How can I deal with insufficient reinforcement on raft without beams?

What can I do for a beamless raft basically a REINFORCEMENT INSUFFICIENT warning? Increasing the thickness was not enough...
 
Re: Insufficient reinforcement Hello, In terms of reinforcement areas, the program needs larger reinforcements. Increase the rebar diameters that can be used for beamless rafts in rebar selection.
 
Re: insufficient reinforcement Hello Mr. Hakan, My Radye basic equipment is normally ø18. After your message, I went up to ø24 just in case... Still it didn't work. Is there another way?

Missing As messages come out according to the diameter and reinforcement spacing criteria to be selected. See for which region the Missing As message is given and examine the moment of that region. Most likely, the moment is high and because the program cannot go below a certain range and also cannot increase the diameter, it is giving the message...
 
Re: insufficient reinforcement Yes, there is too much moment on a column. It didn't help me to reduce the load on it. I can't make any changes regarding the location of the column or the shape of the building. Do you have any advice?
 
Re: the reinforcement is insufficient hello, first I made a complete analysis, as you said, the reinforcement in the raft foundation is insufficient, it is also the raft laying made of reinforced concrete, and then I go to the additional reinforcement tab and reduce the spacing of the missing red-lit reinforcements to 4-5 cm. . In such problems, it is better to look at the overall raft after providing sufficient space for the additional reinforcements. that is your problem. What I don't understand is that you made the outer curtains that should be on the 2nd floor in the 1st basement, was it overlooked?
 
Re: insufficient reinforcement Hello, reinforcement intervals have been reduced as you said. But for some reason, when I load the project you sent, it still gives the same error. Thank you anyway. While I was sending the curtains, I sent it invisibly ;)
 
Re: insufficient reinforcement hello, I also get the error of insufficient reinforcement in the raft slab. When I enter the raft slab from the reinforced concrete tab, I reduce the additional reinforcements by 5 cm. It seems to save firstly, but when I analyze again, the reinforcement intervals that I changed are restored. I would be glad if you are... good work...

hi, but when I get the analysis again, the reinforcement ranges I changed are back to their old ways. I would appreciate your help... good work...

Since there is no possibility to fix the reinforcement for the raft slab additional reinforcement tab, it is normal for the rebars to become the first after the analysis. It seems to save[/quote] You can allow the program to select higher reinforcement for raft slab additional reinforcements in the reinforcement selection, or you can reduce the minimum reinforcement spacing value in the raft slab parameters or increase the raft slab thickness. Good work..

It is normal for the reinforcements to return to their original state after the analysis, as there is no possibility of fixing the reinforcement for the tab for raft flooring additional reinforcements.

In the reinforcement selection, the program selects higher reinforcement for the raft slab additional reinforcements. You can allow it or you can decrease the minimum reinforcement spacing in the raft slab parameters or increase the mat slab thickness. Good work..

Good day, Hakan: I also have insufficient reinforcement in the beamless raft and I need not use more than 16 gauge iron. I add the pile to the required reinforcement area at the top. I provide it, but there is no change at the bottom. I add an addition to the bottom, but there is no change in the reinforcement ratio, so it does not see the addition.

Good afternoon, Mr. Hakan: I also have insufficient reinforcement on a beamless raft and I need not use more than 16 gauge iron. I add a pile, I provide the necessary reinforcement space at the top, but at the bottom No change. You can check the links below regarding the lack of reinforcement

Hi, Tensile stresses may occur in both the upper and lower parts of the raft at different points. Therefore, it would be appropriate to choose the reinforcement type as top + flat reinforcement at the bottom. You can review the links below regarding the lack of equipment:

Good work[/quote ] thanks for your answer. When I checked, the moment is too much at the bottom, do I not have a chance to solve the reinforcement problem by adding it to the bottom?

If you enter additional reinforcements in the Tiles tab, these lines have no function. Rebar diameters and spacings in the Additional Rebars tab should be intervened.

Mr. Levent, thank you for your answers. I have a question there will be more. I want to put a support tape on the raft foundation, but there is no right now, maybe then the reinforcement problem will disappear if I can.

What do you mean by the support tape?
