Modeling 2 way PT in the longitudinal direction and one-way mild in latitude direction

Question

I have a system with long-span PT girders in the longitudinal direction. Mild reinforced joists run perpendicular to these girders in the latitude direction. The slab is mild reinforced.

I am trying to model these into RAM Concept and was wondering if the best way to do this is as follows

For the strips in the longitudinal direction (along the PT girders)

For the strips in the latitude direction (perpendicular to the PT girders)

I appreciate your guidance regarding this. Thank you.

Your settings look right to me. The latitude strips will be fairly narrow, but that's fine. You might have to adjust the "consider end 1/2 as supports" and support width settings to the width of the PT Girder. See: https://communities.bentley.com/products/ram-staad/w/structural_analysis_and_design__wiki/4507/ram-concept-design-strips-tn#beams 
 In the longitude direction, some users like to use the "Design column strip for CS + MS resultant".

I have not seen one like that. If the code has some provision for T beams based on the slab depth, the program might be thrown off by the secondary beams. Regardless, just model in a manual column strip boundary on each side to proceed.
