Good morning.
I am a beginner and I do not know Physics well.
I am designing a pull-up bar for my son who plays sports.
I would like to know, please, what kind of analysis can I do to know the characteristics that the wall and the dowels must have? What traction does the bar apply to the wall?
My son’s mass is 70 kg.
I attach the design project together with the mesh, without analysis.
Thanks to everyone and to anyone who wants to give me a little suggestion

The mesh is rather coarse (especially in the brackets), you should try refining it and see how it affects the results.
Joints like connection with the wall are usually not simulated in FEA but chosen based on hand calculations. You can get the forces there by adding history outputs with RF (reaction force) requested with Totals to get the sum.
in general case of designing steel or any metallic member, it’s required to check the strength and stability. Strength criteria required to consider plasticity in material, later on stability is buckling analysis. Both requirement can be satisfied by perform nonlinear analysis of material and large deformation, commonly an imperfection and residual stress need to prepare.
Related to specific sketch of problem provided, compression only support may need, spring element to modeling of bolt also.
