I am including some of the answers I gave to the questions asked about Cork flooring before. Good luck with. If there are beams or beams on the floor and you will use the mushroom option again, you should use the column head for punching and test it. However, cork flooring has its challenges. While the load-bearing system only consists of floors and columns, chimneys and shafts usually pass through the bottom of the columns, which seriously damages the system. Sometimes, you may encounter misleading results. I suggest you be careful. * Please describe the gaps in the system. These gaps are very important for such systems as they can be adhered to vertical carriers and can be of substantial size. * Use such systems in structures where columns are arranged in a certain order. * Slab thickness may be insufficient. The program tests the slab thickness according to the slab length calculated by itself from the point where the reinforced concrete calculation axis passes. Therefore, the thickness may be insufficient. However, there may be columns in between within this distance. Therefore, I think that the thickness calculation should be tested according to the largest column span. * Since you have to introduce the ladder to the system and accordingly, you have to solve it as a semi-rigid diaphragm, you will enter the load into the system. * I definitely recommend you to reinforce the system with curtains in un-beamed floors. * After placing the foundations, I recommend you to solve the superstructure interactively. Since the frame is not formed, the importance of the superstructure interactive will show itself more. * If the rigid diaphragm is not in contact with a beam, the system automatically tests the punching of the beamless structure. Otherwise, you should examine it with a zero-size column header.
