Re: general report control Hello, Since you modeled the elevator curtain as a shell on the lower floors and as a bar on the upper floors, a discontinuity has occurred in the analysis model. Model it as a shell on all floors. Again, since the elevator curtain basically defines -20cm elevation, you need to give -20cm lower elevation in P1 and P2 curtains. Ø16 diameter was chosen because the reinforcement was insufficient in raft flooring. I recommend removing retaining bulkheads from the analysis model. In the formwork plan, it would be more appropriate to connect the columns with beams from column to column instead of at the cantilever end. The edited project is attached.
