The logic for defining the lower support of the ladder

Hello, we have designed an external staircase to the 2nd floor in a 2-storey project. I defined the upper support as a single side beam-flooring, and the lower support as a fixed support. Other edges are blank. When I make a definition in this way, the relative floor drift increases significantly, including the building stiffness center. A case with the definition of the stair lower support. I define an external continuous foundation under the stairs with a height of +47.5. The center of rigidity approaches the middle and the relative floor drift returns to normal, but when I look at the Z-direction deformation, the ladder does not seem to be supported on the foundation. What solution should I implement? I couldn't figure out the logic of defining the bottom brace of the ladder. Good work.

Hi, the construction behavior when the staircase is resolved together with the structure and its supports are arranged as a fixed support or attached to the structural element It is a normal and expected situation that stair edges are not directly connected to the foundation at the moment. Stair k You can define the basement curtain and the continuous foundation under it as in the example. Good work
