Select Code Check Template as SuperstrCCT.
...
Switch to Reinforcement input column.
...
...
Select Input Data Preference as Lumped in 1st row.
...
For Deck Rebar Material column, click A615_60, if not defined click Import.
...
...
From Database drop-down menu, select Steel Material Database.
...
...
From Category drop-down menu, select Reinforcing Steel.
...
From Asset drop-down menu, select A615_60 and click Import.
...
Drag down the imported material to the 2nd and 3rd rows.
...
...
Enter reinforcement area values specified in the corresponding cells. (Note that based on the input data preference, inputs not applicable automatically turns into N/A).
...
...
Switch to Stiffener input tab.
...
...
Select all Has Long. Stiffener column cells at once. Set its value to NO.
...
Select all Has Trans. Stiffener column cells at once. Set its value to YES.
...
...
Go to Stiffener Spacing Computation column.
...
...
For the code checks at span region, keep the value Use Cross Frame Spacing as default.
...
For the code check at support region, click three-dots icon, and select User Input.
...
See Transverse Stiffener Spacing column turned from N/A to a numeric value. For this example, keep it value 82 in as default.
...
...
Longitudinal stiffener = No for this example.
(Long. Stiff-comp. flange:= distance btw longitudinal stiffener and compression flange (in).)
