Do basement curtains contribute to the system?

[Ismail Hakki Besler]

Yes they do. They shorten the length (height) of the column or curtain to which they are attached. In some cases, they even affect the colon to the extent that it behaves like a short column. Basin curtains must be modeled in calculations and added to the system. Defining constructive can lead to erroneous results. If they are not connected to columns or curtains, they do not contribute to the system. However, when the basic and superstructure interactive solution is made, it is not enough to disconnect the sub-basement curtain from the column only; If the relationship with the raft is not interrupted, this basement curtain contributes to the raft as a kind of foundation beam. Therefore, it should not be entered constructively, even if it is disconnected from the columns.
