T-Beams are used to model both single T and double T beams. By default only the stems are considered for shear.
Flange
This section contains the width and thickness of the precast top flange. The full width may be entered with a joint gap if you want the true width of the concrete section to be used.
Stem(s)
In this section you will need to input the top and bottom widths of the stems, along with the height (as measured from the bottom of the top flange) and number of stems in the member. The stem spacing is also input here. Typically, the stems are centered about the flange, but you can offset the stems within the flange by unchecking ‘Center Legs’. If you do so, you will be prompted for the location of the first stem (which is assumed to be the left-most stem).

The inverted T section can be used to design both IT-Beams and L-Beams (if the eccentricity is used). This section by default assumes only the stem is used for shear and torsion, but options exist to enable the ledges for both.
Flange
The flange section contains all information about the bottom flange, including both ledges. The full width of the bottom flange is entered with the ability to vary the thickness of each ledge.
