WEIRD REACTIONS IN ROBOT 2019

[jmusopole]

I modeled a building in Robot 2019. I analysed it and discovered that the reactions at most points are very weird. I don't know what to do to resolve this and I need assistance.

Please, feel free to flag anything else that might be wrong with the model.

Model and screenshot attached.

Kind regards

   You cannot ignore instability type 1 warnings. Watch official autodesk webinars on Build your Robot Structural Analysis IQ - YouTube  . Webinar 16 for instability warnings.

   All your type 1 warnings are due to excessive releases on your roof trusses . Keep the chords without releases and set the diagonals as truss bars.

   Also , there regions on your panel meshes with a heavy concentration of nodes . Probably due to imprecise panel/bar geometry.

Also watch webinars 1 and 2 about meshing
