Boundary Load Group Name
Boundary Group Name: Select a Boundary Group defined in Model > Group > Define Boundary Group. If a Boundary Group has not been defined, specify default.
Option
Add/Replace: Add new scale factors to selected elements, or replace previously defined stiffness scale factors.
Delete: Delete stiffness scale factors previously assigned to specific elements.
Scale Factor
Enter the required scale factors to be applied to each stiffness component.
I = J : Applicable only for tapered sections. Section Stiffness Scale Factors at I-end and J-end can be different.
Area: Cross-sectional area
Asy: Effective Shear Area resisting shear forces in the element local y-axis
Asz: Effective Shear Area resisting shear forces in the element local z-axis
Ixx: Torsional Resistance about the element local x-axis
Iyy: Area Moment of Inertia about the element local y-axis
Izz: Area Moment of Inertia about the element local z-axis
Weight: Cross-sectional area used for calculating self-weight
Add or modify reduced stiffness data of each member type in a spreadsheet format table.
Note
Copy & Paste and Edit the data in MS-Excel.
Composite Section
For sections defined as Composite Type, Scale Factors can be defined for Before (before composite action), After (after composite action) and All.
Before: In case of a composite section, the defined Scale Factor is used to calculate section forces and stresses before
composite action
After: In case of a composite section, the defined Scale Factor is used to calculate section forces and stresses after composite
action.
All: In case All (Before and After) is checked on, the defined Scale Factor is used to calculate section forces and stresses before
and after composite action
Note
When a ratio of Modulus of Elasticity for long term and shrinkage is defined in Section Data, the structure group for long term and shrinkage is automatically generated, and the applied scale factors for each are displayed
