Hello, I cannot add the reinforced concrete calculation axes of the stairs specified in the building in the project that I have sent in the appendix and define the support conditions depending on the beams. Also, the steps of the ladder were laid straight, not in accordance with the turning diameters. Due to the problems I have mentioned, I cannot solve my project properly. I would appreciate it if you could help me with the solution of the ladder I sent. In the project, was it made in accordance with the laying method on the left side of the stairs as a console on the 1st floor. (When I define the slab as console slab from both axes, I get an insufficient As warning) Please report any errors, mistakes and comments on the attached project you see in my project. This will help me a lot to move myself forward. Thank you so much in advance.
 
Mr. MustafaUcoz I looked at your project, the ones that caught my eye. 1- SA2, SK4, SK5, SH8 columns should be extended to the top of the foundation, 2- the support condition of your ladder should be corrected, 3- when the support is corrected, the ground floor D006 slab is saved by 15 cm (because one side of the ladder and the floor edge are supported) 4- this The thickness of your ladder is 15 cm. You'd better increase it. Q30 iron is seen when the straight axle is passed. 5- The tie beam BK6 25/50 is visible on the foundation on which the ladder is supported. As far as I know, it does not solve the problem when the ladder is supported on the tie beam. enlarge for him. 6- You made a broken tie beam on the BK3 end. better give it in a straight line joining from column to column. 7- The SG2 column resting on the beam carries a load of approximately 3.5 tons. the beam it sits on is without a table. According to the 2007 earthquake code 2.3.2.4 (b) , "all internal force values formed by the joint effect of vertical loads and earthquake will be increased by 50%." Make sure that the reinforcement is placed according to the article . The building inspects. 8- There is no error in the data entry in the geometry control, but in the drawing of ground floor K016 25/70 beam, the reinforcements do not go up to the column ends. The drawing needs to be corrected. 9- It would be better if the ST10 basis given in the geometry control is corrected. 10-NO SF6 BASIS. I wanted to put a check for raft foundations before. As you can see, it is forgotten to lay the foundation under the columns. It would be good to check whether all the columns are under the foundations or not. 11-better solve your system as semi-rigid diaphragm. 12- RECOMMENDATION: If possible, do not press columns on the beam. Even at the cost of changing the architectural project. (Convincing the architect.) Attached is your corrected project. (There is still a problem on your staircase.)
 
Thanks for your response. I just can't open the cde file you sent. I corrected the items you wrote in your answer one by one. In the project, I had to press the column on the beam persistently. I will check the article in the earthquake code. I haven't been able to find the solution for the ladder since the time I wrote the title. I could not open the corrected file you sent. Thanks a lot for your help, you've been very helpful.
 
When I try to open the file, an error pops up saying it could not find the location of the file. Do you know what the reason for this is? I got the same error from the rar file you sent. Could it be a solution for me to write the folder names where your Aceba idecad file is installed and upload the file I downloaded there? thanks for your interest

Hi, I cannot add the reinforced concrete calculation axes of the ladder specified in the building in the attached project and define the support conditions depending on the beams. Also, the steps of the ladder were laid straight, not in accordance with the turning diameters. Because of the problems I mentioned. I cannot analyze my project properly. I would appreciate it if you could help me with the solution of the staircase I sent. Was it done in accordance with the flooring method on the left side of the staircase as Console on the 1st Floor in the project. (When I define the flooring as console flooring from both axes, I get an insufficient Ace warning) Please let me know about any errors, mistakes and comments about the attached project. This will help me to move myself further. Thank you very much in advance.

Hello, -In the program, the reinforcement drawings of straight-armed stairs are made automatically. Therefore, suitable for the geometric shape of your staircase, Reinforcement axis drawing is not possible. -In order to support the upper edge of the staircase to the beam, the Solution with Structure option must be selected. It should be arranged as a fixed support as it does not fit on the lower edge of the ladder or on the foundation beam. In addition, it is appropriate to perform analysis with the semi-rigid diaphragm option in the Analysis Settings. - The 2nd account axis of the D07 floor worked as a console. Since this slab sits on the columns in the K axis, it would be more appropriate to operate the reinforcement calculation axes as top+bottom flat reinforcement with the Reinforced Concrete calculation axis edit command. -I am not writing again because Mr. Ünver stated the problems related to the foundation. Good work
 
Levent and Ünver, thank you very much for your help. -Only I still cannot open the attached files with the extension cde and ide7. "location of file" ide7. Not found. I am getting a warning message. I wish you good work.

Contact us by voice. Let's examine the problem by providing remote access to your computer. Tel: 0-224-2206717 Additional information: In the project you added to the message, a positive elevation is given to the beam K016 on the ground floor. If the beam is given a positive level, it is appropriate to give an upper level to the columns to which the beam is connected In case the same columns continue on an upper floor, the relevant columns should be shortened by raising them to ensure vertical continuity.In addition, to prevent crossing of the K016 and K017 beam reinforcements, the beams must be selected in order, and in the Reinforcements tab in the object settings, the line of the K016 beam -Bend the reinforcements at the right end-, K017 It would be appropriate to uncheck the -Collapse the rebars at the left end- lines of the beam.

can we assign calculation axes to the following ladder.

Hello In the program, reinforcement drawings of straight-armed stairs are made automatically. Since the staircase in your project is a circular staircase, you can analyze the reinforcement drawings by defining the reinforced concrete calculation axes, but you can analyze the reinforcement drawings in 2D drawings. You need to edit it using the tools. You can benefit from the automatically prepared section / view and staircase drawings while making the drawing arrangements. Since the formwork plan and the bearing elements of the stairs are not clear in your project, I set the support conditions as a solution independent of the structure and drew the reinforced concrete calculation axes of the stairs. (Draw reinforced concrete calculation axis for the staircase in the Ladder Toolbar. and Determine stair support conditions) Attached project Stair drawing and 1 automatic section taken You can edit reinforcement drawings using 2D drawing tools.
 
Thank you Mr. Yasin, I wrote to the forum to see if it was possible to cast a spring-shaped account axle. I'm doing it as you sent as an example, thanks
