The 1st point is about freezing the beam direction.
Did you mean column?

I consulted my teachers at school. they said that something like this didn't happen, even if it did, they didn't know. so it doesn't make much sense to me. How can a column that doesn't save save when it changes direction?
The answer to this depends on why the column didn't save, and for what reason it saved after returning it. For example, rotating the column often works if the column is not recovering due to column-to-beam shear safety. However, for a definitive answer, it is necessary to examine the element results in detail. In short, a result may not always be valid because the column does not necessarily save when returned. It may or may not recover depending on the shape of the carrier system and the results of the analysis and which investigation it did not recover. 2)

The 2nd point is about the column header. Let's say that in some columns of a structure that we have solved with a 45 cm raft, a Z error, that is, a stapling problem occurs. When we add a column header to that column and the elevation of this header is equal to the base thickness In our work, there is no change in the basic application, neither as a drawing nor as reinforcement. When I saw a stapling error at school, either the floor thickness had to be increased or reinforcement should have been placed in the stapling area to save stapling. But this does not happen?
In the program, the punching verification is done only on the basis of the strength of concrete. Therefore, if the raft element does not have a punching head, the punching height is the same as the raft height-concrete cover. There are two solutions for a column with a punching error. Either you increase the thickness of the raft or you make concrete reinforcement with the punching head. If you enter a punching head into the raft, the head, column and raft plate In this case, the punch height is height+stapling head height-increases by the concrete cover. Therefore, as your stapling strength increases, the column can pass the stapling inspection. Equipping the punching head is a separate issue. You should prepare the reinforcement detail drawings of the header yourself. 3)

The third point is about the upper rigid basement floor number. We define the basement when defining the floor in the floor settings, which is -1. If there is a basement in the building, why is there a building with a basement in the analysis settings? The upper rigid basement floor number becomes -2. My system does not come out clean when I say -1 and make a solution, but when I say -2 and solve it, the system starts to come out clean?
The upper rigid basement number is a relative value. In short, it depends on the floor number of your basement floor in general. Floor general In the settings, floors can be defined in any order. If you make a solid rigid basement, you also change the floor forces coming to it. You can see the differences when a floor is a rigid basement by examining the related articles in TDY. If you enter the rigid basement number differently than it should be, you will not make the model realistic. According to this, the system's recovery/non-recovery doesn't mean a real result, it just means the calculation result of the model you made. You are obliged to define it basement number according to the rules of the program in accordance with the real structure. For detailed information about the rules of the program, you can review the figure below. Good work...
