Hello brother, first of all I would like to say good luck. What I want to say about your project; 1. Is there a need to make a stud beam in ribbed flooring systems unless it is necessary? For example, if you add a single beam to column s02 and s06, the same goes for s03 and s07. 2. Aren't some column dimensions more than necessary, and the width of the supporting beams less than necessary? 3. How about you run the rib in the other direction for tiles d1,d2,d3,d4,d5? because in this way it will be very difficult to implement. It is not your mistake, but there will be problems in the application and it will not be applied properly. *As for the soil values, analysis-analysis settings-base soil section, soil unit weight, bed coefficient and soil safety factor are entered according to the soil survey. We also determine the floor class from the option Specify the soil type & response spectrum. Accordingly, TA and TB are also determined. I wish you good work.
