column reinforcements

[hilmi]

In our attached project, there is a terrible difference between the reinforcements of the marked columns in the basement and the reinforcements of the columns in the ground floor.

 

[Levent Özpak]

The reason why the column reinforcements in the basement are excessive is the interaction between the foundation and the superstructure. S11-12-26-27 columns are free only cantilever foundations in the X direction. If these columns are connected with continuous foundations in the X direction, the design effects are reduced. (For example, S11-S13, S12-S17, S26-S31, S27-S36 columns can be connected to each other with continuous foundations) Apart from this; *The superstructure must define a continuous foundation under all vertical carriers in the interactive solution. (Tie beams are drawn under the P4-P5 panels) *It is recommended to model the elevator curtains as shells. - It would be appropriate to enter the upper rigid basement floor number as -2. Good work
