I can't attach beams to elevator curtain

In my attached project, I cannot connect my beams to my elevator curtain (K63-K70), do I need to do something on the stairs, can you check my project? What are my mistakes?

Hello there; You have serious mistakes in defining the beams in your project. Let me try to explain the points I marked in the screenshot below. 1- The reason why your beams are not connected to the elevator curtain is that the divide by intersections command is turned off while defining your beams. In this case, the beam will not divide the panel object to which it is attached (it will not be able to create a nodal point to which it can be connected), so it will not be attached to the panel. 2- While the part of the beam after the P13 curtain, as it is in the K21 beam, should have a different name, that is, an independent beam that accepts the P13-P15 panels as a support, the P12-P15 beams are designed as a single beam that accepts the support. 3- Another problem that I marked in the screenshot is that there are beams that are incorrectly defined on top of each other (at the same level). (Like K15 and K90) 4- You wanted to define the supports of your stairs in a way to transfer loads to the carrier system, but you caused the parts of your ladder that cannot be supported to be connected to the carrier system elements at far distances. You should model your ladder in a way that it will be supported by the carrier system elements it contacts from the edges that I have marked with blue lines in the picture below. What you describe is definitely wrong.
 
How did you see where the ladder is supported? In the help for solution with structure Support conditions for solution with structure: If the solution is made with the assumption of semi-rigid diaphragm, the structure - the ladder are solved together as a whole. In this case, the objects to which the stair edges are connected are determined by the options given in the dialog. Attached to beams, columns, panels, slabs, foundations: Determine which objects the stair edge is to be considered attached, respectively. Fixed support: Stair edge is considered as fixed support. Bracing distance: Give the amount of distance that will be valid for the stair edge to be attached to the support. is written. Could Ide officials explain this a little more? For example, what happens if we click on the fixed support.

Attached to beams, columns, panels, slabs, foundations -> Supported edge ; attached to beams, columns, panels and/or slabs and only as much as and together with their displacement. It means that it can move... Fixed support -> It means that the edge of the stair cannot make any displacement. Bracing distance -> It means that the edge of the stair can be attached to objects that are less than the entered distance value. (For cases where the side of the stairs does not physically coincide with the beam, column, slab and foundation objects)
 
For example, how should data entry be done if it is requested to be solved together with the structure for the attached project?

Stair supports can be arranged as the 2m Project stated in the message above.

4- You wanted to define the supports of your stairs to transfer loads to the carrier system, but you caused the parts of your ladder that cannot be supported to be connected to the carrier system elements at a very far distance. You should model your ladder in a way that it will be supported by the carrier system elements it contacts from the edges that I have marked with blue lines in the picture below.

When we use the Set support conditions command, the entire edge of the staircase is selected, how can we enter the information of only the support along the column, as determined by the 2m project?

It is not a problem to select the entire edge of the staircase in the program. A support distance is given.The edge of the stair outside this distance will not be supported on the relevant element.
 
Hello there; To divide the stair edges into parts according to the support condition (to define new support regions): 1- We use the SUPPORT DEFORMATIONS command in the ladder toolbar 2- After the support deformations toolbar is opened, we can use the ADD PRIMARY NODE command to divide the existing ladder edges into equal parts and create new nodes at these points. We can create points. 3- We move these new node points that we have created to the desired location by using the BRACKET DEFORMATIONS command. (Like the column corner in the example project or the step that touches the beam) 4- Thus, we assign the support conditions we want to the new stair piece that we have created in the desired length and position by using the SET STAIR SUPPORT CONDITIONS command. I think it was self explanatory. Best regards.

Is the data entry correct for the staircase inside the D19 slab?

The lower edge of the stair is supported on the slab. The support is correct if there will be another floor below the ground floor. However, if the ground floor is the lowest floor, this In this case, the lower edge should be supported on the foundation or defined as a fixed support. In addition, the upper left edge of the staircase is supported on the curtain column P01. Since the length of the column provides the ratio of 1/7, it is solved as a curtain. In this case, it would be appropriate to define the stair support as a panel.
