-Which is the most preferred method of influencing the wall load on the structure in hollow floor systems, which idecad gives reliable, economical and rational results? (ie the method used by you, our experienced colleagues, idecad users?) [/ quote] Actually, I answered this question above. But let me write a few more sentences. The regulation allows you to calculate by increasing the live load. However, with the developing programming techniques, you can make a more accurate load analysis by either giving a linear load or entering a wall. Of course, here the wall is the unit volume. It seems to be the most correct method to obtain direct loading by entering it together with its weight. The definition of linear load corresponding to the wall load is also not wrong at all. Here the factor of how you gain practicality comes into play. Of course, when you enter the wall object, the visuality comes to the fore and less There may be a margin of error.If you are going to draw a section etc., the wall object is included. As n, you can enter the spaces more clearly into the wall. It is up to you to choose them by evaluating how much they will affect the overall project. N. YILMAZ
