Hello, In the project; *There is a small beam fragment formation at the intersection of beams K13-K15 and K02-K37. To prevent this, define the slab edges of D16 and D03 slabs within 1 cm. *Also, there is no knot point on the beams at the point where the floor edges of some balcony floors are connected to the beams. *It is appropriate to enter the upper rigid basement floor number -2. In the attached project, the above-mentioned situations were arranged in the basement and ground floor, and the ground floor was copied to the normal floors. Good work
