analysis results of the fiber model defined within the element are produced.
Load case
Select a time history analysis case defined in Time History Load Cases.
Object for Plotting
Section: Plot the analysis results of the entire section of the selected element.
Fiber: Plot the analysis results of each cell of the selected element.
Position: Select the positions in the element local x-direction where the results are required. 5 Positions including i and j ends can be selected as shown in the following figure.
Type of Graph
Define the types of X and Y axis of the results output.
If Section is selected
X-axis can be defined for Dx, Ry, Rz, Fx, My, Mz, and Time. Y-axis can be defined for Dx, Ry, Rz, Fx, My and Mz. For 6 most frequently used combinations of components, selection can be made by the use of the buttons provided.

Display Cell Numbers
Note
Fiber Cells are assigned numbers according to the following rules:
Numbering order for materials: from Concrete Cell to Steel Cell
Numbering order for directions: 1. from left to right, 2. from up to down
Note
z and y axes displayed in the Fiber Section Animation window represent the element local z and y axes, respectively (looking at the member from the I-end of the member).
Fiber State
Specify the state of the output display for the fiber model.
Tension: Display the analysis results of the tension side.
Compression: Display the analysis results of the compression side.
Elastic, Crack, Yielding, Crushing: Select colors for each fiber state
Blending: Define the intensity of the display colors.
Time Step: Select a time history step at which analysis results will be produced.
: Initialize the fiber model.
: Plot the analysis results of the fiber model.
: Graphical data for analysis results can be saved in the Windows Bitmap (BMP) file format.
Fiber State definition is different for reinforcing steel and concrete and for each material model. Definition of Fiber State is as follows:

Animation
Select the time history step at which the analysis results need to be produced.
|
Step: Specify the step at which the time history analysis results need to be displayed. If a specific step is entered, it moves to the step directly. Increment: Graphic output is produced and recorded at the specified increment. Time: The actual time of the loading corresponding to the current step is produced.

: It auto-generates the animated results of time history analysis. The interval of display is at the specified Increment.
: Pause Animation generation.
: Stop Animation generation.
: Moves to the first step of the time history analysis result.
: Move backward to the previous steps by the increment.
: Move forward to the subsequent steps by the increment.
: Move to the last step of the time history analysis results.
