Excesive deformation on bracings

[ARQLABS08]

Hi, I analyzing a steel frame warehouse, in modal analysis, the thing is that when I put the bracing in the roof the bracings results to have a excesive deformation in all modes, and increase a lot the period and reduce the mass participation, as you can see in the picture. When I increase the section of the round bar reduce the period and increase the mass participation, but still have the excesive deformation. I dont know why, i had tried to pinned-pinned bracings didnt work, release RX and didnt work. I was told that using tension only bars is not compatible with DSC algorithm, so, thats why i am not using it.

If some could help would be great.

I couldn't upload the model because is too heavy

Thanks.

Hi @ARQLABS08 

Save your model without results and zip it before attaching
