h1. Modeling Steps

Create steps

* Use the Quick Bridge template (File > New Model) to create a new bridge model with "a 'Conc. Tee Beam"' bridge -deck section.
via "File > New Model" using the Quick Bridge template.

Note that \\
\\
Please note that a single column represents the default interior bent, isas shown modeledin byFigure a1:

\\

* Select the frame element which representingrepresents the bent cap, and select all joints located on this element, as shown in Figure 2:

Use "align=center,border=0!

\\

* Use the Edit > Edit Lines > Edit Frames" menu command to break the frame element at its intersection with the selected joints.
\\
\\
ReselectRe-select the 6six frame elements created by dividing the original bent cap and using usethe "Edit > Extrude > Extrude Lines to Areas" menu command to extrude the bent cap into the wall. Enter \-31 for increment dz, 10 for numberNumber, and checkselect the "Delete Source Objects" option. This will create a wall of approximately the same height as was the height of the original column:

 the original column. The process is shown in Figure 3:

\\

* Select the bottom joints of the wall and assign constraints tousing the via "Assign > Joint > Restraints" option. The completed model is shown below:in Figure 4:

* Users may also model wall properties by changing the section properties for theof areas assigned to the wall to model the actual wall properties.
