Effect of the raft slab space on the Column Punching Perimeter

[qwerty]

Mr. İde, Doesn't the raft floor space corresponding to the column border affect the punching perimeter of the column? Is there a reason why stapling calculations are not made for curtains resting on raft foundation?

When the raft is basically the elevator shaft, we think that it will be sufficient to pretend that there is no gap and add at least the raft foundation thickness and reinforcement to the elevator shaft perimeter walls and floor. While considering these, we may look at the foundation only in terms of soil stresses and forget the punching effect of vertical elements or not consider it important. While experimenting with this, I encountered the situation I mentioned above while trying to create a floor space and examine the punching effect.

Mr. Ide, Doesn't the raft floor space corresponding to the column boundary affect the punching circumference of the column? Is there a reason why the punching calculation is not done on the curtains resting on the raft foundation?

The voids are not taken into account in the punching control. In this case, you can manually calculate the punching circumference according to the conditions specified in TS 500 figure 8.4. Considering the gaps in the calculation of the punching circumference and automatic punching control on the curtains are among our notes.
