. Now I have finished my project. Dear Emrah YILDIZ, Levent ÖZPAK and unver... Thank you very much to each of you. I couldn't have done it without you. Attached is the final version of my project. I wish you good work.[/ quote] Dear Gökhan Yılmaz, *Your foundations on the I and E axis on the Ground Floor are connected to the columns and curtains. For example, the left support of TK41 is P01 and the right support is P02. But the foundation beam does not cover the curtains. Such an application will not happen. If the architecture does not allow, then those foundations are not covered at all. Don't do it. The elevations of the columns on the I and A axis on the ground floor should be entered as -80 cm. On the basement floor, the upper elevations of the relevant columns should be arranged as -80 cm. *My warning about the stair reinforcement axes was not taken into account. Also, I think we have kept the forum very busy on this subject. Review and finalize your project in the light of the information above.
