Good day As we know, we need to meet some conditions in order to make ribbed flooring in Tbdy 2018. As an example, the building in the parcel with DTS 1 must also have a curtain, etc. A few projects and the company that we supply hollow filling material to today said, "We are supplying styrofoam according to the new earthquake regulations today," he said, "We are making it in 25 cm height 70X70 size," he said. Do you think it is correct to define this structure as a cassette slab when there are 70x70 double ribs in a 10 cm slab in both directions? In my opinion, in the regulation, double-sided rib laying and cassette laying should be distinguished. According to this situation, cassette laying and structures without curtains continue to be built, the case of rib laying ends, no one wants to do it under these conditions. What are your thoughts on this situation? In my own opinion, I think it is not correct to accept double-sided rib flooring as a cassette. Respects
 
Hello there; Cassette is the name of the formwork system used, and Hollow is the name of the filling material generally used for unidirectional gear floors. Over time, bidirectional slabs began to be referred to as cassette slabs, and single directional gear slabs as hollow floor slabs. Tbdy2018, on the other hand, penalizes gear floors working in one direction as they do not have the necessary in-plane rigidity in both directions. It does not apply any special sanctions for floors that work in two directions (cassette). The regulation equates cassette floors with beam systems. You can get information about this and similar issues by watching the recordings of the seminars made by the teachers who prepared the regulation on the youtube channel of the imo istanbul branch. Zekai Celep mentioned this issue in detail in his presentation. Best regards. Sent via iPhone using Tapatalk
 
Hello, We also thought of producing a project with the same logic, but I was surprised that the filler material manufacturer kept up so fast :) There is no obstacle in producing projects in this way. The main thing here is that the slab must provide sufficient rigidity in both directions, and 10 cm slabs and bidirectional ribs are quite sufficient in 70x70 cm opening. The framing of the beams depends on their rotational capacity at the nodes. This capacity increases as the beam depth increases and the frame behavior becomes ideal. But unless the regulation says that the height of the main beams in the beam plate system should be at least 45 cm, no one can object to this. Think of it this way, we can call a system with beams 36 cm high and 12 cm floor thickness as beamed plate. You will most likely make beams 32 or 35 cm, my advice is to keep the width of these beams to a minimum.
 
hello, with 70X70 pools and 10 cm plate, our system will be very heavy and the earthquake force in the structure will be high and our vertical carriers will swell. Companies will see that they are wrong in this choice, no one creates 70/70 pools easily. I am making a solution by using 100/100 pools and 10 cm plate (100/100 pools are formed by placing two 50/100 foams side by side. When some side openings are short, a single foam is put into production comfortably). In addition, in our regulation, the pool spacing is defined as 70 cm hollow space. ts500 11.3.1. The 70 cm limit was also brought. As I understand it, the system is hollow floor slab up to a 70 cm eye gap, whether it is one-way or two-way.
 
Hello, in order to be exempt from the requirements of the regulation regarding hollow floor flooring, it would be correct to consider cassette (grill) beam flooring by making double-direction gear flooring, as the phrase in practice (this term is also in the literature). I am of the opinion that it will not. Here is the criterion; tooth width, tooth height and tooth spacing should be decisive. Generally, we do 40 cm intervals, 10 cm wide, 32 cm high gear flooring working in one direction. Now, how accurate is it to evaluate the system in the cassette flooring class by making teeth in both directions with the same dimensions? But the regulation specifically said in one direction, if it happens in two directions, do we need to meet the same conditions or how we will evaluate it, of course. After all, it is a matter to be confronted by the controlling authorities. When we look at the legislation: In TS 500 (Article 11.3/11.5), gear laying conditions that work both in one direction and in both directions are the same. Teeth spacing e<=70 cm, tooth width bw>=10 cm, plate thickness t>=1/10e, 5 cm In TBDY2018, it is said that the plate thickness will not be less than 7 cm in geared upholstered systems. (no information about tooth width, tooth spacing) When we look at the literature (floor classification): "Toothed (ribbed) flooring: Interdental can be filled or unfilled. Teeth can work in one or both directions. Width of teeth 10-15 cm, height 25-35 cm, plate thickness is 5-7 cm. Cassette (Grid) beam flooring: It is built like a toothed flooring. Normal sized beams (secondary beams) are used instead of teeth. Secondary beams fit on the surrounding main beams. Main beam width is 80-100 cm. The distance between the secondary beams is around 50-150 cm. " I think it would not be correct to evaluate the result as cassette flooring by making 10 cm tooth width and 32-35 cm tooth height in 70 cm intervals in both directions. This system is gear flooring working in two directions. It is clear that a toothed floor running in two directions will behave more rigidly than a toothed floor running in one direction. But; It is a system cassette flooring, which is formed with secondary beams at 120-150 cm intervals, 20-30 cm wide and 50-60 cm deep.
 
Hello, there is no clear view, as in other articles of the regulation. I researched a little more, I thought, in order to be able to find a solution as a cassette floor, it is necessary that the secondary beams distribute the loads equally in both directions. When Idecad creates a slab with the cassette command, it distributes the load equally. In this case, my opinion for the cassette flooring design is to create a thickness of 35 cm with a slab thickness of 120 * 120 * 25 in size of 120 * 120 * 25, and if the thickness of the secondary beams is too thick, it is also useful to keep it at a minimum, since the load will be too much. I have come to the conclusion that it can be done. Thanks for sharing your knowledge and opinion. Maybe this thread will help others. Respects.
 
The TS500 has limited the spacing between the teeth to a maximum of 70 cm, regardless of single or double-sided slabs. Therefore, I believe that more than 70 cm tooth spacing cannot be made. The flooring defined as cassette in İdecad is bidirectional gear flooring. Apart from this, the solution we made by defining classical beams and slabs in both directions is the beamed floor solution.
 
A 20 cm gap is left on the edges when laying hollow blocks. It is not written as a tie beam either. Can you write the steps made in the idecad program while making 25 cm hollow floor tile? I don't know how to throw the tie beam
