Is the following a viable project?

The attached project is a model designed to answer some questions in my mind. On the K5-K6 beams on the ground floor, the columns on the ground floor were placed on an upper floor by enlarging their dimensions. The questions in my mind are: - Is there a load on the K5-K6 beams from the column? So how does the IDE model this? - When we look at the earthquake reports, B3 irregularity is not visible. To create the B3 irregularity, for example in this example, we need to place the top column on a completely different axis. But again, in this example, when we check the geometry, there is no problem in the reports, even though it gives incorrect column placement for the S1 and S3 columns. In summary, can we ignore the geometry check? - Does this attached model get approval from the relevant control engineers as an implementation project?

Hello, - In the system you created, S1 and S3 columns on the 1st floor do not transfer load to the K5- and K6 beams on the ground floor. -Since the columns S1 and S3 on the first floor are larger than the columns on the ground floor, the theoretical points of the columns do not overlap. Therefore, the first floor columns are connected to the ground floor columns with a rigid arm. The influences formed by this rigid arm are transferred to the columns on the ground floor. In order for the column to transfer load to the beam, the nodal point of the column must be at the same coordinate with the beam joint point. (As in b3.ide6) -Disaster Regulations (Article 2.3.2.4 a) does not allow such systems. Good work

Thank you for your interest, Mr. Levent. But on the system I am posting, reports say there is no B3 irregularity. If the control engineer system does not notice, this project can easily pass, right?

Mr. Levent, thank you for your interest. But in the system I sent, the reports say that there is no B3 irregularity. If the control engineer does not notice the system, this project can easily pass, isn't it?

Dear Fmwaral, About this What I can say is that the regulation does not allow this type of B3 irregularity, and the larger size of the column in the upper floors creates a problem in terms of implementation.
