Upper Rigid basement floor number

[M.atalay]

Good luck to everyone, Mrb. The program automatically always includes the value -1. There is a basement in the building, but it is not embedded in the ground, it is not a rigid basement. In this case, shouldn't we write 0 instead of that value? I couldn't understand the logic of this, I'm waiting for your help on this issue, thank you.

The program always automatically includes a value of -1. There is a basement in the building, but it is not buried in the ground, it is not a rigid basement. In this case, do we not need to write 0 instead of that value?

It changes according to the number of the floor corresponding to the rigid floor. As the rigid floor number, the floor number in the Floor General Settings dialog is important. The floor number is written as the upper rigid floor number in the project general settings. The floor with the rigid floor number and all floors below that floor are considered rigid basements. If there is a floor without a rigid basement in your project, the number of a non-rigid floor is given as the rigid floor number.According to the example, if your ground floor is defined as floor zero in the floor general settings and there will be no rigid basement on the ground floor, the upper rigid basement floor number is given as -1. (non-floor number) Another example, if your ground floor is defined as floor zero in the floor general settings and rigid basement is defined on the ground floor, the upper rigid basement floor number is 0. Another example sample; For example, if your 1st and 2nd basement floors are defined as -1 and -2 floors in the floor general settings, and if rigid basement is defined for those floors, the upper rigid basement floor number is -1. (Floors -1 and -2 become rigid basements)

Mrb friends, take it easy everyone.. I have a question, for example, in a double basement building What should I write instead of the upper rigid basement floor number . There is a basement in the building, but it is not buried in the ground, it is not a rigid basement. In this case, do not we need to write 0 instead of that value? Each floor is given a number in the ]-N-[/b] column -Upper rigid basement floor number-The floor number entered in the line determines from which floor a rigid basement will be taken. and -1 should be written in the -upper rigid basement floor number- line since -1 is written in front of the 1st Basement Floor in the Floor General Settings Dialog. It means that the floors numbered -1 and below are considered as rigid If -zero- is written here Si Since the number fr(0) is in front of the ground floor, it means that the ground floor and the floors below are considered rigid. In addition, information on the number of rigid floors received in the project is given in the Building General Information Report. Here you can check the accuracy of the rigid floor number you entered.

Thank you, I understand now, but I think you mistyped it unconsciously when you said it last time.. When we give the upper rigid basement floor number -1, isn't it only the 2nd basement, not the 1st basement, that becomes a rigid basement? . Because according to what you said, you said that when we give -1, it means that there is stiffness in the points below -1. So if we want to show 2 basements under the ground as rigid, we need to write 0 again, is it true according to what you said?

Levent Özpak Thank you, the situation is resolved now, thanks. Have a good work.

My project, which is Z+2 floors, is surrounded by a basement screen of only 1m. So should I get the upper rigid basement floor number -1? Friends, I am a new user of the program, I would appreciate if you could help me, thanks.

My project with Z+2 floors is surrounded by only a 1m basement screen. Therefore, should I take the upper rigid basement floor number as -1? Friends, I am a new user of the program, I would appreciate if you could help, thanks...

According to the information you have given, the upper rigid basement floor number should be entered -1 You can find information on how to enter the rigid floor number from the link below.

Mr. Hakan ; As far as I understand, in the example given by our friend, there are 2 basements under the ground and it is called -1,-2. and it is said that no floor is buried, that is, it is not rigid... what I understood from previous articles and some studies... here the friend will write -3 in the rigid basement floor number section (non-floor number)...is it correct?

 

[HakanŞahin]

as far as I understand, in the example given by our friend, there are 2 basements under the floor and it is referred to as -1, -2. here the friend will write -3 in the rigid basement floor number section (non-floor number)...is it correct.?

Yes, if there is no rigid basement, the non-existent floor number -3 will be entered ...

Yes, if there is no rigid basement, the non-floor floor number -3 will be entered ...

thank you... by the way, I got my program as 6.54 version. your work is very good. I wish you continued success... you are super...

Correct me if I'm wrong, because as a new engineer, it is not my place to judge, but in many messages written here, it seems as if some friends think that the basement becomes a rigid basement floor by burying it in the ground. As far as I know, in order for any floor to be considered as a rigid story, the floor stiffness must reach a certain level (rigidity to withstand the earthquake load when solved with R=1.5) so that the earthquake force distribution can start over this floor. Or is it not necessary to think that when burying a solid that has not reached sufficient rigidity in the ground, in the event of an earthquake (and sometimes the soil water pressure can do its job without the need for an earthquake), under the influence of lateral soil loads, those columns can break with a "click"? Moreover, since the V7 has not arrived, I think that most people probably do not have soil load on the floors that are buried in the ground and the curtains are not turned. So what I mean is that the concept of being rigid should be established, not buried. Respects.

if there is 1 basement floor in the building (this is the case in old buildings) and if it is not rigid, then we will enter -2 then... take it easy, have a good work...

Floor General If -1 is written in front of the 1st basement floor in the settings dialog and the 1st basement floor is not rigid, then the upper rigid basement floor number should be written as -2. Good work.

Mrb friends, take it easy everyone.. I have a question, for example, what should I write instead of the upper rigid basement floor number in a double basement building. The program always automatically takes the value -1. The building has a basement but it's not embedded in the ground, it's not a rigid basement. In this case, don't we need to write 0 instead of that value? I haven't been able to figure out the logic of this, thank you.

Flash flash flash... " NO TO THE UPPER RIGID BODRUM FLOOR CONFLICT" I say the most practical form in the upper rigid basement floor number: " Come from top to bottom, the first rigid floor you encounter[/u ] is the upper rigid basement floor number. If there is no rigid floor, the number of the floor that does not have in your project is." I hope this can be easily understood in the attached two pictures. As seen in the pictures, you will understand it more easily when you follow the arrows.

My friend NYILMAZ, you couldn't explain it better than that, young friends now understand.

Thank you for being very descriptive.

hakan bey; as far as I understand, in the example given by our friend, there are 2 basements under the floor and it is referred to as -1,-2. and it is said that no floor is buried, that is, it is not rigid... from previous articles and some studies I understand... here the friend will write -3 in the rigid basement floor number section (non-floor number)...is it correct?

Hello, my friend NYILMAZ explained it very well with visuals. Let me say a few words. The definition of rigid floor is earthquake It is a data based on the calculation of the loads. It is not directly related to the fact that a floor is below the ground level. The general approach is that if the horizontal forces on the floor are only carried by the shears, this floor is a rigid floor. Since the 4 sides of an underground floor are surrounded by curtains, the floors under the ground are natural Well, can we consider a floor that is surrounded by curtains on 3 sides as a rigid basement floor? There are no curtains on all facades on the floor. The current 2007 earthquake code unfortunately does not explain such situations. In such a case, what we need to do as engineers is to control the distribution of the floor shear force on the basis of element by making a fictitious loading. If the curtains carry 90% or more of the floor shear force, I believe that the rigid floor is acceptable. Fortunately, the new regulation, which is planned to come into force at the end of 2016, clarifies this issue and determines whether that floor is a rigid floor by comparing the periods. Love, good work.
