Function
- Enter the section effective stiffness of all beams/columns/walls in the analysis model at once.
- This is a convenient function that allows you to collectively input the effective stiffness for each member of bending/shear/axial force components using Section Stiffness Scale Factor/ Wall Stiffness Scale Factor function.

Input
Fig. Generate Section Effective Stiffness Dialog
Factors for Effective Stiffness
Specify the factors for effective stiffness
Bending(EI) : Iyy,Izz component
Shear(GA) : Asy,Asz component
Axial(A) : Area component
Note 1
Note 2
1.If there are already entered scale factors, all of them are deleted and replaced.
2.When the property of the wall is plate type, the bending and axial force components are adjusted at the same time, so the smaller coefficient among the two components of bending and axial force entered through the Generate Section Effective Stiffness dialog box is automatically entered.
3.For fiber sections, stiffness scale factor is not reflected in the analysis.
The Apply Button : Apply the entered value to the all beams/columns/walls.
The Close Button : Close the dialog box
Note 3
The automatically generated effective stiffness factors are applied in Section Stiffness Scale Factor and Wall Stiffness Scale Factor.
