Deformation (Sheim)

[iamahmetkaplan]

Hello everyone! I am designing a water tank, but when I design the first 3 floors of the tank, the deformation values are low, and when I go up 1 or 2 floors, the deformation values increase interestingly. For this, I took both beam dimensions and wall loads as 0, but the result was still the same! I also made changes in terms of equipment, still nothing. What can I do for the solution? Can we ignore these deformations?

If you look carefully at the first screenshot, the maximum deformation occurs at the extreme points of the inclined columns whose ends are free. Since the columns are both inclined and long in length, the 2nd order effects have naturally gained importance and their ends like cantilever beams have been displaced too much. Although there are more floors in the second image, you do not see that much displacement because the ends of the columns are connected. If the structure is to be built as in the first image, if the column ends will be left idle for visual (architectural) purposes only, you can neglect it. The interpretation of this is up to the engineer, that is to you. Good if you're a student and trying to learn building behavior. But if you are a project engineer, this question scared me.

First of all, thank you for your comment. I shared the two pictures to compare. What I want to point out is that while the deformation is normal in the first 3 floors of the design, which is in the normal construction phase, two beams give such values when input is made. Moreover, I designed the design with a column whose angle is 0 degrees! Although the deformation values are not the same, I can say exactly the same.

Add this project and the project you said you entered zero degrees. Don't think of displacements as just vertical displacements. In the dialog, mark which of the ux mange displacements you will examine. 4 defective displacement, total displacement value. The reason for the Boyle exit is the horizontal displacement contribution. There is no anomaly in the displacements you have pictured. When you add the project, we will have more information. Move the cursor to the node where you want to get the displacement, not from the colored scale on the left, and examine the displacements in this way.

If you enter the columns at zero degrees (vertical), rotation occurs at the point where the circular beams connect to the columns, which will tilt the columns inward, and this rotation causes horizontal displacement at the top end of the columns. In addition, circular beams pull the columns in axially.

If you look carefully at the first screenshot, the maximum deformation occurs at the extreme points of the inclined columns with empty ends. Since the columns are both inclined and long in length, the 2nd order effects have naturally gained importance and their ends, like cantilever beams, are subject to excessive displacement. Although there are more floors in the second image, you do not see this much displacement because the ends of the columns are connected. If the structure is to be built as in the first image, you can ignore the ends of the columns for visual (architectural) purposes only. The interpretation of this is up to the engineer, that is, you. Student It would be nice if you are a project engineer and you are trying to learn the behavior of the building.But if you are a project engineer, this question really scared me.

Sorry, I didn't see the last part, the truth is, I'm a technician, I make static designs of housing-like buildings in order to improve myself, I can't get carried away and get used to I'm trying to design. Here's how the results affect, as you can see. I'm investigating how the new forces will meet. I would also like to point out that; The reinforced concrete warehouse in the villages caught my attention with the visit of our relatives. If I am not mistaken , the warehouse was built 25 years ago , it still stands today , so what could be the reason for its standing ? Inclined columns and bow beams can cause excessive deformation. Actually, I'm looking for an answer to this question! What are your suggestions? Best regards

I redesigned the projects I took very carefully, but I can't see the reinforcement information of the beams on the last floor.

Beams do not appear in the reinforced concrete dialog and drawings because they create a closed area within themselves. select the beam and click the Object Properties command In the Beam Settings Dialog / Rebars tab, uncheck the line "Continuously accept beam at right end" and perform analysis. Good work

The beams form a closed area in themselves. does not appear in the reinforced concrete dialog and drawings for Select one of the beams, for example beam K1, and click the Object Properties command. In the Beam Settings Dialog / Rebars tab that opens, uncheck the "Continuously accept beam at right end" line and analyze. Good work

Thank you , I can see the accessories !
