Stairs influencing building analysis

[qwerty]

The reason why I ask the following questions, especially after clicking the analysis icon, the program says to check the geometry, but when we press the geometry check button, it says there is no error, and it shows the ladder with a red arrow in the analysis display options. And I understand that I am doing something wrong when creating the ladder and/or selecting the options related to the ladder. I would appreciate it if you could answer these questions in an explanatory way. 1-When placing the ladder in the building, should the dimensions of the stairs and the space left geometrically be the same? 2-Does it affect anything if the size of the stairs is larger or smaller than the area where it will be placed? 3- When I click on the ladder icon, is there any difference in which point I place the ladder by holding it? (Is it a priority to place it on the vertical element?) 4-Is this what I need to understand from stair bracing: If the stair reinforcement continues inside the relevant element (beam, slab, foundation, curtain, column) there is support. and I can say that this supported edge of the ladder (the edge whose reinforcement enters into the element with which it contacts) is prevented from being translated and rotated. However, if the edge of the ladder does not continue inside the relevant element (beam, floor, foundation, curtain, column) with which it contacts, I can say that translation and rotation are not prevented. If what I'm talking about is true: Detecting edges for the structure-independent solution is simpler. 5-But if I want to solve it with the solution option together with Yapı; For example, if I mark the stair support edge connected to the Beams, does the term Connected mean Rotation and translation is prevented? 6-Does it also mean that the fixed support option is prevented from turning and shifting, and when is it appropriate to mark it? It is defined as "Staying distance: Give the amount of distance that will be valid for connecting the stair edge to the support". 7-What does the support distance mean more clearly, 8-In which situations do I need to change it?

1-When placing the ladder in the building, should the geometrically empty space for the ladder and the dimensions of the ladder be the same?

2-Does it affect anything if the size of the ladder is larger or smaller than the area where it will be placed?

It should be noted that it is the same. Connection problems may occur if it is not placed correctly. If you are solving with the structure, it may affect the analysis model. For this reason, the ladder should be placed in such a way that it connects to the building elements.

3-Does it make any difference when I click on the ladder icon and from which point I place the ladder? (Placing priority on vertical element?)

No difference. The ladder can be held from a desired point and placed.

4-Is this what I need to understand from stair bracing: If stair reinforcement continues inside the relevant element (beam, slab, foundation, curtain, column) it is in contact with, there is support. and I can say that this supported edge of the ladder (the edge whose reinforcement enters into the element with which it contacts) is prevented from being translated and rotated. However, if the edge of the ladder does not continue inside the relevant element (beam, floor, foundation, curtain, column) with which it contacts, I can say that translation and rotation are not prevented. If what I have mentioned is true: It is simpler to detect the edges for the structure-independent solution.

You can say yes, but when the staircase is solved independently of the structure, the effects of the stairs on the structure are not taken into account.

5-But if I want to solve it with the solution option together with the Structure; For example, if I mark the stair support edge connected to the Beams, does the term Connected mean Rotation and translation is prevented?

No. When the staircase is solved together with the structure, for example, when it is connected to the beam, the finite elements of the staircase are connected to the beam with rigid arms and the system is solved together.

-Also, does it mean Fixed support option or does rotation and translation is prevented, and when is it appropriate to mark it?

Yes. This option can be checked if the stair edge is attached to a carrier element but is not defined in the model.

Defined as "Shoring distance: Give the amount of distance that will apply to tie the edge of the stair to the support". 7- What does the support distance mean more clearly, 8- according to which situations should I change it?

The support distance indicates how far the stair edge can be attached to the building element. For example, if you give 1 meter, it means the stair edge can be connected to the specified elements within 1 meter. This value is used to eliminate small distance differences between the edge of the stair and the element. For example, this value can be increased for elements that need to be supported on a wide beam.
