Is the base system data entry correct?

Hello friends, take it easy, I was going to have a question about the project I added in the appendix. I want to create the basement floor only within the boundaries determined in the draft. The left side will remain empty, can you help me how to arrange it statically.

Hello, The program you created is definitely wrong in terms of data entry for the foundation system version 7. In this way, the effect of the columns sitting on the raft slab is not taken into account in the foundation design. On the raft-free raft foundation, the raft slab borders should be formed with the slab edge, continuous foundation should not be used. In the rafter raft foundation system, all columns and curtains should be connected to each other with continuous foundations, raft slabs should be placed in the cells formed in between.In addition, the superstructure interactive solution is foreseen in the beamless raft foundation system in the program.If the floor group is C or D, the foundation system is designed as a beamless raft in terms of program and regulation compliance. superstructure interactive solution zooming is appropriate. Good work
 
Re: basic Thank you for your answer Mr. Levent, when you applied the changes you mentioned, the system came to life this time. I designed it as a raft without beams, but when you define the basement curtains, it shows an error again. Can you help with the project, thank you again..

If you add your project that you designed as a beamless raft, we can check data entry.
 
Re: foundation Mr. Levent, I have created the foundation without any problems, thanks to the information you have given before, thank you. I am currently encountering the message of high relative floor drift on another project. Also, my s12 column in the corner is struggling despite my cross-sectional enlargement. Can you help me? thank you..

Hello, I couldn't see any problem with data entry and analysis model in your project. The structural system seems weak in the x direction. It is relative that you should increase the stiffness of the carrier element especially in the 5 and 6 axes in the X direction. It helps you to solve the offset problem.For the solution of the join break safety(B) problem, you can check item 9 in the link below.

Re: Temel Hello Mr. Levent, I had a question, can you help me? I designed my project as rafter raft. There is no problem in my analysis, but the stirrups that are constantly thrown transversely in the foundation tab are very frequent. In the projects I've done before, even if it was always shown as a single stirrup in the foundation tab, it was showing as double stirrups in the drawing. Currently, this is not the case, unfortunately, when I received the drawings, they were all single It seems to be from stirrups. I will be very pleased if you share your information on the subject. I wish you a good day and good work..

Unfortunately, when I get the drawings, they all appear as single stirrups. I would be very pleased if you share your information on the subject. I wish you a good day and good work.. [/ quote] Hi, Continuous basic widths are entered as 50 cm If the "minB for double stirrup" value is entered as 50 cm instead of 65 cm in the Continuous Basic parameters, double stirrups are thrown.
 
Re: Temel Thank you Mr. Levent, I made the adjustments you mentioned and it threw as double stirrups. But it throws the stirrups on the beam very often. That is, it throws the stirrup along the beam in a certain cm range. It does not tighten on the support edges. I wonder what is the reason for this.

Levent, thank you, I made the adjustments you mentioned and it threw as a double stirrup. But it throws the stirrups on the beam very frequently. When I remove the option of tightening stirrups from the continuous basic parameters, this time it does not tighten on the support edges. I wonder what is the reason for this.
Larger diameter stirrups can be used to increase the spacing of the stirrups. The foundation height can be increased. etc.... Since you removed it, there is no tightening at the column edges.
 
Re: Temel This is not possible Mr. Levent. :| It doesn't change anything when I increase my base height, on the contrary, when I decrease it, the situation turns in my favor, but I want to keep my height at one meter. I don't want to decrease it. Even if I change the thickness of the stirrup, it gives frequent reinforcement.
 
Re: foundation I guess that the project is a simple residential structure. Therefore, I recommend you to check your loads, especially floor loads. You have taken both live loads (0.300, it could be 0.200) and fixed loads (+0.350) in flooring, which I think is a lot. In addition, some floors have additional walls. In addition, it is seen that the thickness of the very small floors is 12 cm. This means extra heavy load. Similarly, check the beam loads. For example, although your floor height is 300, the wall information is 268 high. Evaluate the floor and wall loads in the attic separately. Other than that, I don't find it right to use stirrups with 8 reinforcements on a 100 cm continuous basis. Because the winding reinforcement length will be approximately 500 cm for 90+90+40+40+hooks. For this already thin reinforcement diameter, such a stirrup would not be suitable for its purpose. There is a lot of deformation. You can make the foundation beams wider. I don't know why you are in a situation to make 100 cm. In my opinion, I would solve this system as a raft without beams. If I had to raise it, I would use 50-60cm whatever floodgates. I wouldn't bother to include them in the system. I would take care not to create short columns and recommend the installation within this framework. I think this would be a more economical and good solution. So far I have written about your problem. Other than these; your frame formation is not healthy at all. There are quite a few and inconsistent stud beams. Especially the connections of columns S1, 2, 3 are very inadequate. Moreover, you have connected a cantilever beam from the column to the S1 column. The beams you put at the end of these columns, which are not connected in the X direction, are also 25/32. If the slabs in your building are ribbed slabs (which is evident from the slab thicknesses), then don't you need to connect the columns as well? You need to change the direction of either beam K18 or K19. You will see the problem when you get the beam details. A console from a column and a console from a beam is definitely a situation we do not recommend. (Like normal floor K5 4th floor K41, K43 beams). Almost all of the columns are lined up in the Y direction, since they will all be in the Y direction (which you should not do), at least make the narrow sides 30 cm. You did not include the stair loads in the building that you loaded so much. I also suggest you to solve the structure as superstructure interactive and semi-rigid diaphragm. I have written in detail so that other friends do not make similar mistakes while writing to you. Take it easy. Good work. Note : The engineer does not have to solve every project. Does it solve? Solves it! But both architects and clients must suffer the consequences. Therefore, the solution authorities are these three partners. If the system compels you and does not suit your mind and engineering, send it to its architect to work a little more. Let him find some solution so that he does not have to send projects of the same style to you.

Hello Mr. Emrah, In your project, the minimum B value for double stirrups is set as 50 cm in the Continuous basic parameters dialog, and in the Rebar selection dialog. If the stirrup reinforcement is 10, the spacing of all stirrups is 10 cm except for two continuous foundations.Since the foundation spans are short, there is not enough distance for the middle zone stirrup when tightening by 2h from both ends Other Notes: -Short cantilever defined in columns S02 and S03 foundations cause mat flooring to form incorrectly S02-S05 and S14-S11 columns are connected with continuous foundations it can cry. Continuous foundations can be defined between the columns S04-S05, S07-S08, S10-S11. -Also, from the Optional Report dialog, it is clear that the Ground group is C. As I mentioned above, in terms of compliance with the Regulation and the Earthquake Code, it would be appropriate to design the foundation system as a beamless raft and make an interactive solution with superstructure. Good work
 
Mr. Yılmaz, levent, thank you very much for the information you have provided. You took your time and took care of it. I didn't want to include cm in the flooring. Thank you, I wish you a good day and good work..
