Subasman curtain

[AUGURD]

Hello.. -When I make an elevator basement curtain, I need to make 140 cm in length and it does not provide 1/6 ratio, how can I find a solution? -Same pitch (P104) It does not provide shear safety and I get a lack of reinforcement error. What is the reason, although the p96 screen is the same, I can't get it on it. -I get a lot of stapling when I open the raft elevator shaft. Is the stapling reinforcement safe and recommended or how can I solve it except for the thickness of the raft. -Since I have column beam shearing problem in my K14 and K15 beams, I bend those beams from the right and left ends instead of continuously and my problem is solved, do you recommend a healthy method? -Can I define an idecadde instead of a sub-basement curtain?

Hi.. -When I make an elevator basement curtain, I need to make 140 cm length and it does not provide 1/6 ratio, how can I find a solution?

Check the " option.

It does not provide shear safety at the same pitch(P104) and I get a lack of reinforcement error. Why is it that I am getting a lack of reinforcement error even though it is the same pitch of p96, I do not get it on it.

P104 and P96 pitches are not the same. Carrier elements, their location, carrier system, etc. They get different effects for different reasons. The problem of KAS(-) shearing in the curtains is caused by the lack of cross section or the insufficiency of horizontal reinforcement (stirrup). Detailed information is given in the "TDY 2007 item 3.6.7., Equation 3.18" Shear/Screen Group Shear Safety Report. If -Ve>Vr, there is insufficient horizontal body reinforcement (stirrup). The problem can be solved by choosing larger reinforcement diameters. If -And>0.85*Ac*Fcd; limit values are exceeded. Curtain width/length can be enlarged. (Increasing the size of the curtain wall, especially the length of the curtain wall, will increase the stiffness of the curtain wall and the shear force of the curtain. It may not always be a solution.), higher strength concrete can be used, arrangements can be made in the carrier system to reduce the shear force on the curtain, etc. (New curtains can be added to the system, the dimensions of other carrier elements can be increased, etc.) You can also review the links below on this subject.

-I get too much stapling when I open a raft elevator shaft Is it safe and recommended or how can I solve it except for the raft thickness.

-To overcome the problem of stapling on the raft foundation; The thickness of the raft flooring can be increased. If the stapling problem is in the outer columns and there is no amplification, amplification can be made. Concrete class can be increased. Column/wall size can be increased. -Punching reinforcement can be used in the Curtain Properties/Punching Reinforcements tab... (The drawings of the selected stapling rebar are not made automatically. You have to do it yourself by examining the raft stapling report and using the 2D possibilities)

-I have column beam shearing problem on my K14 and K15 beams. I bend the right and left ends instead of continuously, and my problem is solved, is it a healthy method, do you recommend?

To solve the column-beam joint shear safety problem, making continuous beams discontinuous would be an erroneous approach, it is not recommended.

- Can I define a beam instead of a sub-basement curtain idecadde?

There is no such command as a beam in the program. By bond beam you mean the tie beam, the tie beam is the foundation element. Note: In the final analysis, we recommend that the curtain, floor and raft finite element widths are reduced, for example (25cm) analysis. Good work

First of all, thank you for your answer.. We are opening a critical gap in the raft, but shouldn't we define it in the program? I take 5% tolerance, it says so in the regulation. he can't throw the punching equipment himself, what should I do?

Thank you for your answer, first of all.. We are creating a critical gap in the raft, but do we need to define it in the program?

If you make a gap in its place, you should apply it. It is recommended to be applied as in the article.

I get 5% tolerance, it says so in the regulation.

Calculation and section control tolerance options in the Analysis Settings/Load security tab in the program are not a regulation item. The program has been added upon request from our users.

Can't assign the punching equipment itself, what should I do?

The punching equipment to be used Column-curtain properties/ "Punching It is selected by the user from the "Rebars" tab. Stapling control is performed automatically according to the selected punching reinforcement type and TBDY 2018. The punching equipment used in the raft punching control report information is given. Stapling reinforcement drawings are not made automatically. It is not made by the user. The representation of the punching reinforcement drawings is given in TBDY 2018 figure 7.16 in general terms. Good work
