Function
- Check the ductility factor by using the ratio of the inelastic hinge deformation resulting from the time history analysis to the 2nd yield deformation specified by the user in a spreadsheet table format.
- D/D2 is the ratio of the inelastic hinge deformation resulting from the time history analysis to the 2nd yield deformation specified by the user.
- Table Tool in midas Civil offers a variety of powerful built-in functions. Refer to Usage of Table Tool for detail directions:
Call
From the main menu, select [Results] tab > [Type : Time History Analysis] > [Table] group > [Result Tables] > [Inelastic Hinge] > [Ductility Factor(D/D2]
Input
When the Ductility Factor (D/D2) function is executed, the "Records Activation Dialog" is called. Here, you select the load conditions and then click the OK button to generate the table for all targets. Depending on the case, it may take a considerable amount of time.
Please refer to the usage instructions of Table Tool to check the following data.
