Dear supplier. MY SUGGESTIONS: 1- You can get the building importance factor of 8, 2- For columns: it would be better to make a column with a pointed corner, it is difficult to manufacture. 3- Eliminate ZK errors by enlarging the columns, 4- Enlarge the beams, center the columns (maximum 35/2 cm out of the column Appendix: There is an incorrect (27 cm) condition in the MOLD PLAN) 5- Enter the ladder taking into account the support conditions, 6 - Check the wall loads, 7- If there is a wall on the floor, increase the live loads, 8- Is there an elevator tower? 9- The rigidity of the building is low, put earthquake curtains in both directions.
