r coefficient selection

[ERDZL]

Can you help in choosing the r coefficient in a reinforced concrete and steel project? I am getting a relative story drift problem. In the options, there is no option to carry reinforced concrete columns and beams and the effects of earthquakes, and how can I share the project with you?

The choice of A16 or C16 is suitable for the direction of the scissors. R and D coefficients are the same in both choices. There will be no problem. However, since the vertical bearing elements of its side are reinforced concrete, you can choose reinforced concrete and continue. The best practice would be as follows. First, make the appropriate selections from the analysis settings for the steel upper section. For this, the point that is the point will be C16, and the other direction will be C11. At the end of this selection, connect the beams to the weak axis, not jointed, but moment-transferring so that the steel section behaves correctly. Then do the analysis and complete the design so that the steel elements are checked for relative displacement and strength. Get the elective report. Then save the project as. Make the appropriate selections for reinforced concrete from the analysis settings. This time, the point of the scissors will be A16, and the other will be A11. Analyze. Do not touch the steel at all, only complete the design of the reinforced concrete elements. Again, get an optional report. Take the steel elements and the relative offset of the steel floor from the report of the first model and combine the reinforced concrete from the report of the second model. Note: Since your reinforced concrete and steel carrier systems have the same R and D coefficients, there is no problem in choosing a single model according to steel and continuing.
