Ductility Factor (D/D1)
|
|
|
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: |

Upon executing the Inelastic Hinge > Ductility Factor (D/D1) Table function, Records Activation Dialog prompts. Click Note Ductility Factor(D/D1) Table (Lumped, Distributed) Elem: Element number Hinge Location: Locations where inelastic hinges are assigned. For Lumped Type, it displays as i, j, i & j, FX. For Distributed Type, it displays according to the number of hinges. Inelastic Hinge Prop.: Inelastic hinge property number Load: Time history load case D/D1: the ratio of the maximum deformation within the elapsed analysis time to the 1st yield deformation Time: Time at which the maximum deformation occurs Ductility(D/D1) Factor Table (Truss) Elem: Element number Hinge Location: Location of inelastic hinge Inelastic Hinge Prop.: Inelastic hinge property number Load: Time history load case D/D1: the ratio of the maximum deformation within the elapsed analysis time to the 1st yield deformation Time: Time at which the maximum deformation occurs Ductility(D/D1) Factor Table (Spring) General Link Prop. : General Link Property Node1, 2 : Node numbers connecting a General Link Inelastic Hinge Prop.: Inelastic hinge property number Load: Time history load case D/D1: the ratio of the maximum deformation within the elapsed analysis time to the 1st yield deformation Time: Time at which the maximum deformation occurs |
