Pier Section Property Override [SIG]
Since seismic analysis requires sections to be updated with cracked inertia and the structure to be analyzed accordingly, this object can be used to override a section's properties, such as pier columns.
The inputs for this object include factors that will be multiplied by the section's Area, Shear Area Y/Z, Torsion Constant, and Inertia Y/Z values (found under Properties > Sections) when defined.
Section Overrides
Pier Column: Specify the modeled column whose properties will be overridden.
Stage: Specify the stage at which the column with changed properties will be considered for both FEM and design.
Section Area Factor: Define the area factor that will be multiplied by the section's area.
Section Shear Area Y Factor: Define the shear area factor for the Y direction that will be multiplied by the section's shear area.
Section Shear Area Z Factor:Define the shear area factor for the Z direction that will be multiplied by the section's shear area.
Section Torsion Constant Factor: Define the factor that will be multiplied by the section's torsion constant.
Section Inertia Y Factor: Define the inertia factor for the Y direction that will be multiplied by the section's inertia.
Section Inertia Z Factor: Define the inertia factor for the Z direction that will be multiplied by the section's inertia.
