Manual intervention of additional reinforcements after analysis

[Emre.Ozcan]

It's probably a topic that has been brought up before in the forum, but I still want to ask for clear information. In my project, I get the error of insufficient reinforcement on the raft basis. As a solution, I manually intervene to reduce the additional reinforcement spacing, and when I reduce it to the required interval, the error is corrected, but when I do the analysis again, the reinforcement spacing is lower than the 10 cm I entered in the raft basic parameters, so it reduces the reinforcement interval to the lowest value, 10 cm capi does not save. It is said in the earthquake regulations that it should not be lower than 25 mm, but this figure does not seem like a low enough value to me for healthy manufacturing. I would like to get the opinion of you, my dear engineer friends. Do you think it would be more logical to lower the minimum reinforcement spacing to which value for a production that will not cause difficulties in a comfortable construction site. :?: :?:

With ideCAD, the basic additions change after each analysis, it is not locked like the main reinforcement. It is most convenient that the main reinforcement spacing is 15 cm or 20 cm on the raft foundation. If you make the additional reinforcement the same as the main reinforcement interval, there will be no problem.

This is a topic that has probably been opened on the forum before, but I still want to ask for clear information. In my project, I get an error of insufficient reinforcement on the basis of raft. but when I do the analysis again, since the rebar spacing is less than 10 cm I entered in the raft basic parameters, it again pulls the rebar spacing to 10 cm, which is the lowest value, so the reinforcement diameter does not save. It doesn't seem like a value. I want to get the opinion of you, my dear engineer friends. Do you think it would make more sense to decrease the minimum reinforcement spacing for a production that will not cause difficulties in a construction site that can be done comfortably? :?: :?:

You may not receive the missingAs message. The criterion related to the distance between ti is given in TS500, not in the earthquake regulation. Raft additional reinforcement can change the minimum reinforcement interval in the raft parameters. While giving the minimum additional range in the raft parameters, you should consider that there are also raft flat reinforcements in that region as well as additional reinforcements. For this reason, it may be more appropriate to limit the minimum reinforcement spacing to 10 cm.
