# Pier Section Property Override \[CUG]

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.
