Turkish Hello, In my system with 3 curtains in Y direction and only 1 70/30 column in the same direction, with group curtains and 2 extra curtains in the x direction, the results of 4.3.4.6 check are as follows, is it normal? Can't it go above 0.75 in this system with so many pitches.

I have the same problem too. After all, it is a 4-storey hollow building. I think the 0.75 limit should be reconsidered here..... I solved the attached project with 30/60 columns only before. Now I'm scared of the result.. According to this regulation, what we did before will be destroyed in the hollow system.. This is an over exaggerated coefficient.. easy.

Hello, In your project, enter the columns on the elevator perimeter curtain as panels and include them in the curtain group. After doing this, the overturning moment You can observe that the ratio has increased from 0.18 to 0.35. The cork flooring system was selected in the analysis wizard. I think you wanted to make mixed and hollow blocks. Adjust the selections in the analysis wizard accordingly. The curtains in the Y-direction corner do not contribute much to the tipping moment. In order to provide the best, it is necessary to consider more core curtain systems.In this context, you may need to review your carrier system. It allowed the bending moment contribution of beams connected to the holes in-plane to be taken into account, but this requirement was removed in 2007 and is absent in the TBDY 2018 regulation. TBDY 1998 regulation tipping moment article: The program performs tipping torque control as written in 2018 regulation. There is no programmatic error. This article of the regulation gives such results in terms of curtain overturning moments in small systems. These results give similar results with manual and constructor-sourced programs."myıldız25":2itddw1l" said:Hi, in my system with 3 curtains in the Y direction and only 1 70/30 column in the same direction, with group curtains and 2 extra curtains in the x direction, the results of the 4.3.4.6 check are as follows, is it normal? Can't it exceed 0.75 in this system with so many curtains..... Could this be a programmatic problem?
Mr. Hakan, I also have problems with this item in my project. I had a question, I would be glad if you answer it. A project can be made by using hollow block slabs and normal (slab) slabs together, in other words 25/50 beams (in the outer areas) and hollow-hole beams (in the inner areas), and you can select "Beamed or Cassette Slab type" for the floor type in the Analysis Settings Wizard. so that I can calculate by choosing high ductility instead of mixed structure ductility level?
Could you elaborate a little more on what you want to say, please? Can't I choose the slab type as "BEAM AND CASSETTE FLOORING" and use the high ductile calculation method by using hollow block and normal (beamed, slab) slabs together? Thank you very much in advance.

Hello In TBDY 2018, there is no explanation about what the flooring system will be chosen and the ductility level depending on this, if different flooring types are used together in the building. From the information you have given, it is understood that unidirectional toothed flooring is used quite extensively in the construction. (Or, by changing the flooring system, a solution with a high ductility level can be achieved. r.) Good work"vecih":1wmxl949" said:Hakan Bey, I also have problems with this item in my project.

Levent, first of all, thank you very much for your reply. I added my project to the link I gave. I would have two questions. 1-Beam OR CASSETTE FLOORINGS, high ductile and R=7 were selected from the Idecad Slab Type Wizard since I used both Hollow Hole and slab flooring in my project. Is such an analysis correct? Or would it be more correct to choose the flooring type as SINGLE DIRECTION GEAR FLOORING? (It becomes impossible to analyze because R=5 is the case with the Mixed system in single-sided slabs) 2- Defining two-way threads on hollow slab means cassette slab, or should we define beams such as 20*40 cm according to min beam conditions? Good luck..

Hello Vecih Sir, I gave the answer to your question in general in my previous message. I quote it again below. In addition, I can suggest you to get opinions from the relevant authorities."vecih":hx71femg" said:Levent, first of all, thank you very much for your reply.

2- Defining two-way threads on the hollow block means cassette flooring or should we define beams such as 20*40 cm, for example, according to the min beam conditions. Good work.
