Turkish Good day, I had a question. I solved two separate projects, a staircase with a landing beam and a staircase without a landing beam. There is no such tightening in the other project, where stirrups are tightened on the columns on which the ladder is supported, in the project with a landing beam. Doesn't the stair landing alone have a short column effect on the columns?

Short column on stair landing

Hello, Conditions related to short columns are automatically applied in the program as mentioned in the regulation. The situation in question here is the stirrup wrap region. If the height of your column is so high that the "stirrup middle zone" will not form, the program automatically performs stirrup compaction. In short, the program applies the sanctions specified in the tdy regarding the short column effect on columns where stirrup compaction occurs along the column height. Columns that do not apply stirrup tightening in your project are the columns that are excluded from this situation. If you are satisfied with the application of the short column conditions in the mentioned columns, you have the chance to say that this is the short column for that column. In this case, item 3.3.8 is applied for that column. If you apply a "semi-rigid solution", you will have taken into account the effects of the landing in the column. If you believe that the landing will have a short column effect, you should interfere with the column free height (ln) from the column properties and also say to the column "this is the short column".
