Curtain thickness, floor deflection problem and raft thickness

[statikçim]

HELLO, I HAVE SOME DIFFICULTIES WITH MY ATTACHED PROJECT. 1) RADYEM DOES NOT RESCUE 60 CM, WHEN I DO 70 IT SAVE. THE PROJECT IS SMALL AND TOTALLY 6 FLOORS IF WE COUNT ON THE BASEMENT. IS IT POSSIBLE FOR MY RADIUM TO BE 60CM? HOW SHOULD YOU FOLLOW POSSIBLE? 2) 1 OF MY FLOOR GIVES A DEPLACE LIMIT ERROR. DEFINITELY I DID NOT CASSET THE FLOOR AGAIN, IT WAS NOT FIXED. DO I HAVE TO DO SOMETHING OTHER OR IS MY TEETH WIDTH IMPOSSIBLE? 3) SHOULD I CONSIDER THE ERRORS IN FLOOR FLOOR AND MACHINERY FLOOR FLOOR FLOOR FLOOR AND MACHINERY FLATS, WHICH SAYS CURTAIN THICKNESS CANNOT BE LESS THAN 1/15 OF FLOOR HEIGHT IN GEOMETRIC CONTROL? 4) HOW DO I BUILD MY LADDER AND IS IT POSSIBLE TO MODEL THE LADDER AS A WHOLE WITH THE STRUCTURE?

Hello, I suggest you to perform analysis by ticking the "superstructure interactive solution" option in 1-Analysis Settings / Foundation soil tab. The calculation beam of the 2-D01 slab has come over the gap opened in the slab. Change the calculation beam with the set typical beam command. In addition, it is not recommended to define a gap to cut the rib teeth. The rib tooth works as a console. You can review the information on the subject in the link below.

3- Check TDY 2007 item 3.6.2.1. 4- Stairs can be created as described in the links below and the stair supports can be arranged according to the "solution with the structure" conditions in the picture and solved together with the structure.

Some other notes; - Hollow floors cannot be solved as a single console.

-Linear slab loads are not considered on beams. On the beam, wall load and live load can be entered in the beam settings, additional load can be defined.

-Linear slab loads defined on hollow slabs are not taken into account in the solution based on full rigid diaphragm assumption.

Thank you Mr. Levent, thank you for your answers. Problems 1 and 2 have been resolved, but

-Flying floors cannot be solved as a single console. did you want to or are you talking about the places in the picture below??? also I understood the following

-Linear floor loads are not taken into account on beams. On the beam, wall load and live load can be entered in the beam settings, additional load can be defined.

-Linear slab loads defined on hollow slab are not taken into account in the solution based on full rigid diaphragm assumption.

o How will it be when entering the wall load to the suspended floor? Another problem is the curtain thickness issue. I had studied the article 3.6.2.1 in the earthquake code before, but I could not understand it. It said something like that if the whole building was modeled with curtains, 1/20 of the floor height would be there, but my construction does not consist only of curtains. so do you have any more understandable advice for this? In the final version of the solution, I was able to get a report without any errors after the analysis, but I did not do the above

Mr. Levent, thank you for your answers. Problems 1 and 2 are solved, but

-Flying floors cannot be solved as a single console.

I don't understand how that is, when it comes to the ventilation gap, did you mean that the console would not be solved, or are you talking about the places in the picture below ???

The situation in the picture is meant. Please review the information given in the link below the message. If there is anything unclear, you can contact us by phone.

I also understood

-Linear floor loads are not taken into account on beams. On the beam, wall load and live load can be entered in the beam settings, additional load can be defined.

-Linear slab loads defined on hollow slab are not taken into account in the solution based on full rigid diaphragm assumption.

o How will it be to enter the wall load on the suspended floor?

A semi-rigid solution can be made or the wall load can be added to the floor covering load.

Another problem is the wall thickness issue. I had studied the article 3.6.2.1 in the earthquake code before, but I couldn't understand it. that is, do you have a more understandable recommendation for this?

In the relevant regulation article, "The thickness of the curtain end areas should be 1/15 of the floor height or 200 mm. According to this, the curtain thickness should not be less than 400/15=26,667 cm for the ground floor height of 400 cm.

In the relevant regulation article, it is stated that the thickness of the curtain end zones cannot be less than 1/15 of the storey height or 200 mm. Accordingly, for the ground floor height of 400 cm, the curtain thickness should not be less than 400/15=26,667 cm.

It is a pleasure for you to respond promptly. thank you. I already understood that event. For a curtain thickness of 25 cm, my floor height is maximum 375 cm. but I insist on having a floor height of 400cm and a curtain thickness of 25cm. Is this not possible? Is there any other way to do 25 cm curtains and 400 cm heights without increasing the curtain thickness? This is my question. I see curtains with a height of 5 m and a width of 25 cm in the application that surprises me. I wonder if they found a way or are they soaping?

 

[Levent Özpak]

... I already understood that. For 25cm curtain thickness, my floor height is maximum 375cm. But I insist that it should be 400cm floor height and 25cm curtain thickness. is that not possible? Is there any other way to do it with 25' screen and 400cm height without raising it

Error message in geometry control, It is not shown in Reports and it is not an obstacle to analysis. It's up to you whether to heed the warning or not... Good work

The error message in the geometry control is not shown in the reports and is not an obstacle to the analysis. It's your initiative whether to take the warning into account or not... Good work

Levent, thank you very much. Now how do I define this console hollow floor, how will the event of throwing beams on the edges be? I used a sta once. When laying tiles in sta, it was automatically throwing the edges here, do I enter it manually? Here, beams can be thrown on the consoles above, but what should I do with the very short 20cm consoles on the left?

...Mr. Levent, thank you very much. Now how do I define this console hollow floor slab, how will it be? Here, beams can be thrown on the consoles at the top, but what should I do with the very short 20cm consoles on the left?

The beam you say is automatically thrown is probably the constructive butt beam. You can make it continuous with D02 and D04.... 20cm console floors can be defined as slab flooring.

 

[statikçim]

or you can arrange the teeth of D15 and D05 in the lower part in the y direction and make them continuous with D02 and D04... If it becomes continuous, will there be no need for a forehead beam?

I have another question: What is the effect of this soil unit weight on the analysis results, namely the structure?

 

[Levent Özpak]

o if I do what you say, that is, if the cantilever hollow bars and the floors underneath become continuous according to the picture, will there be no need for butt beams?

You don't have to define beams because the console ribs will be continuous. Isn't it necessary to make front beams whether I throw them at the specified places or not?[/quote] Since the front beams are constructive, the drawings can be edited after taking the formwork plan.

 

[Levent Özpak]

I have another question: what is the effect of this soil unit weight on the analysis results, namely the structure?

In case of negative elevation to the foundation, the soil is applied as an additional load on the foundation (for single foundations)

I have another question: what is the effect of this soil unit volume weight on the analysis results, namely the structure?

If the foundation is given a negative level, the soil is applied as an additional load on the foundation. (For singular foundations)

Got it, thank you Mr. Levent
