During the plausibility check, Error 727 appears: "The line support of the type 'Wall in Z' on line No. ... has no connection to any horizontal surface." What should I do?


The line support type "wall" is actually intended for ceiling slabs that, for example, rest on a masonry wall with elastic foundations. Therefore, this tool is only allowed for horizontal surfaces. Spring stiffness of the wall is calculated and applied in the calculation.

If the surfaces are not in a horizontal position, the spring must be entered manually.

In order to use the spring stiffnesses of a wall as a reference point for your own entry, you can first define the wall and then unselect the "Wall" option: the determined spring properties stay in the text boxes and can be modified.
