System Unable to Solve Error...

Good work.. Similar ones have appeared on the forum before. I looked at the suggestions in that topic, but I couldn't find a solution. As far as I understand, there is a problem with modal analysis. I've been dealing with the same problem for two days with my project, but I couldn't find a solution. Can you help me.
 
For one beam, it gives a warning that "the beam may have been adjusted with an incorrect angle". but in another project with a similar system, although it gave the same warning, I did not pay attention to that warning because the system broke and I got the results. Or do I have to care? ???
 
1st floor level, in the upper left corner, a small piece of beam remained at the junction of the K1 beam (probably as a result of automatic splitting during the definition of cantilever floors). If you delete the beam piece, there is no problem.
 
In my project, the system gave an error that it could not be solved, when I said solve the foundation and the superstructure interactively...plus in the same project, although KM and RM are very close to each other on the ground floor, the report says that they are much larger than 1.20, but KM and RM on the top floor are very separate from each other, but 1, It gives a value close to 20...even in a 6*6 slab, the reinforcement is insufficient, 15 cm slab and c25 concrete..everything is normal, but I couldn't understand why these slab lines are divided with A1. I would appreciate it if you help me :((....system I will send it but it says the file size is too big.. I don't receive it :(
 
I am attaching the project.. According to me there are many curtains, but still A1 does not provide torsional irregularity why :(..I would appreciate your help

Hello, -In the project you added to the forum, the superstructure can also be analyzed interactively. There is no problem. There is no problem with the lack of reinforcement on the floors. I couldn't see a warning -The closeness of the center of mass and stiffness does not mean that there will be no irregularities of type A. According to the regulation, the calculation of the relative storey drifts is made by taking into account the 5% additional eccentricity effects. (The nbi values in the project are also large. not load values. The largest nbi value is 1.26.) Also, the A1 type irregularity is an irregularity that affects the selection of the calculation method. This irregularity is of no importance when dynamic analysis is performed. Regulation Article 2.3.2.1 Notes: 1- It is appropriate to define arc-shaped beams with arc beam command instead of curvilinear beams so that floor and 1st floor slab analysis can be performed on the entire slab at once. 2-When defining a continuous basis under the panel object, it is appropriate to connect it from one node to the other node of the panel. Good work
 
When I sent it, there was a warning that the floor does not save, the reinforcement is insufficient... Thank you for your information, Mr. Levent.. Did you make any changes on the project, so instead of the curved beam you mentioned, it was like clicking on the start and end point of the panels after the arc...???... Aren't there many curtains in the system?

I'm already doing that optimization... the system is broken now, but I'm trying to improve it further... if you have something to add, I welcome your suggestions.. thanks for everything in advance..
 
I'm crazy I installed the system (it's not very good, but it still needs to solve it, at least it should show the errors. It doesn't do it either. The system can't be resolved. I need an urgent answer. I wonder what can I do. I thought I should upload the file. I zip it 26 mb. It's 3 mb, but I can't upload more than 2. .what can I do.
 
I'm trying to solve a 5 floor area, the ground analyzes up to +3 land, the system cannot be solved when you add the 4th floor, it says check the geometry, I do it says everything is OK, I'm crazy [email protected] my e-mail address is here can we communicate
 
The system cannot be resolved warning usually appears due to zero-height elements or situations such as elements that are not connected at both ends (left in the air). In this case, the program will tell you the node number and coordinates that it has problems with while downloading the matrix. In your project, the warning message appears as "X : -1.25 Y : 8.43 Z : 9.40". If you examine the coordinate given in your project, you will see that when connecting the K5 beam to the vertical beam, a zero-length part remains due to automatic division. If you select and delete these parts (All normal floors have the same situation) your project will be solved. The corrected version of your project is attached.
 
SN ftoprak58 I LOOKED AT YOUR PROJECT: BECAUSE THERE IS NO RIGID CURTAINS IN YOUR BASEMENT FLOOR, YOU NEED TO GIVE THE "UPPER RIGID FLOOR NUMBER" -2 as -1. GOOD LUCK WITH.

Hello, "The system cannot be resolved" warning is caused by the zero-length element at the intersection of the K19-K05-K23 beams on normal floors. If the eccentricity of the K19 beam is defined as 0.1 cm from the top, the problem is solved. Other project determinations and suggestions **A small beam piece formed at the intersection of P05 and K209 on floors 2 and 4. **As there is no perimeter curtain on the 1st floor, the upper rigid basement floor number should be -2 in the Analysis Settings/Tdy Options Tab. **On the 4th floor Linear slab load defined on beam K413. With linear load command, only the load must be entered for slab slabs. You must define the load on the beam from the building tree. You can watch the following training video about the subject.

**Continuous foundations entered under the panel object are incorrect. The continuous basis should be defined by clicking the start and end nodes of the panel. In addition, the foundations under the columns on the A and C axis do not seem to be connected to the columns. You can view the sample project. Good work
