Hello, I need to make a design like the one in the figure, but when the U-shaped sides are made of beams, it does not analyze because it does not connect anywhere. If I define a curtain, it accepts it as if it is supported. If U-shaped beams are thrown, does it become a polygon beam like a polygon column, I looked at it but there is no, how is this design healthy can we model
 
Re: Reinforced Concrete U slab definition Hello; You can create this type of model with the help of freestanding curtains and flooring instead of beams. Sample model file is attached. Best regards.
 
Re: Reinforced Concrete U slab definition First of all, thank you for your answer, I modeled as you said, but I still get an error and it is not resolved. Could you please have a look at my model? where am i doing wrong?
 
Re: Reinforced Concrete U slab definition Hello; You should not draw tile edges on the edges you draw curtains, the error is due to this. Curtains will already serve as border elements for floors. Also, since there is no curtain in your project, you cannot analyze if you choose a cork flooring system from the TBDY2018 wizard. The choice of cork flooring system is required for two-stage analysis in building type structures. In your project, it will be sufficient to solve semi-rigid and consider in-plane effects. The corrected model is attached. Best regards.

Yes, I am using V10.13. V8.62 version of the file is attached.
 
Re: Reinforced Concrete U slab definition thank you for sending it, the coating load on the floor with zero elevation is 1.5t/m^2 live load 0.15t/m^2 width 190cm. Is this coating load for landscaping? For pedestrians, isn't the live load too small? floor covering load at 100cm elevation 0.532t/m^2 live load 0.15t/m^2 width 340cm if pedestrian crossing the live load is very low The structure, which is considered as a beam, does not continue at its height. If there are special cases, can you make the necessary explanations?

The floor covering load with 100cm level is 0.532t/m^2 live load 0.15t/m^2 width 340cm if pedestrian is passing, the live load is very low, why is the purpose of use of the building + loads? it was chosen this way + 4/5R should be applied or not, if possible, can you explain together the reason why the curtains are not supported, they do not continue with the height of the structure, like beams. If there are special cases, can you make the necessary explanations

I think you are asking these questions to Mr. ermancnl, the project he's the owner, i just clarified his problems in modeling
 
Re: Reinforced Concrete U slab definition sec. Let's find a question to ask 2m project :?: When I look at the reports, it says apply 4/5 R 4.3.2.4 In case one of the two defined conditions (a) and (b) cannot be met, 4/5R can be used. He says 4/5R should be applied, if possible, can you explain together with the reason, there is no situation related to the base overturning moments of the curtains, the walls are unsupported, they do not continue at the height of the building, which is considered as a beam. If there are special cases, can you make the necessary explanations, if there is no need to apply 4/5R, or the warning printed in the report should be taken, Will they share their opinions with other friends who will be removed?

Hello; First of all, in order to create the desired model, the shears/shell elements defined as unsupported (connected/supported to floors modeled as shells rather than to the foundation) are defined in the earthquake code to create the desired model. It is not considered and cannot be considered as a carrier earthquake shear used to meet earthquake effects. It is a vertical shell element that meets the effects in the model. After giving this information, the answer to your first question is given automatically. In TBDY2018, in cases where 1/3 and 1/6 controls of carrier earthquake curtains are not provided It says 4/5R reduction should be done, in our model Since the curtains are not bearing earthquake curtains, there is no need to apply this article. Best regards.
 
Re: Reinforced Concrete U slab definition If you look at the scope of TBDY; The provisions of this Regulation are applied for the design of new buildings to be constructed under the influence of earthquakes, evaluation of existing buildings and retrofitting design. The provisions of this Regulation are applied for the design of buildings made of cast-in-situ and pre-engineered reinforced concrete, steel, light steel, masonry and wood materials under the influence of earthquakes. Structures other than buildings and building-type structures such as bridges, dams, coastal and port structures, tunnels, pipelines, energy transmission lines, nuclear facilities, natural gas storage facilities, structures that are completely underground and other structures that are designed according to calculation and security principles different from the buildings. structures are outside the scope of this Regulation. Until their own special regulations are made for the design of buildings and building-type structures outside the scope of this Regulation under the influence of earthquake, first of all, together with the provisions given in the relevant Turkish Standards, technical regulations such as other internationally accepted equivalent standards, regulations or technical rules determined by their institutions, the technical rules stipulated in this Regulation It can be used by considering the principles. You cannot design this type of structure using only TDBY. I suggest you look at AASHTO for the R coefficient and other specific provisions you should use.
 
Re: Reinforced concrete U slab definition how to remove the 4/5R warning printed in the report, the problem is because it is printed in the report, so that the above warning is not printed in the report, the statement of 4.3.2.4 (a) and (b) checking if there is a supportless curtain in the structure is applied to the algorithm. should it be added
 
Re: Reinforced Concrete U slab definition Hello; First of all, we should listen to what Mr. Miralay said, this building is not a building type and we do not know what it will be used for. It is necessary to work according to the appropriate design rules. Coming to your question, 1- By selecting your unsupported curtains and entering their properties, it is necessary to say that the flood / curtain that does not continue on all floors, the controls requested for the earthquake curtains in the reports should not be made for these curtains. Thus, you will not receive a warning that 4/5R should be applied. 2- You can determine whether or not the 4/5R item will be applied from the analysis settings menu. Also 4.3.2.4. Whether or not the article will be applied is presented to you as an option. Best regards.
