This example describes the entry of piers for a 3 simple span superstructure previously entered into BrD as part of
the Alabama BrD superstructure training session. This example is part of the design portion of the training where
users attempt to enter data on their own instead of following screen by screen captures. As such this example does
not describe data entry for each window. Instead it shows only certain windows and describes important modeling
concepts on these windows.
Locating Substructure Units
Open the bridge workspace for the PS 8 example and open the Bridge Alternative window shown below. The
reference line length is the length between the abutment bearings. The stating station is abutment 1 CL Brg station.

The substructure locations are defined as follows:
The individual Superstructure windows are shown below.

Revise the bearing types as follows:
Since this bridge alternative contains multiple superstructures you must specify the length of superstructure to load
for each pier. We are assuming both the fixed and expansion bearings carry the longitudinal forces.

The column geometry is defined as follows:
Enter the concrete column diameter as 3.5’ and neglect the steel casing.

We checked Developed at Start to assume actual length of drilled shaft below point of fixity provides enough length
for bars to be developed.
