Function
- Check the ductility factor by using the ratio of the inelastic hinge deformation resulting from the time history analysis to the 1st yield deformation specified by the user in a spreadsheet table format.
- D/D1 is the ratio of the inelastic hinge deformation resulting from the time history analysis to the 1st 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/D1]
Input
Upon executing Ductility Factor (D/D1) Table function, Records Activation Dialog prompts. Click OK button after selecting time history loading conditions for output. Clicking OK button will display the forces for all the loading conditions, and it may take long depending upon cases.
Refer to Results Table of "Usage of Table Tool" for the usage of Records Activation Dialog.
Refer to "usage of the Table Tool" and check the following data.
