column beam shear safety

[sayın]

Hello there; In my B+5 storey project, which I have sent in the attachment, although there is no problem in the S21 column on the other floors, it gives B error on the 3rd floor. There is also the symmetry of the block in the project. There was no such problem there. I am waiting for your opinions and suggestions about the cause of the problem and its solution. .Thanks.

I encountered many problems when I had your system analyzed. Let me try to list them. 1) Since your console floors exceed the deflection limit, I increased it from 17 cm to 20 cm. I also increased the beams attached to the floor from 55 cm to 60 cm. (The thickness of the beam cannot be less than 3 times the thickness of the floor) 2) You increased the elevation of the elevator curtain on the 4th floor up to the middle of the 5th floor. This was giving an error in the curtains on the 4th and 4th floors. I reset the jeans both on the 4th floor and on the 5th floor. 3) There was always a z-stress error in your foundations. Since I thought that it would be less expensive to solve such basement structures as superstructure interactive mat raft, I converted your foundation system to 50 cm raft. When I analyzed, I saw that the s22 column gave a stapling error on the basement floor. I changed the dimensions of the s11 column to 60/30 and added a column header. The stapling error problem was fixed. By the way, the calculation axles need to be arranged in the system that was solved as matte raft. and you modeled the basement curtains as rods, not shells. I modeled them as shells. The column beam shear safety error on the 3rd floor in question has been resolved. When you look at the shear safety section of the column reinforced concrete of the s21 column, you will see that the shear safety error is caused by the k52 and k53 beams, although it does not join the column in the y direction (it joins with the P2 wall). 5) There were tile edges that were randomly drawn in your system that were not connected to any static objects, I deleted them. Before analyzing, I recommend that you take care that there is nothing in your system (normal lines, architectural borders, texts, etc.) other than static objects. Also, some of the slab gaps you created may be a problem when you receive a not fully formed mold plan. you realize) there is a shear safety error in your system in the connection of s26 column with k61 and k62 beam on the ground floor. and 169.13 tf. vmax 168.25 tf. Since the difference is very small, I didn't need to bother. (I try to do so.) Thus, production can be done more easily than the mold opener.
