First of all, I apologize for not explaining the question you wanted to ask well. But of course, I am a civil engineer who can do complex calculations well. I did not read the new earthquake regulation, this information is requested in the ground reports in the new earthquake regulation, and the idecad program has updated itself. updated according to the regulation So I thought maybe there is a module in the program that gives this data directly, I took the easy way out. But you don't need to doubt my intelligence. If you noticed, I said that only the concrete weight is taken into account, I said that the reinforcement weight is not taken into account, if you take this detail into account, you can understand that I am considering a further calculation[/ quote] Actually, you explained your question correctly and clearly. The problem that ideCAD does not give the weight of the building quickly is a separate issue. You have the right to ask it to give it directly. I don't have anything to say to this. My regret is that you don't know that there is already iron in the weight of reinforced concrete. Or [i ]I think you wouldn't have said "The weight of the reinforcement is not calculated"[/i]. I say this because this is very basic information. I don't have the right to measure or evaluate your engineering competence, don't worry. I wish you a good day.
