Urgent comment about my project

[xalox]

S7 - S8 - S9 - S12 and S13 columns on the ground floor how to reduce the pursantan. How can a weak column error be fixed? It is very troublesome for the architect to solve it by increasing the column sizes. Thank you in advance for your help and comments.

Mr. xalox Is this project a new project you have done?

sn unver no I had added the same project in the forum before. I edited it again taking into account the warnings. I analyzed. this time, excessive reinforcement appears on the columns around the stairwell, on the ground floor columns. I also want to use beams 30 x 60. I added curtains to the system. I made the curtain thickness 30 so that the beams fit on the curtain. Architectural hinders the length, which should be 7 times longer. These are the problems. I look forward to your experience, thank you

Mr. xalox I looked at your previous project, and my suggestions are: 1- You can get the upper rigid floor number as -1 because you added curtains to the basement floor. When this value changes, your column reinforcements decrease a little. In my opinion, if you increase the columns with more reinforcement by 5 cm, you will reduce the reinforcement even more. 2-make the beams 30/60 as before 3- if you can put a curtain in the weak direction of the building. It further reduces the column reinforcements. 4- Solve the building with a semi-rigid diaphragm. Unver ÖZCAN

sn unver first of all, thank you very much for your help. I reorganized my project considering what you said in the 2nd post and the first post. I added the ladder and solved the project as a semi-rigid diaphragm. The final version of the project is in the link.

a few questions that I would like to ask you. What is the difference between the install? When we want to solve the ladder with the structure, there is a direction that it will be correct to solve it with the 2nd option. My second question is that the reinforced concrete column tab has sg pursantaj (- ) negative values. what does this mean. In the third question, I defined the curtain columns, some of them as panels, and some of them by entering 25/175 size in the column. Are they both the same thing? Or is there a difference? 4. I entered the dimensions as 30 x 36 so that the beams do not sag in the room upon the request of the customer in the closed exits. I would like to thank you again for taking the time to answer my questions, master. I wish you all the best

1. What is the difference between the mode coupling method and the diaphragm eccentric moment loading in the analysis settings.

In the mode coupling method, the floor forces are combined modally with the CQC method. earthquake effect integration is done

2. my question is there are minus values of reinforced concrete column tab sg pursanaj (-). what does it mean.

SGPursantaj: It is the ratio of the reinforcement amount calculated from the design influences to the column area as a percentage. A negative value or a positive value below the minimum pursantage indicates that the column cross-section is not stressed.

Question 3, I defined curtain columns, some as panels, and some by entering 25/175 size in the column. Are they both the same thing or is there a difference

If curtains are entered as a panel object, I defined them as a shell Note: In the project, although the upper and lower edges of the ladder are free, they are marked as fixed support.
