idecad basement curtain

You cannot define it because there is no such thing as a saubasman curtain. Because there is no such definition in the regulation. the regulation is missing from this pain. however, we should be able to define curtains, albeit manually. Sometimes there is a problem in the r selection because of this issue. By reducing r from 8 to 7, we are making the system extra rigid unnecessarily.
 
The basement walls are the one with less height in terms of both their contribution to the building behavior and reinforced concrete reinforcement. Therefore, they should be defined as shell elements and included in the system. In ideCAD, you can include sub-basement walls as shell elements in your system. These walls stiffen the structure at the level they are entered and reduce the displacement. Since their heights are less than the normal storey heights, their stiffening effects become evident. They also relax the basic system. In short, it is very easy and possible to define sub-basement curtains in ideCAD. If we look at it from the point of view of earthquake regulation, the regulation did not give a different status to the basement walls than the normal curtains. In other words, let me enter these curtains, but there should not be a permit in the regulation, such as the carrier system behavior coefficient is still 8.
 
syn cassabotanic. ewt the curtains you enter in the basement are the basement curtain and the system perceives it as such, but you cannot enter it as a flood curtain. You define it as a normal shell and the ide detects it up to the rigid floor you define. however, on the floor above the fijit floor, for example, you had to add a basement screen to only one side of the building. Since the system perceives this as a curtain that continues on all floors, the program says r in a system with r 8. Never mind that single-row sub-basement curtains are included in the alpha calculation. this is wrong thing. For this reason, as far as I understand, Erman Bey asked if there was a separate way to define it under the name of sub-basman curtain. which must be in the right analysis of the system.
 
We want an explanation from authorized friends about the sub-basement curtain. If the idecadde basement curtain can be defined, can they give an example? Also, the word shell element is floating around in this idea. I confused the idea that much and couldn't find it. Can we clarify this issue? Some friends said that it also solves the ide stacking. I couldn't find it either. I've been using ide for so many years and haven't come across it yet. Best regards...
 
Hello Idecadde are the curtains placed with the panel element called shell element. Since Curtains, which are known as shell, are defined as shell element in Sap 2000, I think it is mentioned as shell element here with the same habit. Of course, the element placed with the panel command can be placed in two ways. If Define as shell is not checked in the panel element's settings, it is placed in the structure as a bar element. You see the screen as a rod in a 3d frame. If this feature is checked, it will be placed as a shell divided into finite elements and you will see this in 3d. I've been following the discussion about the basement curtain here for a while. Friends, there is no concept of flood curtain in the regulation. In practice, basement level curtains are called basement curtains. You can identify these curtains in the idea. Since it causes sudden stiffness difference in earthquake calculation, these floors can be defined as rigid floors as stipulated by the regulation. Again, in some buildings, these curtains may continue above the basement or the basement may be more than one floor. In another case, it may be called a basement and there may not be a curtain around it. The engineer will interpret which floor will be defined as a rigid floor. Trying to solve the masonry structure with the shell is not correct at this stage because masonry structures have very different controls in the regulation and idestatic does not currently do these controls because the program is written for reinforced concrete structures.

Thank you for your explanations and the information you provided. You said that you can define the sub-basement curtains at the basement level. Here is the problem. If you define a basement floor with a height of 90 cm in Idede and turn the curtain, it gives you results. But if you do the same to this floor as the columns on the ground floor, the shear force will suffer, which is normal. Is there any other way around this? In the application, the sub-basement is placed as a detail on the project sheet and the phrase ''at h'' is added. This is a perfectly normal situation. But the project you did in the idea gives me an inappropriate and incomplete quantity.
 
Mr. Erman, I think you are talking about the curtains for the purpose of raising the basement and where the foundation is placed on the ground floor without a basement. It's the basement curtains I'm talking about. I don't look at it in terms of quantity. When placing these curtains, I look at whether I am modeling the building behavior correctly. I think that it would be more accurate to place the basement curtains you mentioned by giving elevation to the column heights without playing with the floor height. Defining a separate floor for the basement curtain may lead to incorrect results in the analysis. Suat Yildirim
 
The most correct approach for the basement curtain is to model the panels as shells and enter them with elevation. Whether these panels are effective in the calculation of alpha i and determination of the r coefficient is a matter of initiative and is not specified in the earthquake code. I have given an opinion to ideYAPI that it is optional for such subbasement curtains to enter into the selection of alpha i and r coefficients. I think they will take it into account in the main update.
 
idecadde is difficult to implement in practice if you solve the problem by giving elevation to the columns without defining the basement curtain. Column confinement regions end in the sub-basement. In practice, we tighten within the sub-basement and tighten just above the sub-basement. For this reason, when you give elevation to the columns, the system does not know the sub-basement, so the tightening is normal. If you place a 1 m curtain on the ground floor, it gives the reinforcement according to the market conditions, but this time it asks you to enter the r coefficient as 7.
 
The column remaining in the sub-basement wall needs to be tightened in the other direction. Just like me, let ideYAPI know your wishes for drawing, quantity and r coefficient. What I am trying to tell you is about how to model the basement curtain in the most accurate way. IF YOU ARE MODELING MANUALLY WITH ETABS OR SAP2000, you will model as I suggest.
 
I agree, my suggestion was already the same. You can manually intervene in quantities and densifications. The important thing is that the modeling is suitable for the building behavior.
 
In my opinion, it would not be a correct solution to operate the basement curtains directly integrated with the columns. The curtains that do not continue along the floor height of 100 cm or briefly trigger the short column behavior in the system. In our projects, we normally remove the basement curtains from the system with 5 or 10 cm joints. Reporters working at IMO do not approve the projects that are attached to the column that are integrated with the system, and they recommend that they be removed from the system. Including these curtains, which are only used for filling soil or fill, in the calculations may give erroneous results. greetings
 
The fact that the basement curtains are not included in the calculation causes erroneous results. After the basement curtain, the ground floor continues at its normal level. If you do not enter the basement curtains into the system, you will enter the ground floor an extra 1 - 1.5 meters higher, or you will start the ground floor from the top of the basement. Both options are not correct models. If you build the basement walls with 5 - 10 cm joints to the columns, what you say is valid. In this case, the ground floor ceiling will make unnecessary displacement due to the extra growing ground floor ceiling level. Columns that will take extra horizontal load will be forced unnecessarily. The duly designed and built basement curtains both make the system comfortable and thus you model your building in accordance with its behavior.

I agree with what Mr. cassabotanic said.. The correct method is important, can we show the correct inundation method with a sample drawing..
 
Hello, I couldn't find any data on this subject. Any progress? I defined basement curtain at -60 level and defined it as basement curtain. This time it gives the error that the basement is not rigid? What path do you think should be followed?

Hello, there is no error message in the program that the basement floor is not rigid ... The best thing is to add your project... Let's look at your question about the data entry you want to do in your project...
