The table height is calculated according to the value given in the raft settings to the program. If the value is left zero, it is calculated as Table Reinforcement Height = Foundation Height - 2*RateConcrete Cover Thickness. If you enter a value, the value you enter is added to the height of the tripod reinforcement. A negative or positive value can be entered. If you enter a positive value, you will increase the height of the coffee table reinforcement, and if you enter a negative value, you will decrease it. Calculated as Table Reinforcement Height = Foundation Height - 2*Rat Concrete Cover Thickness + InputDIIf. The thickness of the raft concrete cover is given in the raft parameters.

You can leave the parameter I mentioned for the table zero in the raft settings.Do not set the concrete cover to zero in the raft parameters."civil63":2dmrhe2y" said:is it correct when we enter the value as zero in the parameters???
Rigid basement In a 13-floor building, in the system solved with raft foundation type, is it obligatory to have the basement floor, that is, to be rigid? (Assuming there are curtains on 4 sides) .. What kind of negative results can we encounter if a rigid basement is not built?

"civil63":3cxo0fzq" said:Is it obligatory to have a rigid basement in the system solved with raft foundation type in a 13-floor building?(Assuming there are curtains on 4 sides) ..[/quote ] The conditions for the floor to be considered rigid are given in TBDY 2018 Articles 3.3.1.1.a) and b). According to article a) for the floor to be considered rigid, basement curtains must surround the building from at least 3 sides and it is under the control of the user. Item b) the floor is rigid by the program automatically checked when accepted.
Hello My suggestions;
--There is no requirement in the TBDY2018 regulation,"civil63":q66bmtoq" said:do we have to make the basement of this 13-storey building rigid in terms of static?
-- If you build a basement building, basement curtains take some of the moments in the basement, other columns-curtains relax, but if you make the building without a basement, the sum of these moments is columns-curtains It will be more difficult for the account to recover because you have received it.

Hello
There is no such requirement in any of the 1975-1998-2007-2018 regulations."civil63":2dxyfdaf" said:tbdy 2007 did not have to build a basement, right?
