beamless slab flooring (cork)

[TheBEaST]

These are the questions that come to my mind about cork flooring 1-) Would it be more accurate to define the reinforcement as reinforcement at the bottom-top or as flat+pile? 2-) Should we choose semi-rigid diaphragm or fully rigid when analyzing? 3-) What should be the min reinforcement thickness? 4-) In the selection of reinforcement, would fi8 be sufficient for reinforcement or would it be more correct to use fi10 or fi12? 5-) In the seismic load calculation method, should the modal contributions be combined or should the element-specific results be selected? 6-) Is it a suitable system for the 1st degree earthquake zone?

Hello, 1) Since there are no beams in the slab without beam, the horizontal loads are transferred to the curtain-column with the slabs. Reversible moments must also be taken into account. Just like the foundation, top and bottom flat reinforcement should be made. 2) Make sure to solve the semi-rigid diaphragm and add the tiles to the analysis model. See item 1. 3-4) Whatever the need is, the diameter becomes. But based on my experience, I am telling you that your slab floor thickness without beams is a minimum of 22-27 cm at a distance of 6-8 m. This flooring requires Q12/20 upside-down excluding additions. I recommend you to read the minimum thickness control and minimum column-wall thickness controls in TS500 for non-beam slab floors. You should also pay attention to the minimum reinforcement ratio in the floors. 5) It's all about your structure. In cases where the floor forces cannot be affected by the floor mass center, it may be necessary to transfer earthquake forces to each element mass separately. It will be an extreme example, but when analyzing a stadium structure, for example, you cannot collect the floor mass at one point. ideCAD checks each floor one by one and automatically changes the method when it detects a geometry that cannot be collected in a single point. 6) If what you mean by conformity is whether it is allowed or not, you can find out from the earthquake code articles 2.5.1.4, 2.5.1.5 and 2.5.1.6. If you ask as a recommendation, it can of course be done if there is enough curtain ratio and enough attention is paid to the manufacturing details. It is important to detail the curtain combinations correctly, as the floors come to the fore.
