Select the pier model type.

An idealized pier model is defined by a simple idealized boundary condition as defined on the Connections page.

A physical pier model is defined by the physical attributes of the pier including its material properties, cross beam, and column arrangement.

Material Properties

Define the material properties of the cross beam and columns.

Item	Description
f'c	Concrete strength
Ec	When checked, enter the modulus of elasticity of the concrete. Otherwise, the modulus is computed from the AASHTO equation
[More Properties...]	Edit additional concrete properties. Pre-defined concrete can be retrieved from the library using this option.

Pier Cap Dimensions

Define the dimensions of the pier cab or cross beam.

Enter the dimensions is the various fields as defined by the schematic show on this tab.

Define the layout of the columns.

Item	Description
Base of column	Define how the base of column is located.
Longit. Base Fixity	Define the fixity of the base of the column for longitudinal plane frame analysis.
Column Grid	Define the columns (see below for more information)
Locate the columns	Use these controls to transversely locate the columns (see below for more information)

Define the columns in this grid

Item	Description
Height	Height of the column
Bottom Elevation	Bottom of column elevation
Transv. Base Fixity	Define the fixity of the base of the column for transverse plane frame analysis. This analysis is not performed by PGSuper, however this information is used by the XBRate cross beam load rating application
Shape	Select the cross sectional shape of the column
Diameter/Width	Enter the diameter of a circular column or the width (dimension in the plane of the pier) of a rectangular column
Depth	Enter the depth (dimension normal to the plane of the pier) of a rectangular column
S	Enter the center to center column spacing

The columns must be located transversely in the plane of the pier.

Item	Description
Column	select a column to locate.
Offset	Enter the offset of the selected column from the selected datum
Datum	Select the datum from where the column location is measured.
