Raft gives insufficient reinforcement error

[evanes07]

have a nice day; In the attached project, the raft reinforcement is insufficient. Also, 84-odd tons of reinforcement in the 2650 m2 project is not too much. What else can I do to reduce it?

Hello There are discussions and suggestions about the equipment in the forum. How do you compare the excess or scarcity of reinforcement, this is very important, there is no such measure. --Non-overlapping columns, --With the addition of raft foundation console --I increased the concrete value and fixed the right block in your project. Take it easy Unver ÖZCAN

Thanks for the information, first of all, the ground floor is planned as a car park and the other floors are planned as residences, in this way the building group is class B, right? Therefore, the raft did not fail when the superstructure was dissolved without interaction, I wonder if the non-interactive solution in this way would be correct? Also, if it's possible and it won't be a hassle, I wanted to make basement curtains under the beams in the last version of the project, but when I give the curtains -50 level, the basement beams look empty in the 3D image, is such a solution possible? Also, there were some very short things that came to my mind; 1) Is it mandatory to apply TDY 2.8.5, which is about foundations? If we don't mark this, will the project have problems in terms of approval? 2) The ratio of 1/7 for curtains is specified in the regulation, but if there are curtains smaller than 1/7 in the project, will the project have problems in terms of approval? So if we made a 25/150 screen, is it necessary to convert it to a column?

Hello

Thanks for the information, first of all, the ground floor is planned as a parking lot and the other floors are planned as residences, this way the building group is class B, right? would the non-interactive solution be correct?

The superstructure non-interactive solution is related to TDY2007 Item 2.2.1.5. The ground worker decides which of these groups are. The structure is evaluated according to this item. Accordingly, the group A soil given to you can be solved without interaction.

And if it's possible and it won't be a hassle, I wanted to make basement curtains under the beams in the last version of the project, but when I give the curtains -50 level, the basement beams look empty in the 3D image, is such a solution possible?

Such a solution is not correct , enter the very wrong curtains at the floor level, so that there are no gaps, so that the floors fit on the curtains,

Also, there were some very short things that came to my mind; 1) TDY 2.8.5, which is about foundations Is it mandatory to apply? If we don't mark this, will the project have problems in terms of approval?

It is at the initiative of the engineer, I think it is necessary to see the marked and unmarked situation and take action if necessary,

2) The ratio of 1/7 for curtains is mentioned in the regulation, but in the project If there are curtains smaller than 1/7, will the project have problems in terms of approval?I mean, if we made a 25/150 curtain, is it mandatory to convert it to a column?

There is no obligation, but sometimes the administrations can cause problems.If you make a U-shaped elevator curtain with the sides of 25/150, you have to make curtains by necessity.

Thanks for your interest; but in the description of an admin whose name I forgot in the last forum; 'if you want to define sub-beam basement curtains,' he had said; I wonder how it can be defined if I have to define it? Is it enough if I just convert the basement beams into curtains and give the curtains the height of the beams? Also; Is it mandatory to mark TDY clause 3.4.3.1 control in beam parameters? Is it obligatory to mark "Consider cantilever and simple beams in column beam shear safety" in analysis settings? In analysis settings, apply ductile materials to rigid basement ? sign of them Is it up to the initiative?

How are basement curtains defined, does anyone know?

 

[YasinTezel]

If you need to define a curtain under the beam, you must first enter the curtain settings and set the upper level so that it remains under the beam. If there is an overlap with the beam while drawing the curtain, you cannot draw the curtain. On the other hand, in the Static / Reinforced Concrete settings, the "Basement Curtain / Curtain that does not continue on all floors" option should be checked. In terms of the analysis model, the curtain and the beam will not work together. If the curtain is the whole floor length, I suggest you only draw curtains without defining beams. One more thing; Is it mandatory to mark TDY clause 3.4.3.1 control in beam parameters? It would be appropriate to do this check. Is it mandatory to mark "Consider cantilever and simple beams in column beam shear safety" in analysis settings? It is optional. Apply ductile materials to rigid basement in analysis settings ? sign of them Is it up to the initiative? It is at the discretion of the engineer.

It was explanatory, thank you.
