Deflection problem at twenty meters span

Hello everyone, I am trying to pass the 20 meter span with honeycomb beam, but it gives a deflection limit error. How can I get past this gap with this system? I also preferred to solve the project with YDKT, I want to run the profiles up to the nominal strength limit. I would be very happy if you would review the system in general, point out my deficiencies or errors, and give your suggestions for me to exceed the deflection limit. I wish you good work.
 
Re: 20 meters of deflection problem Hello; As a result of an error made during modeling, a serious deflection is seen at the middle axle ends of your honeycomb beams. For this reason, your model has been edited. For details about the program, we recommend you to model the logic in the videos.

You can continue your model through editing. Good work.
 
Re: Deflection problem at 20 meters span I was able to open the file, all the profiles seem to be sufficient in your arrangement, but I could not understand what you changed, you removed the connections that connect the honeycomb beams to the columns and the wind connections, this way the system saved me. Could you please explain what was my mistake in my design, it is very important for me to know where I went wrong, thank you very much by the way
 
Re: The deflection problem at 20 meters span You also removed the crosses between the columns, I read your comment on the forum that "the crosses on the roof should be continued on the columns" in a similar design, I was confused.
 
Re: 20 meters of deflection problem Hello; The reason for the error is the confusion in the nodal points due to the stability beams being inserted too close. As you can see in the image, your main beams were not supported to each other. We did not remodel crosses and other elements and joins so you can continue your project. In order to control the problem on the roof, only the roof was fully intervened. Create the actions on the side by watching the videos as I mentioned. - For example, you don't need to create the purlins one by one at each interval. -Complete the side facade cross and purlin operations. To the stability beam on the roof; When the design details of honeycomb beams are examined, it is seen that there is no need. However, by examining the general behavior of the structure, you can remodel it if you decide as an engineer that it is necessary for stability behavior. During this modeling, you can insert the stability beams at a distance of 0.3-0.4 m from the joint of the 2 main beams, avoiding collisions. Good work.
