Function
This is a dialog box to automatically generate a fiber model for the inelastic analysis.
To create a fiber model, the location of the reference section and mesh size are set in this dialog box.
Call
From the Main Menu select [Properties] tab > [Inelastic Properties] group > [Inel. Control Data] > [Inel. Control Data]
Input
Reference Location for Distributed Hinges
For beam, a fiber model is created for the cross section selected among i-end, middle, and j-end.
*Columns and walls are created with the middle section.
Fiber Model Option : Beam-Column
Set the number of divisions for automatic generation of the fiber model.
Enter the numbers in core(confined area) and cover(unconfined area) respectively.
Fig. Auto-generation of fiber model
Fiber Model Option : Wall
Set the number of divisions for automatic generation of the wall fiber model.
"Consider Out-of-plane Nonlinearity of Plate type" : If out-of-plane stiffness in nonlinear analysis is not considered, the y-direction of the cross section is not divided..
"Fiber Areas"
- Auto Size : Automatically generate the fiber model considering the location of the rebar.
- Equal Size : Automatically divides into equal intervals.
