The Problem of Insufficient Lovers

Hello, No matter how often I throw the lovers in the project I am doing, no matter what section I use, the lovers are insufficient. I am attaching the project, I could not solve the problem, can you help?
 
It does not save the coating unit weight because 90 kg/m2 is entered. If you get the coating unit weight correctly, it saves it very easily. Best Regards...

Solar panels will be placed on the building, therefore 90 kg/ I need to buy m2 Thank you for your reply.
 
Hello there; If you remove your purlins from the analysis and divide by all intersections, the problem is solved with some cross section increase. When you remove your purlins from the analysis, you should use roof braces to provide horizontal stability for the roof. Arrangements have been made in this direction in your project. No problems appear. Since your coating loads are high, the increase in section is at the normal level. Good work.
 
good day, in my project, I removed the purlins from the analysis, but even though I increased the cross section, I cannot save the purlins. I do not want to use very large sections within 6 m span, my roof slope is 21%, you said before that this problem may occur on roofs above 25%. My project is in the attachment, I would appreciate if you could help. The file size is large I downloaded it as rar.
 
Hello there; ***You have defined 2 modal analyzes, but there is only one choice for ex and ey in the Design Spectra section, a confusion appears in the earthquake loads. I removed one in your model. You can reanalyze by changing the design spectrum in the analysis settings - ground section. However, it will not be easy to control the program in 2 modal analyzes at the same time. The case of removing the purlins from the analysis is valid for roof purlins and there is no problem with your roof purlins. There seems to be a problem in your facade purlins, the reason is the deflection problem. In version 8.62, we have a bug in the deflection control that has been mentioned in the forum before. This problem also appears in the sidewall purlins. Necessary work has been done for this problem, but unfortunately, there is no solution available in the current version. Note: In order to reduce the cross-section of the roof purlins, you can adjust the spacing from 120 cm to 1m in mattresses in accordance with the coverings. Some adjustments have been made to your model. You can compare if you wish, be sure to check the loads. Good work.
 
Nurgül, first of all, thank you for your correction. Finally, you said that the source of my deflection problem will be due to version 8.62, which version do I need to install so that I don't encounter this problem again?
 
Hello there; You can change the direction of the Facade lovers according to the situation specified by your teacher. However, since the coatings on the purlins are properly terminated on the field to prevent water accumulation, the direction of the purlin groups is not very important, but if you want to take precautions without leaving them on the field, change the direction of the facade purlins to 0. The latest version for demo is 8.62. You can simply calculate the deflection manually, or you can perform the modeling with a simple support placed between 2 columns in the program and control it by entering the loads on it. Good work.
